+Changes in synapse v0.9.3 (2015-07-01)
+======================================
+
+No changes from v0.9.3 Release Candidate 1.
+
+Changes in synapse v0.9.3-rc1 (2015-06-23)
+==========================================
+
+General:
+
+* Fix a memory leak in the notifier. (SYN-412)
+* Improve performance of room initial sync. (SYN-418)
+* General improvements to logging.
+* Remove ``access_token`` query params from ``INFO`` level logging.
+
+Configuration:
+
+* Add support for specifying and configuring multiple listeners. (SYN-389)
+
+Application services:
+
+* Fix bug where synapse failed to send user queries to application services.
+
+Changes in synapse v0.9.2-r2 (2015-06-15)
+=========================================
+
+Fix packaging so that schema delta python files get included in the package.
+
+Changes in synapse v0.9.2 (2015-06-12)
+======================================
+
+General:
+
+* Use ultrajson for json (de)serialisation when a canonical encoding is not
+  required. Ultrajson is significantly faster than simplejson in certain
+  circumstances.
+* Use connection pools for outgoing HTTP connections.
+* Process thumbnails on separate threads.
+
+Configuration:
+
+* Add option, ``gzip_responses``, to disable HTTP response compression.
+
+Federation:
+
+* Improve resilience of backfill by ensuring we fetch any missing auth events.
+* Improve performance of backfill and joining remote rooms by removing
+  unnecessary computations. This included handling events we'd previously
+  handled as well as attempting to compute the current state for outliers.
+
+
+Changes in synapse v0.9.1 (2015-05-26)
+======================================
+
+General:
+
+* Add support for backfilling when a client paginates. This allows servers to
+  request history for a room from remote servers when a client tries to
+  paginate history the server does not have - SYN-36
+* Fix bug where you couldn't disable non-default pushrules - SYN-378
+* Fix ``register_new_user`` script - SYN-359
+* Improve performance of fetching events from the database, this improves both
+  initialSync and sending of events.
+* Improve performance of event streams, allowing synapse to handle more
+  simultaneous connected clients.
+
+Federation:
+
+* Fix bug with existing backfill implementation where it returned the wrong
+  selection of events in some circumstances.
+* Improve performance of joining remote rooms.
+
+Configuration:
+
+* Add support for changing the bind host of the metrics listener via the
+  ``metrics_bind_host`` option.
+ 
+
+Changes in synapse v0.9.0-r5 (2015-05-21)
+=========================================
+
+* Add more database caches to reduce amount of work done for each pusher. This
+  radically reduces CPU usage when multiple pushers are set up in the same room.
+
+Changes in synapse v0.9.0 (2015-05-07)
+======================================
+
+General:
+
+* Add support for using a PostgreSQL database instead of SQLite. See
+  `docs/postgres.rst`_ for details.
+* Add password change and reset APIs. See `Registration`_ in the spec.
+* Fix memory leak due to not releasing stale notifiers - SYN-339.
+* Fix race in caches that occasionally caused some presence updates to be
+  dropped - SYN-369.
+* Check server name has not changed on restart.
+* Add a sample systemd unit file and a logger configuration in
+  contrib/systemd. Contributed Ivan Shapovalov.
+
+Federation:
+
+* Add key distribution mechanisms for fetching public keys of unavailable
+  remote home servers. See `Retrieving Server Keys`_ in the spec.
+
+Configuration:
+
+* Add support for multiple config files.
+* Add support for dictionaries in config files.
+* Remove support for specifying config options on the command line, except
+  for:
+
+  * ``--daemonize`` - Daemonize the home server.
+  * ``--manhole`` - Turn on the twisted telnet manhole service on the given
+    port.
+  * ``--database-path`` - The path to a sqlite database to use.
+  * ``--verbose`` - The verbosity level.
+  * ``--log-file`` - File to log to.
+  * ``--log-config`` - Python logging config file.
+  * ``--enable-registration`` - Enable registration for new users.
+
+Application services:
+
+* Reliably retry sending of events from Synapse to application services, as per
+  `Application Services`_ spec.
+* Application services can no longer register via the ``/register`` API,
+  instead their configuration should be saved to a file and listed in the
+  synapse ``app_service_config_files`` config option. The AS configuration file
+  has the same format as the old ``/register`` request.
+  See `docs/application_services.rst`_ for more information.

+Changes in synapse v0.8.1 (2015-03-18)
+======================================
+
+* Disable registration by default. New users can be added using the command
+  ``register_new_matrix_user`` or by enabling registration in the config.
+* Add metrics to synapse. To enable metrics use config options
+  ``enable_metrics`` and ``metrics_port``.
+* Fix bug where banning only kicked the user.
+
+Changes in synapse v0.8.0 (2015-03-06)
+======================================
+
+General:
+
+* Add support for registration fallback. This is a page hosted on the server
+  which allows a user to register for an account, regardless of what client
+  they are using (e.g. mobile devices).
+
+* Added new default push rules and made them configurable by clients:
+
+  * Suppress all notice messages.
+  * Notify when invited to a new room.
+  * Notify for messages that don't match any rule.
+  * Notify on incoming call.
+
+Federation:
+
+* Added per host server side rate-limiting of incoming federation requests.
+* Added a ``/get_missing_events/`` API to federation to reduce number of
+  ``/events/`` requests.
+
+Configuration:
+
+* Added configuration option to disable registration:
+  ``disable_registration``.
+* Added configuration option to change soft limit of number of open file
+  descriptors: ``soft_file_limit``.
+* Make ``tls_private_key_path`` optional when running with ``no_tls``.
+
+Application services:
+
+* Application services can now poll on the CS API ``/events`` for their events,
+  by providing their application service ``access_token``.
+* Added exclusive namespace support to application services API.
+
+
+Changes in synapse v0.7.1 (2015-02-19)
+======================================
+
+* Initial alpha implementation of parts of the Application Services API.
+  Including:
+
+  - AS Registration / Unregistration
+  - User Query API
+  - Room Alias Query API
+  - Push transport for receiving events.
+  - User/Alias namespace admin control
+
+* Add cache when fetching events from remote servers to stop repeatedly
+  fetching events with bad signatures.
+* Respect the per remote server retry scheme when fetching both events and
+  server keys to reduce the number of times we send requests to dead servers.
+* Inform remote servers when the local server fails to handle a received event.
+* Turn off python bytecode generation due to problems experienced when
+  upgrading from previous versions.
+
+Changes in synapse v0.7.0 (2015-02-12)
+======================================
+
+* Add initial implementation of the query auth federation API, allowing
+  servers to agree on whether an event should be allowed or rejected.
+* Persist events we have rejected from federation, fixing the bug where
+  servers would keep requesting the same events.
+* Various federation performance improvements, including:
+
+  - Add in memory caches on queries such as:
+
+     * Computing the state of a room at a point in time, used for
+       authorization on federation requests.
+     * Fetching events from the database.
+     * User's room membership, used for authorizing presence updates.
+
+  - Upgraded JSON library to improve parsing and serialisation speeds.
+
+* Add default avatars to new user accounts using pydenticon library.
+* Correctly time out federation requests.
+* Retry federation requests against different servers.
+* Add support for push and push rules.
+* Add alpha versions of proposed new CSv2 APIs, including ``/sync`` API.
+
+Changes in synapse 0.6.1 (2015-01-07)
+=====================================
+
+* Major optimizations to improve performance of initial sync and event sending
+  in large rooms (by up to 10x)
+* Media repository now includes a Content-Length header on media downloads.
+* Improve quality of thumbnails by changing resizing algorithm.
+
+Changes in synapse 0.6.0 (2014-12-16)
+=====================================
+
+* Add new API for media upload and download that supports thumbnailing.
+* Replicate media uploads over multiple homeservers so media is always served
+  to clients from their local homeserver.  This obsoletes the
+  --content-addr parameter and confusion over accessing content directly
+  from remote homeservers.
+* Implement exponential backoff when retrying federation requests when
+  sending to remote homeservers which are offline.
+* Implement typing notifications.
+* Fix bugs where we sent events with invalid signatures due to bugs where
+  we incorrectly persisted events.
+* Improve performance of database queries involving retrieving events.
+
+Changes in synapse 0.5.4a (2014-12-13)
+======================================
+
+* Fix bug while generating the error message when a file path specified in
+  the config doesn't exist.
+
+Changes in synapse 0.5.4 (2014-12-03)
+=====================================
+
+* Fix presence bug where some rooms did not display presence updates for
+  remote users.
+* Do not log SQL timing log lines when started with "-v"
+* Fix potential memory leak.
+
+Changes in synapse 0.5.3c (2014-12-02)
+======================================
+
+* Change the default value for the `content_addr` option to use the HTTP
+  listener, as by default the HTTPS listener will be using a self-signed
+  certificate.
+
+Changes in synapse 0.5.3 (2014-11-27)
+=====================================
+
+* Fix bug that caused joining a remote room to fail if a single event was not
+  signed correctly.
+* Fix bug which caused servers to continuously try and fetch events from other
+  servers.
+
+Changes in synapse 0.5.2 (2014-11-26)

+   banned in from the recents list.
+
+Changes in synapse 0.3.0 (2014-09-18)
+=====================================
+See UPGRADE for information about changes to the client server API, including
+breaking backwards compatibility with VoIP calls and registration API.
+
+Homeserver:
+ * When a user changes their displayname or avatar the server will now update 
+   all their join states to reflect this.
+ * The server now adds "age" key to events to indicate how old they are. This
+   is clock independent, so at no point does any server or webclient have to
+   assume their clock is in sync with everyone else.

+   'type':'m.login.password'. See UPGRADE for more information on this.
+ * The 'user_id' key has been renamed to 'user' to better match the login API.
+ * There is an additional login type: 'm.login.email.identity'.
+ * The command client and web client have been updated to reflect these changes.
+
+Changes in synapse 0.2.3 (2014-09-12)
+=====================================

