+Changes in synapse v0.12.0 (2016-01-04)
+=======================================
+
+* Expose ``/login`` under ``r0`` (PR #459)
+
+Changes in synapse v0.12.0-rc3 (2015-12-23)
+===========================================
+
+* Allow guest accounts access to ``/sync`` (PR #455)
+* Allow filters to include/exclude rooms at the room level
+  rather than just from the components of the sync for each
+  room. (PR #454)
+* Include urls for room avatars in the response to ``/publicRooms`` (PR #453)
+* Don't set a identicon as the avatar for a user when they register (PR #450)
+* Add a ``display_name`` to third-party invites (PR #449)
+* Send more information to the identity server for third-party invites so that
+  it can send richer messages to the invitee (PR #446)
+* Cache the responses to ``/initialSync`` for 5 minutes. If a client
+  retries a request to ``/initialSync`` before the a response was computed
+  to the first request then the same response is used for both requests
+  (PR #457)
+* Fix a bug where synapse would always request the signing keys of
+  remote servers even when the key was cached locally (PR #452)
+* Fix 500 when pagination search results (PR #447)
+* Fix a bug where synapse was leaking raw email address in third-party invites
+  (PR #448)
+
+Changes in synapse v0.12.0-rc2 (2015-12-14)
+===========================================
+
+* Add caches for whether rooms have been forgotten by a user (PR #434)
+* Remove instructions to use ``--process-dependency-link`` since all of the
+  dependencies of synapse are on PyPI (PR #436)
+* Parallelise the processing of ``/sync`` requests (PR #437)
+* Fix race updating presence in ``/events`` (PR #444)
+* Fix bug back-populating search results (PR #441)
+* Fix bug calculating state in ``/sync`` requests (PR #442)
+
+Changes in synapse v0.12.0-rc1 (2015-12-10)
+===========================================
+
+* Host the client APIs released as r0 by
+  https://matrix.org/docs/spec/r0.0.0/client_server.html
+  on paths prefixed by ``/_matrix/client/r0``. (PR #430, PR #415, PR #400)
+* Updates the client APIs to match r0 of the matrix specification.
+
+  * All APIs return events in the new event format, old APIs also include
+    the fields needed to parse the event using the old format for
+    compatibility. (PR #402)
+  * Search results are now given as a JSON array rather than
+    a JSON object (PR #405)
+  * Miscellaneous changes to search (PR #403, PR #406, PR #412)
+  * Filter JSON objects may now be passed as query parameters to ``/sync``
+    (PR #431)
+  * Fix implementation of ``/admin/whois`` (PR #418)
+  * Only include the rooms that user has left in ``/sync`` if the client
+    requests them in the filter (PR #423)
+  * Don't push for ``m.room.message`` by default (PR #411)
+  * Add API for setting per account user data (PR #392)
+  * Allow users to forget rooms (PR #385)
+
+* Performance improvements and monitoring:
+
+  * Add per-request counters for CPU time spent on the main python thread.
+    (PR #421, PR #420)
+  * Add per-request counters for time spent in the database (PR #429)
+  * Make state updates in the C+S API idempotent (PR #416)
+  * Only fire ``user_joined_room`` if the user has actually joined. (PR #410)
+  * Reuse a single http client, rather than creating new ones (PR #413)
+
+* Fixed a bug upgrading from older versions of synapse on postgresql (PR #417)
+
+Changes in synapse v0.11.1 (2015-11-20)
+=======================================
+
+* Add extra options to search API (PR #394)
+* Fix bug where we did not correctly cap federation retry timers. This meant it
+  could take several hours for servers to start talking to ressurected servers,
+  even when they were receiving traffic from them (PR #393)
+* Don't advertise login token flow unless CAS is enabled. This caused issues
+  where some clients would always use the fallback API if they did not
+  recognize all login flows (PR #391)
+* Change /v2 sync API to rename ``private_user_data`` to ``account_data``
+  (PR #386)
+* Change /v2 sync API to remove the ``event_map`` and rename keys in ``rooms``
+  object (PR #389)
+