-# Contributing code to Synapse
-
-Everyone is welcome to contribute code to [matrix.org
-projects](https://github.com/matrix-org), provided that they are willing to
-license their contributions under the same license as the project itself. We
-follow a simple 'inbound=outbound' model for contributions: the act of
-submitting an 'inbound' contribution means that the contributor agrees to
-license the code under the same terms as the project's overall 'outbound'
-license - in our case, this is almost always Apache Software License v2 (see
-[LICENSE](LICENSE)).
-
-## How to contribute
-
-The preferred and easiest way to contribute changes is to fork the relevant
-project on github, and then [create a pull request](
-https://help.github.com/articles/using-pull-requests/) to ask us to pull your
-changes into our repo.
-
-Some other points to follow:
-
- * Please base your changes on the `develop` branch.
-
- * Please follow the [code style requirements](#code-style).
-
- * Please include a [changelog entry](#changelog) with each PR.
-
- * Please [sign off](#sign-off) your contribution.
-
- * Please keep an eye on the pull request for feedback from the [continuous
-   integration system](#continuous-integration-and-testing) and try to fix any
-   errors that come up.
-
- * If you need to [update your PR](#updating-your-pull-request), just add new
-   commits to your branch rather than rebasing.
-
-## Code style
-
-Synapse's code style is documented [here](docs/code_style.md). Please follow
-it, including the conventions for the [sample configuration
-file](docs/code_style.md#configuration-file-format).
-
-Many of the conventions are enforced by scripts which are run as part of the
-[continuous integration system](#continuous-integration-and-testing). To help
-check if you have followed the code style, you can run `scripts-dev/lint.sh`
-locally. You'll need python 3.6 or later, and to install a number of tools:
-
-```
-# Install the dependencies
-pip install -e ".[lint]"
-
-# Run the linter script
-./scripts-dev/lint.sh
-```
-
-**Note that the script does not just test/check, but also reformats code, so you
-may wish to ensure any new code is committed first**.
-
-By default, this script checks all files and can take some time; if you alter
-only certain files, you might wish to specify paths as arguments to reduce the
-run-time:
-
-```
-./scripts-dev/lint.sh path/to/file1.py path/to/file2.py path/to/folder
-```
-
-You can also provided the `-d` option, which will lint the files that have been
-changed since the last git commit. This will often be significantly faster than
-linting the whole codebase.
-
-Before pushing new changes, ensure they don't produce linting errors. Commit any
-files that were corrected.
-
-Please ensure your changes match the cosmetic style of the existing project,
-and **never** mix cosmetic and functional changes in the same commit, as it
-makes it horribly hard to review otherwise.
-
-## Changelog
-
-All changes, even minor ones, need a corresponding changelog / newsfragment
-entry. These are managed by [Towncrier](https://github.com/hawkowl/towncrier).
-
-To create a changelog entry, make a new file in the `changelog.d` directory named
-in the format of `PRnumber.type`. The type can be one of the following:
-
-* `feature`
-* `bugfix`
-* `docker` (for updates to the Docker image)
-* `doc` (for updates to the documentation)
-* `removal` (also used for deprecations)
-* `misc` (for internal-only changes)
-
-This file will become part of our [changelog](
-https://github.com/matrix-org/synapse/blob/master/CHANGES.md) at the next
-release, so the content of the file should be a short description of your
-change in the same style as the rest of the changelog. The file can contain Markdown
-formatting, and should end with a full stop (.) or an exclamation mark (!) for
-consistency.
-
-Adding credits to the changelog is encouraged, we value your
-contributions and would like to have you shouted out in the release notes!
-
-For example, a fix in PR #1234 would have its changelog entry in
-`changelog.d/1234.bugfix`, and contain content like:
-
-> The security levels of Florbs are now validated when received
-> via the `/federation/florb` endpoint. Contributed by Jane Matrix.
-
-If there are multiple pull requests involved in a single bugfix/feature/etc,
-then the content for each `changelog.d` file should be the same. Towncrier will
-merge the matching files together into a single changelog entry when we come to
-release.
-
-### How do I know what to call the changelog file before I create the PR?
-
-Obviously, you don't know if you should call your newsfile
-`1234.bugfix` or `5678.bugfix` until you create the PR, which leads to a
-chicken-and-egg problem.
-
-There are two options for solving this:
-
- 1. Open the PR without a changelog file, see what number you got, and *then*
-    add the changelog file to your branch (see [Updating your pull
-    request](#updating-your-pull-request)), or:
-
- 1. Look at the [list of all
-    issues/PRs](https://github.com/matrix-org/synapse/issues?q=), add one to the
-    highest number you see, and quickly open the PR before somebody else claims
-    your number.
-
-    [This
-    script](https://github.com/richvdh/scripts/blob/master/next_github_number.sh)
-    might be helpful if you find yourself doing this a lot.
-
-Sorry, we know it's a bit fiddly, but it's *really* helpful for us when we come
-to put together a release!
-
-### Debian changelog
-
-Changes which affect the debian packaging files (in `debian`) are an
-exception to the rule that all changes require a `changelog.d` file.
-
-In this case, you will need to add an entry to the debian changelog for the
-next release. For this, run the following command:
-
-```
-dch
-```
-
-This will make up a new version number (if there isn't already an unreleased
-version in flight), and open an editor where you can add a new changelog entry.
-(Our release process will ensure that the version number and maintainer name is
-corrected for the release.)
-
-If your change affects both the debian packaging *and* files outside the debian
-directory, you will need both a regular newsfragment *and* an entry in the
-debian changelog. (Though typically such changes should be submitted as two
-separate pull requests.)
-

-flag to `git commit`, which uses the name and email set in your
-`user.name` and `user.email` git configs.
-
-## Continuous integration and testing
-
-[Buildkite](https://buildkite.com/matrix-dot-org/synapse) will automatically
-run a series of checks and tests against any PR which is opened against the
-project; if your change breaks the build, this will be shown in GitHub, with
-links to the build results. If your build fails, please try to fix the errors
-and update your branch.
-
-To run unit tests in a local development environment, you can use:
-
-- ``tox -e py35`` (requires tox to be installed by ``pip install tox``)
-  for SQLite-backed Synapse on Python 3.5.
-- ``tox -e py36`` for SQLite-backed Synapse on Python 3.6.
-- ``tox -e py36-postgres`` for PostgreSQL-backed Synapse on Python 3.6
-  (requires a running local PostgreSQL with access to create databases).
-- ``./test_postgresql.sh`` for PostgreSQL-backed Synapse on Python 3.5
-  (requires Docker). Entirely self-contained, recommended if you don't want to
-  set up PostgreSQL yourself.
-
-Docker images are available for running the integration tests (SyTest) locally,
-see the [documentation in the SyTest repo](
-https://github.com/matrix-org/sytest/blob/develop/docker/README.md) for more
-information.
-
-## Updating your pull request
-
-If you decide to make changes to your pull request - perhaps to address issues
-raised in a review, or to fix problems highlighted by [continuous
-integration](#continuous-integration-and-testing) - just add new commits to your
-branch, and push to GitHub. The pull request will automatically be updated.
-
-Please **avoid** rebasing your branch, especially once the PR has been
-reviewed: doing so makes it very difficult for a reviewer to see what has
-changed since a previous review.
-
-## Notes for maintainers on merging PRs etc
-
-There are some notes for those with commit access to the project on how we
-manage git [here](docs/dev/git.md).
-
-## Conclusion
-
-That's it! Matrix is a very open and collaborative project as you might expect
-given our obsession with open communication. If we're going to successfully
-matrix together all the fragmented communication technologies out there we are
-reliant on contributions and collaboration from the community to do so. So
-please get involved - and we hope you have as much fun hacking on Matrix as we
-do!

+Contributing code to Matrix
+===========================
+
+Everyone is welcome to contribute code to Matrix
+(https://github.com/matrix-org), provided that they are willing to license
+their contributions under the same license as the project itself. We follow a
+simple 'inbound=outbound' model for contributions: the act of submitting an
+'inbound' contribution means that the contributor agrees to license the code
+under the same terms as the project's overall 'outbound' license - in our
+case, this is almost always Apache Software License v2 (see LICENSE).
+
+How to contribute
+~~~~~~~~~~~~~~~~~
+
+The preferred and easiest way to contribute changes to Matrix is to fork the
+relevant project on github, and then create a pull request to ask us to pull
+your changes into our repo
+(https://help.github.com/articles/using-pull-requests/)
+
+**The single biggest thing you need to know is: please base your changes on
+the develop branch - /not/ master.**
+
+We use the master branch to track the most recent release, so that folks who
+blindly clone the repo and automatically check out master get something that
+works. Develop is the unstable branch where all the development actually
+happens: the workflow is that contributors should fork the develop branch to
+make a 'feature' branch for a particular contribution, and then make a pull
+request to merge this back into the matrix.org 'official' develop branch. We
+use github's pull request workflow to review the contribution, and either ask
+you to make any refinements needed or merge it and make them ourselves. The
+changes will then land on master when we next do a release.
+
+We use Jenkins for continuous integration (http://matrix.org/jenkins), and
+typically all pull requests get automatically tested Jenkins: if your change breaks the build, Jenkins will yell about it in #matrix-dev:matrix.org so please lurk there and keep an eye open.
+
+Code style
+~~~~~~~~~~
+
+All Matrix projects have a well-defined code-style - and sometimes we've even
+got as far as documenting it... For instance, synapse's code style doc lives
+at https://github.com/matrix-org/synapse/tree/master/docs/code_style.rst.
+
+Please ensure your changes match the cosmetic style of the existing project,
+and **never** mix cosmetic and functional changes in the same commit, as it
+makes it horribly hard to review otherwise.
+
+Attribution
+~~~~~~~~~~~
+
+Everyone who contributes anything to Matrix is welcome to be listed in the
+AUTHORS.rst file for the project in question. Please feel free to include a
+change to AUTHORS.rst in your pull request to list yourself and a short
+description of the area(s) you've worked on. Also, we sometimes have swag to
+give away to contributors - if you feel that Matrix-branded apparel is missing
+from your life, please mail us your shipping address to matrix at matrix.org and we'll try to fix it :)
+
+Sign off
+~~~~~~~~
+
+In order to have a concrete record that your contribution is intentional
+and you agree to license it under the same terms as the project's license, we've adopted the
+same lightweight approach that the Linux Kernel
+(https://www.kernel.org/doc/Documentation/SubmittingPatches), Docker
+(https://github.com/docker/docker/blob/master/CONTRIBUTING.md), and many other
+projects use: the DCO (Developer Certificate of Origin:
+http://developercertificate.org/). This is a simple declaration that you wrote
+the contribution or otherwise have the right to contribute it to Matrix::
+
+    Developer Certificate of Origin
+    Version 1.1

+
+    By making a contribution to this project, I certify that:
+
+    (a) The contribution was created in whole or in part by me and I
+        have the right to submit it under the open source license
+        indicated in the file; or
+
+    (b) The contribution is based upon previous work that, to the best
+        of my knowledge, is covered under an appropriate open source
+        license and I have the right under that license to submit that
+        work with modifications, whether created in whole or in part
+        by me, under the same open source license (unless I am
+        permitted to submit under a different license), as indicated
+        in the file; or
+
+    (c) The contribution was provided directly to me by some other
+        person who certified (a), (b) or (c) and I have not modified
+        it.
+
+    (d) I understand and agree that this project and the contribution
+        are public and that a record of the contribution (including all
+        personal information I submit with it, including my sign-off) is
+        maintained indefinitely and may be redistributed consistent with
+        this project or the open source license(s) involved.
+        
+If you agree to this for your contribution, then all that's needed is to
+include the line in your commit or pull request comment::
+
+    Signed-off-by: Your Name <your@email.example.org>
+    
+...using your real name; unfortunately pseudonyms and anonymous contributions
+can't be accepted. Git makes this trivial - just use the -s flag when you do
+``git commit``, having first set ``user.name`` and ``user.email`` git configs
+(which you should have done anyway :)
+
+Conclusion
+~~~~~~~~~~
+
+That's it!  Matrix is a very open and collaborative project as you might expect given our obsession with open communication.  If we're going to successfully matrix together all the fragmented communication technologies out there we are reliant on contributions and collaboration from the community to do so.

-
-# Choosing your server name
-
-It is important to choose the name for your server before you install Synapse,
-because it cannot be changed later.
-
-The server name determines the "domain" part of user-ids for users on your
-server: these will all be of the format `@user:my.domain.name`. It also
-determines how other matrix servers will reach yours for federation.
-
-For a test configuration, set this to the hostname of your server. For a more
-production-ready setup, you will probably want to specify your domain
-(`example.com`) rather than a matrix-specific hostname here (in the same way
-that your email address is probably `user@example.com` rather than
-`user@email.example.com`) - but doing so may require more advanced setup: see
-[Setting up Federation](docs/federate.md).
-
-# Picking a database engine
-
-Synapse offers two database engines:
- * [PostgreSQL](https://www.postgresql.org)
- * [SQLite](https://sqlite.org/)
-
-Almost all installations should opt to use PostgreSQL. Advantages include:
-
-* significant performance improvements due to the superior threading and
-  caching model, smarter query optimiser
-* allowing the DB to be run on separate hardware
-
-For information on how to install and use PostgreSQL, please see
-[docs/postgres.md](docs/postgres.md)
-
-By default Synapse uses SQLite and in doing so trades performance for convenience.
-SQLite is only recommended in Synapse for testing purposes or for servers with
-light workloads.
-
-# Installing Synapse
-
-## Installing from source
-
-(Prebuilt packages are available for some platforms - see [Prebuilt packages](#prebuilt-packages).)
-
-System requirements:
-
-- POSIX-compliant system (tested on Linux & OS X)
-- Python 3.5.2 or later, up to Python 3.8.
-- At least 1GB of free RAM if you want to join large public rooms like #matrix:matrix.org
-
-Synapse is written in Python but some of the libraries it uses are written in
-C. So before we can install Synapse itself we need a working C compiler and the
-header files for Python C extensions. See [Platform-Specific
-Instructions](#platform-specific-instructions) for information on installing
-these on various platforms.
-
-To install the Synapse homeserver run:
-
-```
-mkdir -p ~/synapse
-virtualenv -p python3 ~/synapse/env
-source ~/synapse/env/bin/activate
-pip install --upgrade pip
-pip install --upgrade setuptools
-pip install matrix-synapse
-```
-
-This will download Synapse from [PyPI](https://pypi.org/project/matrix-synapse)
-and install it, along with the python libraries it uses, into a virtual environment
-under `~/synapse/env`.  Feel free to pick a different directory if you
-prefer.
-
-This Synapse installation can then be later upgraded by using pip again with the
-update flag:
-
-```
-source ~/synapse/env/bin/activate
-pip install -U matrix-synapse
-```
-
-Before you can start Synapse, you will need to generate a configuration
-file. To do this, run (in your virtualenv, as before):
-
-```
-cd ~/synapse
-python -m synapse.app.homeserver \
-    --server-name my.domain.name \
-    --config-path homeserver.yaml \
-    --generate-config \
-    --report-stats=[yes|no]
-```
-
-... substituting an appropriate value for `--server-name`.
-
-This command will generate you a config file that you can then customise, but it will
-also generate a set of keys for you. These keys will allow your homeserver to
-identify itself to other homeserver, so don't lose or delete them. It would be
-wise to back them up somewhere safe. (If, for whatever reason, you do need to
-change your homeserver's keys, you may find that other homeserver have the
-old key cached. If you update the signing key, you should change the name of the
-key in the `<server name>.signing.key` file (the second word) to something
-different. See the
-[spec](https://matrix.org/docs/spec/server_server/latest.html#retrieving-server-keys)
-for more information on key management).
-
-To actually run your new homeserver, pick a working directory for Synapse to
-run (e.g. `~/synapse`), and:
-
-```
-cd ~/synapse
-source env/bin/activate
-synctl start
-```
-
-### Platform-Specific Instructions
-
-#### Debian/Ubuntu/Raspbian
-
-Installing prerequisites on Ubuntu or Debian:
-
-```
-sudo apt-get install build-essential python3-dev libffi-dev \
-                     python3-pip python3-setuptools sqlite3 \
-                     libssl-dev virtualenv libjpeg-dev libxslt1-dev
-```
-
-#### ArchLinux
-
-Installing prerequisites on ArchLinux:
-
-```
-sudo pacman -S base-devel python python-pip \
-               python-setuptools python-virtualenv sqlite3
-```
-
-#### CentOS/Fedora
-
-Installing prerequisites on CentOS 8 or Fedora>26:
-
-```
-sudo dnf install libtiff-devel libjpeg-devel libzip-devel freetype-devel \
-                 libwebp-devel tk-devel redhat-rpm-config \
-                 python3-virtualenv libffi-devel openssl-devel
-sudo dnf groupinstall "Development Tools"
-```
-
-Installing prerequisites on CentOS 7 or Fedora<=25:
-
-```
-sudo yum install libtiff-devel libjpeg-devel libzip-devel freetype-devel \
-                 lcms2-devel libwebp-devel tcl-devel tk-devel redhat-rpm-config \
-                 python3-virtualenv libffi-devel openssl-devel
-sudo yum groupinstall "Development Tools"
-```
-
-Note that Synapse does not support versions of SQLite before 3.11, and CentOS 7
-uses SQLite 3.7. You may be able to work around this by installing a more
-recent SQLite version, but it is recommended that you instead use a Postgres
-database: see [docs/postgres.md](docs/postgres.md).
-
-#### macOS
-
-Installing prerequisites on macOS:
-
-```
-xcode-select --install
-sudo easy_install pip
-sudo pip install virtualenv
-brew install pkg-config libffi
-```
-
-On macOS Catalina (10.15) you may need to explicitly install OpenSSL
-via brew and inform `pip` about it so that `psycopg2` builds:
-
-```
-brew install openssl@1.1
-export LDFLAGS=-L/usr/local/Cellar/openssl\@1.1/1.1.1d/lib/
-```
-
-#### OpenSUSE
-
-Installing prerequisites on openSUSE:
-
-```
-sudo zypper in -t pattern devel_basis
-sudo zypper in python-pip python-setuptools sqlite3 python-virtualenv \
-               python-devel libffi-devel libopenssl-devel libjpeg62-devel
-```
-
-#### OpenBSD
-
-A port of Synapse is available under `net/synapse`. The filesystem
-underlying the homeserver directory (defaults to `/var/synapse`) has to be
-mounted with `wxallowed` (cf. `mount(8)`), so creating a separate filesystem
-and mounting it to `/var/synapse` should be taken into consideration.
-
-To be able to build Synapse's dependency on python the `WRKOBJDIR`
-(cf. `bsd.port.mk(5)`) for building python, too, needs to be on a filesystem
-mounted with `wxallowed` (cf. `mount(8)`).
-
-Creating a `WRKOBJDIR` for building python under `/usr/local` (which on a
-default OpenBSD installation is mounted with `wxallowed`):
-
-```
-doas mkdir /usr/local/pobj_wxallowed
-```
-
-Assuming `PORTS_PRIVSEP=Yes` (cf. `bsd.port.mk(5)`) and `SUDO=doas` are
-configured in `/etc/mk.conf`:
-
-```
-doas chown _pbuild:_pbuild /usr/local/pobj_wxallowed
-```
-
-Setting the `WRKOBJDIR` for building python:
-
-```
-echo WRKOBJDIR_lang/python/3.7=/usr/local/pobj_wxallowed  \\nWRKOBJDIR_lang/python/2.7=/usr/local/pobj_wxallowed >> /etc/mk.conf
-```
-
-Building Synapse:
-
-```
-cd /usr/ports/net/synapse
-make install
-```
-
-#### Windows
-
-If you wish to run or develop Synapse on Windows, the Windows Subsystem For
-Linux provides a Linux environment on Windows 10 which is capable of using the
-Debian, Fedora, or source installation methods. More information about WSL can
-be found at https://docs.microsoft.com/en-us/windows/wsl/install-win10 for
-Windows 10 and https://docs.microsoft.com/en-us/windows/wsl/install-on-server
-for Windows Server.
-
-## Prebuilt packages
-
-As an alternative to installing from source, prebuilt packages are available
-for a number of platforms.
-
-### Docker images and Ansible playbooks
-
-There is an offical synapse image available at
-https://hub.docker.com/r/matrixdotorg/synapse which can be used with
-the docker-compose file available at [contrib/docker](contrib/docker). Further
-information on this including configuration options is available in the README
-on hub.docker.com.
-
-Alternatively, Andreas Peters (previously Silvio Fricke) has contributed a
-Dockerfile to automate a synapse server in a single Docker image, at
-https://hub.docker.com/r/avhost/docker-matrix/tags/
-
-Slavi Pantaleev has created an Ansible playbook,
-which installs the offical Docker image of Matrix Synapse
-along with many other Matrix-related services (Postgres database, Element, coturn,
-ma1sd, SSL support, etc.).
-For more details, see
-https://github.com/spantaleev/matrix-docker-ansible-deploy
-
-
-### Debian/Ubuntu
-
-#### Matrix.org packages
-
-Matrix.org provides Debian/Ubuntu packages of the latest stable version of
-Synapse via https://packages.matrix.org/debian/. They are available for Debian
-9 (Stretch), Ubuntu 16.04 (Xenial), and later. To use them:
-
-```
-sudo apt install -y lsb-release wget apt-transport-https
-sudo wget -O /usr/share/keyrings/matrix-org-archive-keyring.gpg https://packages.matrix.org/debian/matrix-org-archive-keyring.gpg
-echo "deb [signed-by=/usr/share/keyrings/matrix-org-archive-keyring.gpg] https://packages.matrix.org/debian/ $(lsb_release -cs) main" |
-    sudo tee /etc/apt/sources.list.d/matrix-org.list
-sudo apt update
-sudo apt install matrix-synapse-py3
-```
-
-**Note**: if you followed a previous version of these instructions which
-recommended using `apt-key add` to add an old key from
-`https://matrix.org/packages/debian/`, you should note that this key has been
-revoked. You should remove the old key with `sudo apt-key remove
-C35EB17E1EAE708E6603A9B3AD0592FE47F0DF61`, and follow the above instructions to
-update your configuration.
-
-The fingerprint of the repository signing key (as shown by `gpg
-/usr/share/keyrings/matrix-org-archive-keyring.gpg`) is
-`AAF9AE843A7584B5A3E4CD2BCF45A512DE2DA058`.
-
-#### Downstream Debian packages
-
-We do not recommend using the packages from the default Debian `buster`
-repository at this time, as they are old and suffer from known security
-vulnerabilities. You can install the latest version of Synapse from
-[our repository](#matrixorg-packages) or from `buster-backports`. Please
-see the [Debian documentation](https://backports.debian.org/Instructions/)
-for information on how to use backports.
-
-If you are using Debian `sid` or testing, Synapse is available in the default
-repositories and it should be possible to install it simply with:
-
-```
-sudo apt install matrix-synapse
-```
-
-#### Downstream Ubuntu packages
-
-We do not recommend using the packages in the default Ubuntu repository
-at this time, as they are old and suffer from known security vulnerabilities.
-The latest version of Synapse can be installed from [our repository](#matrixorg-packages).
-
-### Fedora
-
-Synapse is in the Fedora repositories as `matrix-synapse`:
-
-```
-sudo dnf install matrix-synapse
-```
-
-Oleg Girko provides Fedora RPMs at
-https://obs.infoserver.lv/project/monitor/matrix-synapse
-
-### OpenSUSE
-
-Synapse is in the OpenSUSE repositories as `matrix-synapse`:
-
-```
-sudo zypper install matrix-synapse
-```
-
-### SUSE Linux Enterprise Server
-
-Unofficial package are built for SLES 15 in the openSUSE:Backports:SLE-15 repository at
-https://download.opensuse.org/repositories/openSUSE:/Backports:/SLE-15/standard/
-
-### ArchLinux
-
-The quickest way to get up and running with ArchLinux is probably with the community package
-https://www.archlinux.org/packages/community/any/matrix-synapse/, which should pull in most of
-the necessary dependencies.
-
-pip may be outdated (6.0.7-1 and needs to be upgraded to 6.0.8-1 ):
-
-```
-sudo pip install --upgrade pip
-```
-
-If you encounter an error with lib bcrypt causing an Wrong ELF Class:
-ELFCLASS32 (x64 Systems), you may need to reinstall py-bcrypt to correctly
-compile it under the right architecture. (This should not be needed if
-installing under virtualenv):
-
-```
-sudo pip uninstall py-bcrypt
-sudo pip install py-bcrypt
-```
-
-### Void Linux
-
-Synapse can be found in the void repositories as 'synapse':
-
-```
-xbps-install -Su
-xbps-install -S synapse
-```
-
-### FreeBSD
-
-Synapse can be installed via FreeBSD Ports or Packages contributed by Brendan Molloy from:
-
- - Ports: `cd /usr/ports/net-im/py-matrix-synapse && make install clean`
- - Packages: `pkg install py37-matrix-synapse`
-
-### OpenBSD
-
-As of OpenBSD 6.7 Synapse is available as a pre-compiled binary. The filesystem
-underlying the homeserver directory (defaults to `/var/synapse`) has to be
-mounted with `wxallowed` (cf. `mount(8)`), so creating a separate filesystem
-and mounting it to `/var/synapse` should be taken into consideration.
-
-Installing Synapse:
-
-```
-doas pkg_add synapse
-```
-
-### NixOS
-
-Robin Lambertz has packaged Synapse for NixOS at:
-https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/services/misc/matrix-synapse.nix
-
-# Setting up Synapse
-
-Once you have installed synapse as above, you will need to configure it.
-
-## TLS certificates
-
-The default configuration exposes a single HTTP port on the local
-interface: `http://localhost:8008`. It is suitable for local testing,
-but for any practical use, you will need Synapse's APIs to be served
-over HTTPS.
-
-The recommended way to do so is to set up a reverse proxy on port
-`8448`. You can find documentation on doing so in
-[docs/reverse_proxy.md](docs/reverse_proxy.md).
-
-Alternatively, you can configure Synapse to expose an HTTPS port. To do
-so, you will need to edit `homeserver.yaml`, as follows:
-
-* First, under the `listeners` section, uncomment the configuration for the
-  TLS-enabled listener. (Remove the hash sign (`#`) at the start of
-  each line). The relevant lines are like this:
-
-  ```
-    - port: 8448
-      type: http
-      tls: true
-      resources:
-        - names: [client, federation]
-  ```
-
-* You will also need to uncomment the `tls_certificate_path` and
-  `tls_private_key_path` lines under the `TLS` section. You will need to manage
-  provisioning of these certificates yourself — Synapse had built-in ACME
-  support, but the ACMEv1 protocol Synapse implements is deprecated, not
-  allowed by LetsEncrypt for new sites, and will break for existing sites in
-  late 2020. See [ACME.md](docs/ACME.md).
-
-  If you are using your own certificate, be sure to use a `.pem` file that
-  includes the full certificate chain including any intermediate certificates
-  (for instance, if using certbot, use `fullchain.pem` as your certificate, not
-  `cert.pem`).
-
-For a more detailed guide to configuring your server for federation, see
-[federate.md](docs/federate.md).
-
-## Client Well-Known URI
-
-Setting up the client Well-Known URI is optional but if you set it up, it will
-allow users to enter their full username (e.g. `@user:<server_name>`) into clients
-which support well-known lookup to automatically configure the homeserver and
-identity server URLs. This is useful so that users don't have to memorize or think
-about the actual homeserver URL you are using.
-
-The URL `https://<server_name>/.well-known/matrix/client` should return JSON in
-the following format.
-
-```
-{
-  "m.homeserver": {
-    "base_url": "https://<matrix.example.com>"
-  }
-}
-```
-
-It can optionally contain identity server information as well.
-
-```
-{
-  "m.homeserver": {
-    "base_url": "https://<matrix.example.com>"
-  },
-  "m.identity_server": {
-    "base_url": "https://<identity.example.com>"
-  }
-}
-```
-
-To work in browser based clients, the file must be served with the appropriate
-Cross-Origin Resource Sharing (CORS) headers. A recommended value would be
-`Access-Control-Allow-Origin: *` which would allow all browser based clients to
-view it.
-
-In nginx this would be something like:
-```
-location /.well-known/matrix/client {
-    return 200 '{"m.homeserver": {"base_url": "https://<matrix.example.com>"}}';
-    add_header Content-Type application/json;
-    add_header Access-Control-Allow-Origin *;
-}
-```
-
-You should also ensure the `public_baseurl` option in `homeserver.yaml` is set
-correctly. `public_baseurl` should be set to the URL that clients will use to
-connect to your server. This is the same URL you put for the `m.homeserver`
-`base_url` above.
-
-```
-public_baseurl: "https://<matrix.example.com>"
-```
-
-## Email
-
-It is desirable for Synapse to have the capability to send email. This allows
-Synapse to send password reset emails, send verifications when an email address
-is added to a user's account, and send email notifications to users when they
-receive new messages.
-
-To configure an SMTP server for Synapse, modify the configuration section
-headed `email`, and be sure to have at least the `smtp_host`, `smtp_port`
-and `notif_from` fields filled out.  You may also need to set `smtp_user`,
-`smtp_pass`, and `require_transport_security`.
-
-If email is not configured, password reset, registration and notifications via
-email will be disabled.
-
-## Registering a user
-
-The easiest way to create a new user is to do so from a client like [Element](https://element.io/).
-
-Alternatively you can do so from the command line if you have installed via pip.
-
-This can be done as follows:
-
-```
-$ source ~/synapse/env/bin/activate
-$ synctl start # if not already running
-$ register_new_matrix_user -c homeserver.yaml http://localhost:8008
-New user localpart: erikj
-Password:
-Confirm password:
-Make admin [no]:
-Success!
-```
-
-This process uses a setting `registration_shared_secret` in
-`homeserver.yaml`, which is shared between Synapse itself and the
-`register_new_matrix_user` script. It doesn't matter what it is (a random
-value is generated by `--generate-config`), but it should be kept secret, as
-anyone with knowledge of it can register users, including admin accounts,
-on your server even if `enable_registration` is `false`.
-
-## Setting up a TURN server
-
-For reliable VoIP calls to be routed via this homeserver, you MUST configure
-a TURN server. See [docs/turn-howto.md](docs/turn-howto.md) for details.
-
-## URL previews
-
-Synapse includes support for previewing URLs, which is disabled by default.  To
-turn it on you must enable the `url_preview_enabled: True` config parameter
-and explicitly specify the IP ranges that Synapse is not allowed to spider for
-previewing in the `url_preview_ip_range_blacklist` configuration parameter.
-This is critical from a security perspective to stop arbitrary Matrix users
-spidering 'internal' URLs on your network. At the very least we recommend that
-your loopback and RFC1918 IP addresses are blacklisted.
-
-This also requires the optional `lxml` and `netaddr` python dependencies to be
-installed. This in turn requires the `libxml2` library to be available - on
-Debian/Ubuntu this means `apt-get install libxml2-dev`, or equivalent for
-your OS.
-
-# Troubleshooting Installation
-
-`pip` seems to leak *lots* of memory during installation. For instance, a Linux
-host with 512MB of RAM may run out of memory whilst installing Twisted. If this
-happens, you will have to individually install the dependencies which are
-failing, e.g.:
-
-```
-pip install twisted
-```
-
-If you have any other problems, feel free to ask in
-[#synapse:matrix.org](https://matrix.to/#/#synapse:matrix.org).