+* Allow UTF-8 filenames for upload. (PR #259)
+
+Changes in synapse v0.10.0-rc3 (2015-08-25)
+===========================================
+
+* Add ``--keys-directory`` config option to specify where files such as
+  certs and signing keys should be stored in, when using ``--generate-config``
+  or ``--generate-keys``. (PR #250)
+* Allow ``--config-path`` to specify a directory, causing synapse to use all
+  \*.yaml files in the directory as config files. (PR #249)

+  or typing events, reducing the CPU cost of each pusher.
+
+
+Changes in synapse v0.10.0-rc1 (2015-08-21)
+===========================================
+
+Also see v0.9.4-rc1 changelog, which has been amalgamated into this release.

+* Add support for new ``m.room.canonical_alias`` event. (PR #233)
+* Change synapse to treat user IDs case insensitively during registration and
+  login. (If two users already exist with case insensitive matching user ids,
+  synapse will continue to require them to specify their user ids exactly.)
+* Error if a user tries to register with an email already in use. (PR #211)
+* Add extra and improve existing caches  (PR #212, #219, #226, #228)
+* Batch various storage request (PR #226, #228)
+* Fix bug where we didn't correctly log the entity that triggered the request
+  if the request came in via an application service (PR #230)
+* Fix bug where we needlessly regenerated the full list of rooms an AS is
+  interested in. (PR #232)
+* Add support for AS's to use v2_alpha registration API (PR #210)
+
+
+Configuration:
+
+* Add ``--generate-keys`` that will generate any missing cert and key files in
+  the configuration files. This is equivalent to running ``--generate-config``
+  on an existing configuration file. (PR #220)
+* ``--generate-config`` now no longer requires a ``--server-name`` parameter
+  when used on existing configuration files. (PR #220)
+* Add ``--print-pidfile`` flag that controls the printing of the pid to stdout
+  of the demonised process. (PR #213)
+
+Media Repository:
+
+* Fix bug where we picked a lower resolution image than requested. (PR #205)
+* Add support for specifying if a the media repository should dynamically
+  thumbnail images or not. (PR #206)

+* Fix starting the demo homeservers without rate-limiting enabled. (PR #182)
+* Fix enabling registration on demo homeservers (PR #223)
+
+
+Changes in synapse v0.9.4-rc1 (2015-07-21)
+==========================================
+
+General:
+
+* Add basic implementation of receipts. (SPEC-99)
+* Add support for configuration presets in room creation API. (PR  #203)

+* Change power level semantics so that you cannot kick, ban or change power
+  levels of users that have equal or greater power level than you. (SYN-192)
+* Improve performance by bulk inserting events where possible. (PR #193)
+* Improve performance by bulk verifying signatures where possible. (PR #194)
+
+
+Configuration:
+
+* Add support for including TLS certificate chains.
+
+Media Repository:
+
+* Add Content-Disposition headers to content repository responses. (SYN-150)
+
+
+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.

+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.

+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 :)

+Conclusion
+~~~~~~~~~~

+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.

+By default, registration of new users is disabled. You can either enable

-Troubleshooting Installation
-----------------------------
+Running Synapse
+===============
 
-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::
+To actually run your new homeserver, pick a working directory for Synapse to
+run (e.g. ``~/.synapse``), and::
 
-    $ sudo pip install --upgrade pip
+    cd ~/.synapse
+    source ./bin/activate
+    synctl start
 
-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::
+Using PostgreSQL
+================
 
-    $ rm -rf /tmp/pip_install_matrix
+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.
 
-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.::
+The advantages of Postgres include:
 
-    $ pip install twisted
+* 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.
 