 In Matrix, every user runs one or more Matrix clients, which connect through to
-a Matrix homeserver. The homeserver stores all their personal chat history and
-user account information - much as a mail client connects through to an
-IMAP/SMTP server. Just like email, you can either run your own Matrix
-homeserver and control and own your own communications and history or use one

 Synapse Installation
 ====================
 
-.. _federation:
+Synapse is the reference python/twisted Matrix homeserver implementation.
 
-* For details on how to install synapse, see `<INSTALL.md>`_.
-* For specific details on how to configure Synapse for federation see `docs/federate.md <docs/federate.md>`_
+System requirements:
+- POSIX-compliant system (tested on Linux & OS X)
+- Python 2.7
 
+Synapse is written in python but some of the libraries is uses are written in
+C. So before we can install synapse itself we need a working C compiler and the
+header files for python C extensions.
 
-Connecting to Synapse from a client
-===================================
+Installing prerequisites on Ubuntu or Debian::
 
-The easiest way to try out your new Synapse installation is by connecting to it
-from a web client.
+    sudo apt-get install build-essential python2.7-dev libffi-dev \
+                         python-pip python-setuptools sqlite3 \
+                         libssl-dev python-virtualenv libjpeg-dev
+                           
+Installing prerequisites on ArchLinux::
 
-Unless you are running a test instance of Synapse on your local machine, in
-general, you will need to enable TLS support before you can successfully
-connect from a client: see `<INSTALL.md#tls-certificates>`_.
+    sudo pacman -S base-devel python2 python-pip \
+                   python-setuptools python-virtualenv sqlite3
 
-An easy way to get started is to login or register via Element at
-https://app.element.io/#/login or https://app.element.io/#/register respectively.
-You will need to change the server you are logging into from ``matrix.org``
-and instead specify a Homeserver URL of ``https://<server_name>:8448``
-(or just ``https://<server_name>`` if you are using a reverse proxy).
-If you prefer to use another client, refer to our
-`client breakdown <https://matrix.org/docs/projects/clients-matrix>`_.
+Installing prerequisites on Mac OS X::
 
-If all goes well you should at least be able to log in, create a room, and
-start sending messages.
+    xcode-select --install
+    sudo easy_install pip
+    sudo pip install virtualenv
+    
+To install the synapse homeserver run::
 
-.. _`client-user-reg`:
+    virtualenv -p python2.7 ~/.synapse
+    source ~/.synapse/bin/activate
+    pip install --process-dependency-links https://github.com/matrix-org/synapse/tarball/master
 
-Registering a new user from a client
-------------------------------------
+This installs synapse, along with the libraries it uses, into a virtual
+environment under ``~/.synapse``.  Feel free to pick a different directory
+if you prefer.
 
-By default, registration of new users via Matrix clients is disabled. To enable
-it, specify ``enable_registration: true`` in ``homeserver.yaml``. (It is then
-recommended to also set up CAPTCHA - see `<docs/CAPTCHA_SETUP.md>`_.)
+In case of problems, please see the _Troubleshooting section below.
 
-Once ``enable_registration`` is set to ``true``, it is possible to register a
-user via a Matrix client.
+Alternatively, Silvio Fricke has contributed a Dockerfile to automate the
+above in Docker at https://registry.hub.docker.com/u/silviof/docker-matrix/.
 
-Your new user name will be formed partly from the ``server_name``, and partly
-from a localpart you specify when you create the account. Your name will take
-the form of::
+To set up your homeserver, run (in your virtualenv, as before)::
 
-    @localpart:my.domain.name
+    cd ~/.synapse
+    python -m synapse.app.homeserver \
+        --server-name machine.my.domain.name \
+        --config-path homeserver.yaml \
+        --generate-config
 
-(pronounced "at localpart on my dot domain dot name").
+Substituting your host and domain name as appropriate.
 
-As when logging in, you will need to specify a "Custom server".  Specify your
-desired ``localpart`` in the 'User name' box.
+This will generate you a config file that you can then customise, but it will
+also generate a set of keys for you. These keys will allow your Home Server to
+identify itself to other Home Servers, so don't lose or delete them. It would be
+wise to back them up somewhere safe. If, for whatever reason, you do need to
+change your Home Server's keys, you may find that other Home Servers have the
+old key cached. If you update the signing key, you should change the name of the
+key in the <server name>.signing.key file (the second word, which by default is
+, 'auto') to something different.
 
-ACME setup
-==========
+By default, registration of new users is disabled. You can either enable
+registration in the config by specifying ``enable_registration: true``
+(it is then recommended to also set up CAPTCHA), or
+you can use the command line to register new users::
 
-For details on having Synapse manage your federation TLS certificates
-automatically, please see `<docs/ACME.md>`_.

-
-Security Note
-=============
-
-Matrix serves raw user generated data in some APIs - specifically the `content
-repository endpoints <https://matrix.org/docs/spec/client_server/latest.html#get-matrix-media-r0-download-servername-mediaid>`_.
-
-Whilst we have tried to mitigate against possible XSS attacks (e.g.
-https://github.com/matrix-org/synapse/pull/1021) we recommend running
-matrix homeservers on a dedicated domain name, to limit any malicious user generated
-content served to web browsers a matrix API from being able to attack webapps hosted
-on the same domain.  This is particularly true of sharing a matrix webclient and
-server on the same domain.
-
-See https://github.com/vector-im/riot-web/issues/1977 and
-https://developer.github.com/changes/2014-04-25-user-content-security for more details.
-
-
-Upgrading an existing Synapse
-=============================
-
-The instructions for upgrading synapse are in `UPGRADE.rst`_.
-Please check these instructions as upgrading may require extra steps for some
-versions of synapse.
-
-.. _UPGRADE.rst: UPGRADE.rst
-
-.. _reverse-proxy:
-
-Using a reverse proxy with Synapse
-==================================
-
-It is recommended to put a reverse proxy such as
-`nginx <https://nginx.org/en/docs/http/ngx_http_proxy_module.html>`_,
-`Apache <https://httpd.apache.org/docs/current/mod/mod_proxy_http.html>`_,
-`Caddy <https://caddyserver.com/docs/quick-starts/reverse-proxy>`_ or
-`HAProxy <https://www.haproxy.org/>`_ in front of Synapse. One advantage of
-doing so is that it means that you can expose the default https port (443) to
-Matrix clients without needing to run Synapse with root privileges.
-
-For information on configuring one, see `<docs/reverse_proxy.md>`_.
-
-Identity Servers
-================
-
-Identity servers have the job of mapping email addresses and other 3rd Party
-IDs (3PIDs) to Matrix user IDs, as well as verifying the ownership of 3PIDs
-before creating that mapping.
-
-**They are not where accounts or credentials are stored - these live on home
-servers. Identity Servers are just for mapping 3rd party IDs to matrix IDs.**
-
-This process is very security-sensitive, as there is obvious risk of spam if it
-is too easy to sign up for Matrix accounts or harvest 3PID data. In the longer
-term, we hope to create a decentralised system to manage it (`matrix-doc #712
-<https://github.com/matrix-org/matrix-doc/issues/712>`_), but in the meantime,
-the role of managing trusted identity in the Matrix ecosystem is farmed out to
-a cluster of known trusted ecosystem partners, who run 'Matrix Identity
-Servers' such as `Sydent <https://github.com/matrix-org/sydent>`_, whose role
-is purely to authenticate and track 3PID logins and publish end-user public
-keys.
-
-You can host your own copy of Sydent, but this will prevent you reaching other
-users in the Matrix ecosystem via their email address, and prevent them finding
-you. We therefore recommend that you use one of the centralised identity servers
-at ``https://matrix.org`` or ``https://vector.im`` for now.
-
-To reiterate: the Identity server will only be used if you choose to associate
-an email address with your account, or send an invite to another user via their
-email address.
-
-
-Password reset
-==============
-
-Users can reset their password through their client. Alternatively, a server admin
-can reset a users password using the `admin API <docs/admin_api/user_admin_api.rst#reset-password>`_
-or by directly editing the database as shown below.
-
-First calculate the hash of the new password::
-
-    $ ~/synapse/env/bin/hash_password
+    $ source ~/.synapse/bin/activate
+    $ register_new_matrix_user -c homeserver.yaml https://localhost:8448
+    New user localpart: erikj
     Password:
     Confirm password:
-    $2a$12$xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
+    Success!
 
-Then update the ``users`` table in the database::
+For reliable VoIP calls to be routed via this homeserver, you MUST configure
+a TURN server.  See docs/turn-howto.rst for details.
 
-    UPDATE users SET password_hash='$2a$12$xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
-        WHERE name='@test:test.com';
+Using PostgreSQL
+================
 
+As of Synapse 0.9, `PostgreSQL <http://www.postgresql.org>`_ is supported as an
+alternative to the `SQLite <http://sqlite.org/>`_ database that Synapse has
+traditionally used for convenience and simplicity.
+
+The advantages of Postgres include:
+
+ * significant performance improvements due to the superior threading and
+   caching model, smarter query optimiser
+ * allowing the DB to be run on separate hardware
+ * allowing basic active/backup high-availability with a "hot spare" synapse
+   pointing at the same DB master, as well as enabling DB replication in
+   synapse itself.
+   
+The only disadvantage is that the code is relatively new as of April 2015 and
+may have a few regressions relative to SQLite.
+
+For information on how to install and use PostgreSQL, please see
+`docs/postgres.rst <docs/postgres.rst>`_.
+
+Running Synapse
+===============
+
+To actually run your new homeserver, pick a working directory for Synapse to run 
+(e.g. ``~/.synapse``), and::
+
+    cd ~/.synapse
+    source ./bin/activate
+    synctl start
+
+Platform Specific Instructions
+==============================
+
+ArchLinux
+---------
+
+The quickest way to get up and running with ArchLinux is probably with Ivan
+Shapovalov's AUR package from
+https://aur.archlinux.org/packages/matrix-synapse/, which should pull in all
+the necessary dependencies.
+
+Alternatively, to install using pip a few changes may be needed as ArchLinux
+defaults to python 3, but synapse currently assumes python 2.7 by default:
+
+pip may be outdated (6.0.7-1 and needs to be upgraded to 6.0.8-1 )::
+
+    sudo pip2.7 install --upgrade pip
+    
+You also may need to explicitly specify python 2.7 again during the install
+request::
+
+    pip2.7 install --process-dependency-links \
+        https://github.com/matrix-org/synapse/tarball/master
+    
+If you encounter an error with lib bcrypt causing an Wrong ELF Class:
+ELFCLASS32 (x64 Systems), you may need to reinstall py-bcrypt to correctly
+compile it under the right architecture. (This should not be needed if
+installing under virtualenv)::
+
+    sudo pip2.7 uninstall py-bcrypt
+    sudo pip2.7 install py-bcrypt
+    
+During setup of Synapse you need to call python2.7 directly again::
+
+    cd ~/.synapse
+    python2.7 -m synapse.app.homeserver \
+      --server-name machine.my.domain.name \
+      --config-path homeserver.yaml \
+      --generate-config
+        
+...substituting your host and domain name as appropriate.
+
+Windows Install
+---------------
+Synapse can be installed on Cygwin. It requires the following Cygwin packages:
+
+ - gcc
+ - git
+ - libffi-devel
+ - openssl (and openssl-devel, python-openssl)
+ - python
+ - python-setuptools
+
+The content repository requires additional packages and will be unable to process
+uploads without them:
+ - libjpeg8
+ - libjpeg8-devel
+ - zlib
+If you choose to install Synapse without these packages, you will need to reinstall
+``pillow`` for changes to be applied, e.g. ``pip uninstall pillow`` ``pip install
+pillow --user``
+
+Troubleshooting:
+
+- You may need to upgrade ``setuptools`` to get this to work correctly:
+  ``pip install setuptools --upgrade``.
+- You may encounter errors indicating that ``ffi.h`` is missing, even with
+  ``libffi-devel`` installed. If you do, copy the ``.h`` files:
+  ``cp /usr/lib/libffi-3.0.13/include/*.h /usr/include``
+- You may need to install libsodium from source in order to install PyNacl. If
+  you do, you may need to create a symlink to ``libsodium.a`` so ``ld`` can find
+  it: ``ln -s /usr/local/lib/libsodium.a /usr/lib/libsodium.a``
+
+Troubleshooting
+===============
+
+Troubleshooting Installation
+----------------------------
+
+Synapse requires pip 1.7 or later, so if your OS provides too old a version and 
+you get errors about ``error: no such option: --process-dependency-links`` you 
+may need to manually upgrade it::
+
+    sudo pip install --upgrade pip
+
+If pip crashes mid-installation for reason (e.g. lost terminal), pip may
+refuse to run until you remove the temporary installation directory it
+created. To reset the installation::
+
+    rm -rf /tmp/pip_install_matrix
+
+pip seems to leak *lots* of memory during installation.  For instance, a Linux 
+host with 512MB of RAM may run out of memory whilst installing Twisted.  If this 
+happens, you will have to individually install the dependencies which are 
+failing, e.g.::
+
+    pip install twisted

+
+Troubleshooting Running
+-----------------------
+
+If synapse fails with ``missing "sodium.h"`` crypto errors, you may need 
+to manually upgrade PyNaCL, as synapse uses NaCl (http://nacl.cr.yp.to/) for 
+encryption and digital signatures.
+Unfortunately PyNACL currently has a few issues
+(https://github.com/pyca/pynacl/issues/53) and
+(https://github.com/pyca/pynacl/issues/79) that mean it may not install
+correctly, causing all tests to fail with errors about missing "sodium.h". To
+fix try re-installing from PyPI or directly from
+(https://github.com/pyca/pynacl)::
+
+    # Install from PyPI
+    pip install --user --upgrade --force pynacl
+    
+    # Install from github
+    pip install --user https://github.com/pyca/pynacl/tarball/master
+

+
+If running `$ synctl start` fails with 'returned non-zero exit status 1',

+    
+...or by editing synctl with the correct python executable.

 =============================
 
-Synapse is accompanied by `SyTest <https://github.com/matrix-org/sytest>`_,
-a Matrix homeserver integration testing suite, which uses HTTP requests to
-access the API as a Matrix client would. It is able to run Synapse directly from
-the source tree, so installation of the server is not required.
+IMPORTANT: Before upgrading an existing synapse to a new version, please
+refer to UPGRADE.rst for any additional instructions.
 
-Testing with SyTest is recommended for verifying that changes related to the
-Client-Server API are functioning correctly. See the `installation instructions
-<https://github.com/matrix-org/sytest#installing>`_ for details.
+Otherwise, simply re-install the new codebase over the current one - e.g.
+by ``pip install --process-dependency-links
+https://github.com/matrix-org/synapse/tarball/master``
+if using pip, or by ``git pull`` if running off a git working copy.