-On OSX, if you encounter clang: error: unknown argument: '-mno-fused-madd' you
-will need to export CFLAGS=-Qunused-arguments.
+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>`_.
+
+Platform Specific Instructions
+==============================
 
 ArchLinux
 ---------
 
-Installation on ArchLinux may encounter a few hiccups as Arch defaults to
-python 3, but synapse currently assumes python 2.7 by default.
+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
-    
+    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
-    
+    pip2.7 install 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 homeserver you need to call python2.7 directly again::
+    sudo pip2.7 uninstall py-bcrypt
+    sudo pip2.7 install py-bcrypt
 
-    $ cd ~/.synapse
-    $ python2.7 -m synapse.app.homeserver \

+Captcha can be enabled for this home server. This file explains how to do that.
+The captcha mechanism used is Google's ReCaptcha. This requires API keys from Google.
+
+Getting keys
+------------
+Requires a public/private key pair from:
+
+https://developers.google.com/recaptcha/
+
+
+Setting ReCaptcha Keys
+----------------------
+The keys are a config option on the home server config. If they are not 
+visible, you can generate them via --generate-config. Set the following value:
+
+  recaptcha_public_key: YOUR_PUBLIC_KEY
+  recaptcha_private_key: YOUR_PRIVATE_KEY
+  
+In addition, you MUST enable captchas via:
+
+  enable_registration_captcha: true
+
+Configuring IP used for auth
+----------------------------
+The ReCaptcha API requires that the IP address of the user who solved the
+captcha is sent. If the client is connecting through a proxy or load balancer,
+it may be required to use the X-Forwarded-For (XFF) header instead of the origin
+IP address. This can be configured as an option on the home server like so:

+  captcha_ip_origin_is_x_forwarded: true

+Registering an Application Service
+==================================
+
+The registration of new application services depends on the homeserver used. 
+In synapse, you need to create a new configuration file for your AS and add it
+to the list specified under the ``app_service_config_files`` config
+option in your synapse config.
+
+For example:
+
+.. code-block:: yaml
+
+  app_service_config_files:
+  - /home/matrix/.synapse/<your-AS>.yaml
+
+
+The format of the AS configuration file is as follows:

+..  code-block:: yaml
+
+    url: <base url of AS>
+    as_token: <token AS will add to requests to HS>
+    hs_token: <token HS will add to requests to AS>

+How to monitor Synapse metrics using Prometheus
+===============================================
+
+1: Install prometheus:
+  Follow instructions at http://prometheus.io/docs/introduction/install/
+
+2: Enable synapse metrics:
+  Simply setting a (local) port number will enable it. Pick a port.
+  prometheus itself defaults to 9090, so starting just above that for
+  locally monitored services seems reasonable. E.g. 9092:
+
+  Add to homeserver.yaml
+
+    metrics_port: 9092
+
+  Restart synapse
+
+3: Check out synapse-prometheus-config
+  https://github.com/matrix-org/synapse-prometheus-config
+
+4: Add ``synapse.html`` and ``synapse.rules``
+  The ``.html`` file needs to appear in prometheus's ``consoles`` directory,
+  and the ``.rules`` file needs to be invoked somewhere in the main config
+  file. A symlink to each from the git checkout into the prometheus directory
+  might be easiest to ensure ``git pull`` keeps it updated.
+
+5: Add a prometheus target for synapse
+  This is easiest if prometheus runs on the same machine as synapse, as it can
+  then just use localhost::
+
+    global: {
+      rule_file: "synapse.rules"
+    }
+
+    job: {
+      name: "synapse"
+
+      target_group: {
+        target: "http://localhost:9092/"
+      }
+    }
+
+6: Start prometheus::
+
+   ./prometheus -config.file=prometheus.conf
+
+7: Wait a few seconds for it to start and perform the first scrape,
+   then visit the console:

+Using Postgres
+--------------
+
+Set up database
+===============
+
+The PostgreSQL database used *must* have the correct encoding set, otherwise
+would not be able to store UTF8 strings. To create a database with the correct
+encoding use, e.g.::
+
+ CREATE DATABASE synapse
+  ENCODING 'UTF8'
+  LC_COLLATE='C'
+  LC_CTYPE='C'
+  template=template0
+  OWNER synapse_user;
+
+This would create an appropriate database named ``synapse`` owned by the
+``synapse_user`` user (which must already exist).
+
+Set up client in Debian/Ubuntu
+===========================
+
+Postgres support depends on the postgres python connector ``psycopg2``. In the
+virtual env::
+
+    sudo apt-get install libpq-dev
+    pip install psycopg2
+
+Set up client in RHEL/CentOs 7
+==============================
+
+Make sure you have the appropriate version of postgres-devel installed. For a
+postgres 9.4, use the postgres 9.4 packages from
+[here](https://wiki.postgresql.org/wiki/YUM_Installation).
+
+As with Debian/Ubuntu, postgres support depends on the postgres python connector
+``psycopg2``. In the virtual env::
+
+    sudo yum install postgresql-devel libpqxx-devel.x86_64
+    export PATH=/usr/pgsql-9.4/bin/:$PATH
+    pip install psycopg2
+
+Synapse config
+==============
+
+When you are ready to start using PostgreSQL, add the following line to your
+config file::
+
+    database:
+        name: psycopg2
+        args:
+            user: <user>
+            password: <pass>
+            database: <db>
+            host: <host>
+            cp_min: 5
+            cp_max: 10
+
+All key, values in ``args`` are passed to the ``psycopg2.connect(..)``
+function, except keys beginning with ``cp_``, which are consumed by the twisted
+adbapi connection pool.
+
+
+Porting from SQLite
+===================
+
+Overview
+~~~~~~~~
+
+The script ``synapse_port_db`` allows porting an existing synapse server
+backed by SQLite to using PostgreSQL. This is done in as a two phase process:
+
+1. Copy the existing SQLite database to a separate location (while the server
+   is down) and running the port script against that offline database.
+2. Shut down the server. Rerun the port script to port any data that has come
+   in since taking the first snapshot. Restart server against the PostgreSQL
+   database.
+
+The port script is designed to be run repeatedly against newer snapshots of the
+SQLite database file. This makes it safe to repeat step 1 if there was a delay
+between taking the previous snapshot and being ready to do step 2.
+
+It is safe to at any time kill the port script and restart it.
+
+Using the port script
+~~~~~~~~~~~~~~~~~~~~~
+
+Firstly, shut down the currently running synapse server and copy its database
+file (typically ``homeserver.db``) to another location. Once the copy is
+complete, restart synapse.  For instance::
+
+    ./synctl stop
+    cp homeserver.db homeserver.db.snapshot
+    ./synctl start
+
+Assuming your new config file (as described in the section *Synapse config*)
+is named ``homeserver-postgres.yaml`` and the SQLite snapshot is at
+``homeserver.db.snapshot`` then simply run::
+
+    synapse_port_db --sqlite-database homeserver.db.snapshot \
+        --postgres-config homeserver-postgres.yaml
+
+The flag ``--curses`` displays a coloured curses progress UI.
+
+If the script took a long time to complete, or time has otherwise passed since
+the original snapshot was taken, repeat the previous steps with a newer
+snapshot.
+
+To complete the conversion shut down the synapse server and run the port
+script one last time, e.g. if the SQLite database is at  ``homeserver.db``
+run::
+
+    synapse_port_db --sqlite-database homeserver.db \
+        --postgres-config database_config.yaml
+
+Once that has completed, change the synapse config to point at the PostgreSQL
+database configuration file using the ``database_config`` parameter (see
+`Synapse Config`_) and restart synapse. Synapse should now be running against
+PostgreSQL.

+2----ASb[e]->|  Queuer  |

+      |Database|            | Controller |---> SEND TO AS
+      `--------`            +------------+
+What happens on SEND TO AS depends on the state of the Application Service:
+ - If the AS is marked as DOWN, do nothing.
+ - If the AS is marked as UP, send the transaction.
+     * SUCCESS : Increment where the AS is up to txn-wise and nuke the txn
+                 contents from the db.
+     * FAILURE : Marked AS as DOWN and start Recoverer.
+
+Recoverer attempts to recover ASes who have died. The flow for this looks like:
+                ,--------------------- backoff++ --------------.
+               V                                               |