+Setting up Federation
+=====================
 
-Running out of File Handles
----------------------------
+In order for other homeservers to send messages to your server, it will need to
+be publicly visible on the internet, and they will need to know its host name.
+You have two choices here, which will influence the form of your Matrix user
+IDs:
 
-If synapse runs out of file handles, it typically fails badly - live-locking
-at 100% CPU, and/or failing to accept new TCP connections (blocking the
-connecting client).  Matrix currently can legitimately use a lot of file handles,
-thanks to busy rooms like #matrix:matrix.org containing hundreds of participating
-servers.  The first time a server talks in a room it will try to connect
-simultaneously to all participating servers, which could exhaust the available
-file descriptors between DNS queries & HTTPS sockets, especially if DNS is slow
-to respond. (We need to improve the routing algorithm used to be better than
-full mesh, but as of March 2019 this hasn't happened yet).
+1) Use the machine's own hostname as available on public DNS in the form of
+   its A or AAAA records. This is easier to set up initially, perhaps for
+   testing, but lacks the flexibility of SRV.
 
-If you hit this failure mode, we recommend increasing the maximum number of
-open file handles to be at least 4096 (assuming a default of 1024 or 256).
-This is typically done by editing ``/etc/security/limits.conf``
+2) Set up a SRV record for your domain name. This requires you create a SRV
+   record in DNS, but gives the flexibility to run the server on your own
+   choice of TCP port, on a machine that might not be the same name as the
+   domain name.
 
-Separately, Synapse may leak file handles if inbound HTTP requests get stuck
-during processing - e.g. blocked behind a lock or talking to a remote server etc.
-This is best diagnosed by matching up the 'Received request' and 'Processed request'
-log lines and looking for any 'Processed request' lines which take more than
-a few seconds to execute. Please let us know at #synapse:matrix.org if
-you see this failure mode so we can help debug it, however.
+For the first form, simply pass the required hostname (of the machine) as the
+--server-name parameter::
 
-Help!! Synapse is slow and eats all my RAM/CPU!
------------------------------------------------
+    python -m synapse.app.homeserver \
+        --server-name machine.my.domain.name \
+        --config-path homeserver.yaml \
+        --generate-config
+    python -m synapse.app.homeserver --config-path homeserver.yaml
 
-First, ensure you are running the latest version of Synapse, using Python 3
-with a PostgreSQL database.
+Alternatively, you can run ``synctl start`` to guide you through the process.
 
-Synapse's architecture is quite RAM hungry currently - we deliberately
-cache a lot of recent room data and metadata in RAM in order to speed up
-common requests. We'll improve this in the future, but for now the easiest
-way to either reduce the RAM usage (at the risk of slowing things down)
-is to set the almost-undocumented ``SYNAPSE_CACHE_FACTOR`` environment
-variable. The default is 0.5, which can be decreased to reduce RAM usage
-in memory constrained enviroments, or increased if performance starts to
-degrade.
+For the second form, first create your SRV record and publish it in DNS. This
+needs to be named _matrix._tcp.YOURDOMAIN, and point at at least one hostname
+and port where the server is running.  (At the current time synapse does not
+support clustering multiple servers into a single logical homeserver).  The DNS
+record would then look something like::
 
-However, degraded performance due to a low cache factor, common on
-machines with slow disks, often leads to explosions in memory use due
-backlogged requests. In this case, reducing the cache factor will make
-things worse. Instead, try increasing it drastically. 2.0 is a good
-starting value.
+    $ dig -t srv _matrix._tcp.machine.my.domain.name
+    _matrix._tcp    IN      SRV     10 0 8448 machine.my.domain.name.
 
-Using `libjemalloc <http://jemalloc.net/>`_ can also yield a significant
-improvement in overall memory use, and especially in terms of giving back
-RAM to the OS. To use it, the library must simply be put in the
-LD_PRELOAD environment variable when launching Synapse. On Debian, this
-can be done by installing the ``libjemalloc1`` package and adding this
-line to ``/etc/default/matrix-synapse``::
 
-    LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libjemalloc.so.1
+At this point, you should then run the homeserver with the hostname of this
+SRV record, as that is the name other machines will expect it to have::
 
-This can make a significant difference on Python 2.7 - it's unclear how
-much of an improvement it provides on Python 3.x.
+    python -m synapse.app.homeserver \
+        --server-name YOURDOMAIN \
+        --config-path homeserver.yaml \
+        --generate-config
+    python -m synapse.app.homeserver --config-path homeserver.yaml
 
-If you're encountering high CPU use by the Synapse process itself, you
-may be affected by a bug with presence tracking that leads to a
-massive excess of outgoing federation requests (see `discussion
-<https://github.com/matrix-org/synapse/issues/3971>`_). If metrics
-indicate that your server is also issuing far more outgoing federation
-requests than can be accounted for by your users' activity, this is a
-likely cause. The misbehavior can be worked around by setting
-``use_presence: false`` in the Synapse config file.
 
-People can't accept room invitations from me
---------------------------------------------
+You may additionally want to pass one or more "-v" options, in order to
+increase the verbosity of logging output; at least for initial testing.
 
-The typical failure mode here is that you send an invitation to someone 
-to join a room or direct chat, but when they go to accept it, they get an
-error (typically along the lines of "Invalid signature"). They might see
-something like the following in their logs::

+Identity Servers
+================
+
+The job of authenticating 3PIDs and tracking which 3PIDs are associated with a
+given Matrix user is very security-sensitive, as there is obvious risk of spam
+if it is too easy to sign up for Matrix accounts or harvest 3PID data.
+Meanwhile the job of publishing the end-to-end encryption public keys for
+Matrix users is also very security-sensitive for similar reasons.
+
+Therefore the role of managing trusted identity in the Matrix ecosystem is
+farmed out to a cluster of known trusted ecosystem partners, who run 'Matrix
+Identity Servers' such as ``sydent``, whose role is purely to authenticate and
+track 3PID logins and publish end-user public keys.
+
+It's currently early days for identity servers as Matrix is not yet using 3PIDs
+as the primary means of identity and E2E encryption is not complete. As such,
+we are running a single identity server (https://matrix.org) at the current
+time.

-Upgrading Synapse
-=================
-
-Before upgrading check if any special steps are required to upgrade from the
-version you currently have installed to the current version of Synapse. The extra
-instructions that may be required are listed later in this document.
-
-* If Synapse was installed using `prebuilt packages
-  <INSTALL.md#prebuilt-packages>`_, you will need to follow the normal process
-  for upgrading those packages.
-
-* If Synapse was installed from source, then:
-
-  1. Activate the virtualenv before upgrading. For example, if Synapse is
-     installed in a virtualenv in ``~/synapse/env`` then run:
-
-     .. code:: bash
-
-       source ~/synapse/env/bin/activate
-
-  2. If Synapse was installed using pip then upgrade to the latest version by
-     running:
-
-     .. code:: bash
-
-       pip install --upgrade matrix-synapse
-
-     If Synapse was installed using git then upgrade to the latest version by
-     running:
-
-     .. code:: bash
-
-       git pull
-       pip install --upgrade .
-
-  3. Restart Synapse:
-
-     .. code:: bash
-
-       ./synctl restart
-
-To check whether your update was successful, you can check the running server
-version with:
-
-.. code:: bash
-
-    # you may need to replace 'localhost:8008' if synapse is not configured
-    # to listen on port 8008.
-
-    curl http://localhost:8008/_synapse/admin/v1/server_version
-
-Rolling back to older versions
-------------------------------
-
-Rolling back to previous releases can be difficult, due to database schema
-changes between releases. Where we have been able to test the rollback process,
-this will be noted below.
-
-In general, you will need to undo any changes made during the upgrade process,
-for example:
-
-* pip:
-
-  .. code:: bash
-
-     source env/bin/activate
-     # replace `1.3.0` accordingly:
-     pip install matrix-synapse==1.3.0
-
-* Debian:
-
-  .. code:: bash
-
-     # replace `1.3.0` and `stretch` accordingly:
-     wget https://packages.matrix.org/debian/pool/main/m/matrix-synapse-py3/matrix-synapse-py3_1.3.0+stretch1_amd64.deb
-     dpkg -i matrix-synapse-py3_1.3.0+stretch1_amd64.deb
-
-Upgrading to v1.22.0
-====================
-
-ThirdPartyEventRules breaking changes
--------------------------------------
-
-This release introduces a backwards-incompatible change to modules making use of
-``ThirdPartyEventRules`` in Synapse. If you make use of a module defined under the
-``third_party_event_rules`` config option, please make sure it is updated to handle
-the below change:
-
-The ``http_client`` argument is no longer passed to modules as they are initialised. Instead,
-modules are expected to make use of the ``http_client`` property on the ``ModuleApi`` class.
-Modules are now passed a ``module_api`` argument during initialisation, which is an instance of
-``ModuleApi``. ``ModuleApi`` instances have a ``http_client`` property which acts the same as
-the ``http_client`` argument previously passed to ``ThirdPartyEventRules`` modules.
-
-Upgrading to v1.21.0
-====================
-
-Forwarding ``/_synapse/client`` through your reverse proxy
-----------------------------------------------------------
-
-The `reverse proxy documentation
-<https://github.com/matrix-org/synapse/blob/develop/docs/reverse_proxy.md>`_ has been updated
-to include reverse proxy directives for ``/_synapse/client/*`` endpoints. As the user password
-reset flow now uses endpoints under this prefix, **you must update your reverse proxy
-configurations for user password reset to work**.
-
-Additionally, note that the `Synapse worker documentation
-<https://github.com/matrix-org/synapse/blob/develop/docs/workers.md>`_ has been updated to
- state that the ``/_synapse/client/password_reset/email/submit_token`` endpoint can be handled
-by all workers. If you make use of Synapse's worker feature, please update your reverse proxy
-configuration to reflect this change.
-
-New HTML templates
-------------------
-
-A new HTML template,
-`password_reset_confirmation.html <https://github.com/matrix-org/synapse/blob/develop/synapse/res/templates/password_reset_confirmation.html>`_,
-has been added to the ``synapse/res/templates`` directory. If you are using a
-custom template directory, you may want to copy the template over and modify it.
-
-Note that as of v1.20.0, templates do not need to be included in custom template
-directories for Synapse to start. The default templates will be used if a custom
-template cannot be found.
-
-This page will appear to the user after clicking a password reset link that has
-been emailed to them.
-
-To complete password reset, the page must include a way to make a `POST`
-request to
-``/_synapse/client/password_reset/{medium}/submit_token``
-with the query parameters from the original link, presented as a URL-encoded form. See the file
-itself for more details.
-
-Updated Single Sign-on HTML Templates
--------------------------------------
-
-The ``saml_error.html`` template was removed from Synapse and replaced with the
-``sso_error.html`` template. If your Synapse is configured to use SAML and a
-custom ``sso_redirect_confirm_template_dir`` configuration then any customisations
-of the ``saml_error.html`` template will need to be merged into the ``sso_error.html``
-template. These templates are similar, but the parameters are slightly different:
-
-* The ``msg`` parameter should be renamed to ``error_description``.
-* There is no longer a ``code`` parameter for the response code.
-* A string ``error`` parameter is available that includes a short hint of why a
-  user is seeing the error page.
-
-Upgrading to v1.18.0
-====================
-
-Docker `-py3` suffix will be removed in future versions
--------------------------------------------------------
-
-From 10th August 2020, we will no longer publish Docker images with the `-py3` tag suffix. The images tagged with the `-py3` suffix have been identical to the non-suffixed tags since release 0.99.0, and the suffix is obsolete.
-
-On 10th August, we will remove the `latest-py3` tag. Existing per-release tags (such as `v1.18.0-py3`) will not be removed, but no new `-py3` tags will be added.
-
-Scripts relying on the `-py3` suffix will need to be updated.
-
-Redis replication is now recommended in lieu of TCP replication
----------------------------------------------------------------
-
-When setting up worker processes, we now recommend the use of a Redis server for replication. **The old direct TCP connection method is deprecated and will be removed in a future release.**
-See `docs/workers.md <docs/workers.md>`_ for more details.
-
-Upgrading to v1.14.0
-====================
-
-This version includes a database update which is run as part of the upgrade,
-and which may take a couple of minutes in the case of a large server. Synapse
-will not respond to HTTP requests while this update is taking place.
-
-Upgrading to v1.13.0
-====================
-
-Incorrect database migration in old synapse versions
-----------------------------------------------------
-
-A bug was introduced in Synapse 1.4.0 which could cause the room directory to
-be incomplete or empty if Synapse was upgraded directly from v1.2.1 or
-earlier, to versions between v1.4.0 and v1.12.x.
-
-This will *not* be a problem for Synapse installations which were:
- * created at v1.4.0 or later,
- * upgraded via v1.3.x, or
- * upgraded straight from v1.2.1 or earlier to v1.13.0 or later.
-
-If completeness of the room directory is a concern, installations which are
-affected can be repaired as follows:
-
-1. Run the following sql from a `psql` or `sqlite3` console:
-
-   .. code:: sql
-
-     INSERT INTO background_updates (update_name, progress_json, depends_on) VALUES
-        ('populate_stats_process_rooms', '{}', 'current_state_events_membership');
-
-     INSERT INTO background_updates (update_name, progress_json, depends_on) VALUES
-        ('populate_stats_process_users', '{}', 'populate_stats_process_rooms');
-
-2. Restart synapse.
-
-New Single Sign-on HTML Templates
----------------------------------
-
-New templates (``sso_auth_confirm.html``, ``sso_auth_success.html``, and
-``sso_account_deactivated.html``) were added to Synapse. If your Synapse is
-configured to use SSO and a custom  ``sso_redirect_confirm_template_dir``
-configuration then these templates will need to be copied from
-`synapse/res/templates <synapse/res/templates>`_ into that directory.
-
-Synapse SSO Plugins Method Deprecation
---------------------------------------
-
-Plugins using the ``complete_sso_login`` method of
-``synapse.module_api.ModuleApi`` should update to using the async/await
-version ``complete_sso_login_async`` which includes additional checks. The
-non-async version is considered deprecated.
-
-Rolling back to v1.12.4 after a failed upgrade
-----------------------------------------------
-
-v1.13.0 includes a lot of large changes. If something problematic occurs, you
-may want to roll-back to a previous version of Synapse. Because v1.13.0 also
-includes a new database schema version, reverting that version is also required
-alongside the generic rollback instructions mentioned above. In short, to roll
-back to v1.12.4 you need to:
-
-1. Stop the server
-2. Decrease the schema version in the database:
-
-   .. code:: sql
-
-      UPDATE schema_version SET version = 57;
-
-3. Downgrade Synapse by following the instructions for your installation method
-   in the "Rolling back to older versions" section above.
-
-
-Upgrading to v1.12.0
-====================
-
-This version includes a database update which is run as part of the upgrade,
-and which may take some time (several hours in the case of a large
-server). Synapse will not respond to HTTP requests while this update is taking
-place.
-
-This is only likely to be a problem in the case of a server which is
-participating in many rooms.
-
-0. As with all upgrades, it is recommended that you have a recent backup of
-   your database which can be used for recovery in the event of any problems.
-
-1. As an initial check to see if you will be affected, you can try running the
-   following query from the `psql` or `sqlite3` console. It is safe to run it
-   while Synapse is still running.
-
-   .. code:: sql
-
-      SELECT MAX(q.v) FROM (
-        SELECT (
-          SELECT ej.json AS v
-          FROM state_events se INNER JOIN event_json ej USING (event_id)
-          WHERE se.room_id=rooms.room_id AND se.type='m.room.create' AND se.state_key=''
-          LIMIT 1
-        ) FROM rooms WHERE rooms.room_version IS NULL
-      ) q;
-
-   This query will take about the same amount of time as the upgrade process: ie,
-   if it takes 5 minutes, then it is likely that Synapse will be unresponsive for
-   5 minutes during the upgrade.
-
-   If you consider an outage of this duration to be acceptable, no further
-   action is necessary and you can simply start Synapse 1.12.0.
-
-   If you would prefer to reduce the downtime, continue with the steps below.
-
-2. The easiest workaround for this issue is to manually
-   create a new index before upgrading. On PostgreSQL, his can be done as follows:
-
-   .. code:: sql
-
-      CREATE INDEX CONCURRENTLY tmp_upgrade_1_12_0_index
-      ON state_events(room_id) WHERE type = 'm.room.create';
-
-   The above query may take some time, but is also safe to run while Synapse is
-   running.
-
-   We assume that no SQLite users have databases large enough to be
-   affected. If you *are* affected, you can run a similar query, omitting the
-   ``CONCURRENTLY`` keyword. Note however that this operation may in itself cause
-   Synapse to stop running for some time. Synapse admins are reminded that
-   `SQLite is not recommended for use outside a test
-   environment <https://github.com/matrix-org/synapse/blob/master/README.rst#using-postgresql>`_.
-
-3. Once the index has been created, the ``SELECT`` query in step 1 above should
-   complete quickly. It is therefore safe to upgrade to Synapse 1.12.0.
-
-4. Once Synapse 1.12.0 has successfully started and is responding to HTTP
-   requests, the temporary index can be removed:
-
-   .. code:: sql
-
-      DROP INDEX tmp_upgrade_1_12_0_index;
-
-Upgrading to v1.10.0
-====================
-
-Synapse will now log a warning on start up if used with a PostgreSQL database
-that has a non-recommended locale set.
-
-See `docs/postgres.md <docs/postgres.md>`_ for details.
-
-
-Upgrading to v1.8.0
-===================
-
-Specifying a ``log_file`` config option will now cause Synapse to refuse to
-start, and should be replaced by with the ``log_config`` option. Support for
-the ``log_file`` option was removed in v1.3.0 and has since had no effect.
-
-
-Upgrading to v1.7.0
-===================
-
-In an attempt to configure Synapse in a privacy preserving way, the default
-behaviours of ``allow_public_rooms_without_auth`` and
-``allow_public_rooms_over_federation`` have been inverted. This means that by
-default, only authenticated users querying the Client/Server API will be able
-to query the room directory, and relatedly that the server will not share
-room directory information with other servers over federation.
-
-If your installation does not explicitly set these settings one way or the other
-and you want either setting to be ``true`` then it will necessary to update
-your homeserver configuration file accordingly.
-
-For more details on the surrounding context see our `explainer
-<https://matrix.org/blog/2019/11/09/avoiding-unwelcome-visitors-on-private-matrix-servers>`_.
-
-
-Upgrading to v1.5.0
-===================
-
-This release includes a database migration which may take several minutes to
-complete if there are a large number (more than a million or so) of entries in
-the ``devices`` table. This is only likely to a be a problem on very large
-installations.
-
-
-Upgrading to v1.4.0
-===================
-
-New custom templates
---------------------
-
-If you have configured a custom template directory with the
-``email.template_dir`` option, be aware that there are new templates regarding
-registration and threepid management (see below) that must be included.
-
-* ``registration.html`` and ``registration.txt``
-* ``registration_success.html`` and ``registration_failure.html``
-* ``add_threepid.html`` and  ``add_threepid.txt``
-* ``add_threepid_failure.html`` and ``add_threepid_success.html``
-
-Synapse will expect these files to exist inside the configured template
-directory, and **will fail to start** if they are absent.
-To view the default templates, see `synapse/res/templates
-<https://github.com/matrix-org/synapse/tree/master/synapse/res/templates>`_.
-
-3pid verification changes
--------------------------
-
-**Note: As of this release, users will be unable to add phone numbers or email
-addresses to their accounts, without changes to the Synapse configuration. This
-includes adding an email address during registration.**
-
-It is possible for a user to associate an email address or phone number
-with their account, for a number of reasons:
-
-* for use when logging in, as an alternative to the user id.
-* in the case of email, as an alternative contact to help with account recovery.
-* in the case of email, to receive notifications of missed messages.
-
-Before an email address or phone number can be added to a user's account,
-or before such an address is used to carry out a password-reset, Synapse must
-confirm the operation with the owner of the email address or phone number.
-It does this by sending an email or text giving the user a link or token to confirm
-receipt. This process is known as '3pid verification'. ('3pid', or 'threepid',
-stands for third-party identifier, and we use it to refer to external
-identifiers such as email addresses and phone numbers.)
-
-Previous versions of Synapse delegated the task of 3pid verification to an
-identity server by default. In most cases this server is ``vector.im`` or
-``matrix.org``.
-
-In Synapse 1.4.0, for security and privacy reasons, the homeserver will no
-longer delegate this task to an identity server by default. Instead,
-the server administrator will need to explicitly decide how they would like the
-verification messages to be sent.
-
-In the medium term, the ``vector.im`` and ``matrix.org`` identity servers will
-disable support for delegated 3pid verification entirely. However, in order to
-ease the transition, they will retain the capability for a limited
-period. Delegated email verification will be disabled on Monday 2nd December
-2019 (giving roughly 2 months notice). Disabling delegated SMS verification
-will follow some time after that once SMS verification support lands in
-Synapse.
-
-Once delegated 3pid verification support has been disabled in the ``vector.im`` and
-``matrix.org`` identity servers, all Synapse versions that depend on those
-instances will be unable to verify email and phone numbers through them. There
-are no imminent plans to remove delegated 3pid verification from Sydent
-generally. (Sydent is the identity server project that backs the ``vector.im`` and
-``matrix.org`` instances).
-
-Email
-~~~~~
-Following upgrade, to continue verifying email (e.g. as part of the
-registration process), admins can either:-
-
-* Configure Synapse to use an email server.
-* Run or choose an identity server which allows delegated email verification
-  and delegate to it.
-
-Configure SMTP in Synapse
-+++++++++++++++++++++++++
-
-To configure an SMTP server for Synapse, modify the configuration section
-headed ``email``, and be sure to have at least the ``smtp_host, smtp_port``
-and ``notif_from`` fields filled out.
-
-You may also need to set ``smtp_user``, ``smtp_pass``, and
-``require_transport_security``.
-
-See the `sample configuration file <docs/sample_config.yaml>`_ for more details
-on these settings.
-
-Delegate email to an identity server
-++++++++++++++++++++++++++++++++++++
-
-Some admins will wish to continue using email verification as part of the
-registration process, but will not immediately have an appropriate SMTP server
-at hand.
-
-To this end, we will continue to support email verification delegation via the
-``vector.im`` and ``matrix.org`` identity servers for two months. Support for
-delegated email verification will be disabled on Monday 2nd December.
-
-The ``account_threepid_delegates`` dictionary defines whether the homeserver
-should delegate an external server (typically an `identity server
-<https://matrix.org/docs/spec/identity_service/r0.2.1>`_) to handle sending
-confirmation messages via email and SMS.
-
-So to delegate email verification, in ``homeserver.yaml``, set
-``account_threepid_delegates.email`` to the base URL of an identity server. For
-example:
-
-.. code:: yaml
-
-   account_threepid_delegates:
-       email: https://example.com     # Delegate email sending to example.com
-
-Note that ``account_threepid_delegates.email`` replaces the deprecated
-``email.trust_identity_server_for_password_resets``: if
-``email.trust_identity_server_for_password_resets`` is set to ``true``, and
-``account_threepid_delegates.email`` is not set, then the first entry in
-``trusted_third_party_id_servers`` will be used as the
-``account_threepid_delegate`` for email. This is to ensure compatibility with
-existing Synapse installs that set up external server handling for these tasks
-before v1.4.0. If ``email.trust_identity_server_for_password_resets`` is
-``true`` and no trusted identity server domains are configured, Synapse will
-report an error and refuse to start.
-
-If ``email.trust_identity_server_for_password_resets`` is ``false`` or absent
-and no ``email`` delegate is configured in ``account_threepid_delegates``,
-then Synapse will send email verification messages itself, using the configured
-SMTP server (see above).
-that type.
-
-Phone numbers
-~~~~~~~~~~~~~
-
-Synapse does not support phone-number verification itself, so the only way to
-maintain the ability for users to add phone numbers to their accounts will be
-by continuing to delegate phone number verification to the ``matrix.org`` and
-``vector.im`` identity servers (or another identity server that supports SMS
-sending).
-
-The ``account_threepid_delegates`` dictionary defines whether the homeserver
-should delegate an external server (typically an `identity server
-<https://matrix.org/docs/spec/identity_service/r0.2.1>`_) to handle sending
-confirmation messages via email and SMS.
-
-So to delegate phone number verification, in ``homeserver.yaml``, set
-``account_threepid_delegates.msisdn`` to the base URL of an identity
-server. For example:
-
-.. code:: yaml
-
-   account_threepid_delegates:
-       msisdn: https://example.com     # Delegate sms sending to example.com
-
-The ``matrix.org`` and ``vector.im`` identity servers will continue to support
-delegated phone number verification via SMS until such time as it is possible
-for admins to configure their servers to perform phone number verification
-directly. More details will follow in a future release.
-
-Rolling back to v1.3.1
-----------------------
-
-If you encounter problems with v1.4.0, it should be possible to roll back to
-v1.3.1, subject to the following:
-
-* The 'room statistics' engine was heavily reworked in this release (see
-  `#5971 <https://github.com/matrix-org/synapse/pull/5971>`_), including
-  significant changes to the database schema, which are not easily
-  reverted. This will cause the room statistics engine to stop updating when
-  you downgrade.
-
-  The room statistics are essentially unused in v1.3.1 (in future versions of
-  Synapse, they will be used to populate the room directory), so there should
-  be no loss of functionality. However, the statistics engine will write errors
-  to the logs, which can be avoided by setting the following in
-  `homeserver.yaml`:
-
-  .. code:: yaml
-
-    stats:
-      enabled: false
-
-  Don't forget to re-enable it when you upgrade again, in preparation for its
-  use in the room directory!
-
-Upgrading to v1.2.0
-===================
-
-Some counter metrics have been renamed, with the old names deprecated. See
-`the metrics documentation <docs/metrics-howto.md#renaming-of-metrics--deprecation-of-old-names-in-12>`_
-for details.
-
-Upgrading to v1.1.0
-===================
-
-Synapse v1.1.0 removes support for older Python and PostgreSQL versions, as
-outlined in `our deprecation notice <https://matrix.org/blog/2019/04/08/synapse-deprecating-postgres-9-4-and-python-2-x>`_.
-
-Minimum Python Version
-----------------------
-
-Synapse v1.1.0 has a minimum Python requirement of Python 3.5. Python 3.6 or
-Python 3.7 are recommended as they have improved internal string handling,
-significantly reducing memory usage.
-
-If you use current versions of the Matrix.org-distributed Debian packages or
-Docker images, action is not required.
-
-If you install Synapse in a Python virtual environment, please see "Upgrading to
-v0.34.0" for notes on setting up a new virtualenv under Python 3.
-
-Minimum PostgreSQL Version
---------------------------
-
-If using PostgreSQL under Synapse, you will need to use PostgreSQL 9.5 or above.
-Please see the
-`PostgreSQL documentation <https://www.postgresql.org/docs/11/upgrading.html>`_
-for more details on upgrading your database.
-
-Upgrading to v1.0
-=================
-
-Validation of TLS certificates
-------------------------------
-
-Synapse v1.0 is the first release to enforce
-validation of TLS certificates for the federation API. It is therefore
-essential that your certificates are correctly configured. See the `FAQ
-<docs/MSC1711_certificates_FAQ.md>`_ for more information.
-
-Note, v1.0 installations will also no longer be able to federate with servers
-that have not correctly configured their certificates.
-
-In rare cases, it may be desirable to disable certificate checking: for
-example, it might be essential to be able to federate with a given legacy
-server in a closed federation. This can be done in one of two ways:-
-
-* Configure the global switch ``federation_verify_certificates`` to ``false``.
-* Configure a whitelist of server domains to trust via ``federation_certificate_verification_whitelist``.
-
-See the `sample configuration file <docs/sample_config.yaml>`_
-for more details on these settings.
-
-Email
------
-When a user requests a password reset, Synapse will send an email to the
-user to confirm the request.
-
-Previous versions of Synapse delegated the job of sending this email to an
-identity server. If the identity server was somehow malicious or became
-compromised, it would be theoretically possible to hijack an account through
-this means.
-
-Therefore, by default, Synapse v1.0 will send the confirmation email itself. If
-Synapse is not configured with an SMTP server, password reset via email will be
-disabled.
-
-To configure an SMTP server for Synapse, modify the configuration section
-headed ``email``, and be sure to have at least the ``smtp_host``, ``smtp_port``
-and ``notif_from`` fields filled out. You may also need to set ``smtp_user``,
-``smtp_pass``, and ``require_transport_security``.
-
-If you are absolutely certain that you wish to continue using an identity
-server for password resets, set ``trust_identity_server_for_password_resets`` to ``true``.
-
-See the `sample configuration file <docs/sample_config.yaml>`_
-for more details on these settings.
-
-New email templates
----------------
-Some new templates have been added to the default template directory for the purpose of the
-homeserver sending its own password reset emails. If you have configured a custom
-``template_dir`` in your Synapse config, these files will need to be added.
-
-``password_reset.html`` and ``password_reset.txt`` are HTML and plain text templates
-respectively that contain the contents of what will be emailed to the user upon attempting to
-reset their password via email. ``password_reset_success.html`` and
-``password_reset_failure.html`` are HTML files that the content of which (assuming no redirect
-URL is set) will be shown to the user after they attempt to click the link in the email sent
-to them.
-
-Upgrading to v0.99.0
-====================
-
-Please be aware that, before Synapse v1.0 is released around March 2019, you
-will need to replace any self-signed certificates with those verified by a
-root CA. Information on how to do so can be found at `the ACME docs
-<docs/ACME.md>`_.
-
-For more information on configuring TLS certificates see the `FAQ <docs/MSC1711_certificates_FAQ.md>`_.
-
-Upgrading to v0.34.0
-====================
-
-1. This release is the first to fully support Python 3. Synapse will now run on
-   Python versions 3.5, or 3.6 (as well as 2.7). We recommend switching to
-   Python 3, as it has been shown to give performance improvements.
-
-   For users who have installed Synapse into a virtualenv, we recommend doing
-   this by creating a new virtualenv. For example::
-
-       virtualenv -p python3 ~/synapse/env3
-       source ~/synapse/env3/bin/activate
-       pip install matrix-synapse
-
-   You can then start synapse as normal, having activated the new virtualenv::
-
-       cd ~/synapse
-       source env3/bin/activate
-       synctl start
-
-   Users who have installed from distribution packages should see the relevant
-   package documentation. See below for notes on Debian packages.
-
-   * When upgrading to Python 3, you **must** make sure that your log files are
-     configured as UTF-8, by adding ``encoding: utf8`` to the
-     ``RotatingFileHandler`` configuration (if you have one) in your
-     ``<server>.log.config`` file. For example, if your ``log.config`` file
-     contains::
-
-       handlers:
-         file:
-           class: logging.handlers.RotatingFileHandler
-           formatter: precise
-           filename: homeserver.log
-           maxBytes: 104857600
-           backupCount: 10
-           filters: [context]
-         console:
-           class: logging.StreamHandler
-           formatter: precise
-           filters: [context]
-
-     Then you should update this to be::
-
-       handlers:
-         file:
-           class: logging.handlers.RotatingFileHandler
-           formatter: precise
-           filename: homeserver.log
-           maxBytes: 104857600
-           backupCount: 10
-           filters: [context]
-           encoding: utf8
-         console:
-           class: logging.StreamHandler
-           formatter: precise
-           filters: [context]
-
-     There is no need to revert this change if downgrading to Python 2.
-
-   We are also making available Debian packages which will run Synapse on
-   Python 3. You can switch to these packages with ``apt-get install
-   matrix-synapse-py3``, however, please read `debian/NEWS
-   <https://github.com/matrix-org/synapse/blob/release-v0.34.0/debian/NEWS>`_
-   before doing so. The existing ``matrix-synapse`` packages will continue to
-   use Python 2 for the time being.
-
-2. This release removes the ``riot.im`` from the default list of trusted
-   identity servers.
-
-   If ``riot.im`` is in your homeserver's list of
-   ``trusted_third_party_id_servers``, you should remove it. It was added in
-   case a hypothetical future identity server was put there. If you don't
-   remove it, users may be unable to deactivate their accounts.
-
-3. This release no longer installs the (unmaintained) Matrix Console web client
-   as part of the default installation. It is possible to re-enable it by
-   installing it separately and setting the ``web_client_location`` config
-   option, but please consider switching to another client.
-
-Upgrading to v0.33.7
-====================
-
-This release removes the example email notification templates from
-``res/templates`` (they are now internal to the python package). This should
-only affect you if you (a) deploy your Synapse instance from a git checkout or
-a github snapshot URL, and (b) have email notifications enabled.
-
-If you have email notifications enabled, you should ensure that
-``email.template_dir`` is either configured to point at a directory where you
-have installed customised templates, or leave it unset to use the default
-templates.
-
-Upgrading to v0.27.3
-====================
-
-This release expands the anonymous usage stats sent if the opt-in
-``report_stats`` configuration is set to ``true``. We now capture RSS memory
-and cpu use at a very coarse level. This requires administrators to install
-the optional ``psutil`` python module.
-
-We would appreciate it if you could assist by ensuring this module is available
-and ``report_stats`` is enabled. This will let us see if performance changes to
-synapse are having an impact to the general community.
-
-Upgrading to v0.15.0
-====================
-
-If you want to use the new URL previewing API (/_matrix/media/r0/preview_url)
-then you have to explicitly enable it in the config and update your dependencies
-dependencies.  See README.rst for details.
-
-
-Upgrading to v0.11.0
-====================
-
-This release includes the option to send anonymous usage stats to matrix.org,
-and requires that administrators explictly opt in or out by setting the
-``report_stats`` option to either ``true`` or ``false``.
-
-We would really appreciate it if you could help our project out by reporting
-anonymized usage statistics from your homeserver. Only very basic aggregate
-data (e.g. number of users) will be reported, but it helps us to track the
-growth of the Matrix community, and helps us to make Matrix a success, as well
-as to convince other networks that they should peer with us.
