+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.
+* Fix bug while generating the error message when a file path specified in

 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.

-   signed correctly.

 Troubleshooting Installation
 ----------------------------
@@ -116,46 +136,100 @@ 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 --user twisted
+    $ pip install twisted
 
 On OSX, if you encounter clang: error: unknown argument: '-mno-fused-madd' you
 will need to export CFLAGS=-Qunused-arguments.
 
+ArchLinux
+---------
+
+Installation on ArchLinux may encounter a few hiccups as Arch 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 homeserver you need to call python2.7 directly again::
+
+    $ 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``
+
 Running Your Homeserver
 =======================
 
 To actually run your new homeserver, pick a working directory for Synapse to run 
 (e.g. ``~/.synapse``), and::
 
-    $ mkdir ~/.synapse
     $ cd ~/.synapse
-    
-    $ # on Linux
-    $ ~/.local/bin/synctl start
-    
-    $ # on OSX
-    $ ~/Library/Python/2.7/bin/synctl start
+    $ source ./bin/activate
+    $ synctl start
 
 Troubleshooting Running
 -----------------------
 
-If ``synctl`` fails with ``pkg_resources.DistributionNotFound`` errors you may 
-need a newer version of setuptools than that provided by your OS.::
-
-    $ sudo pip install setuptools --upgrade
-
 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.

+  sense for their function invocation.  (e.g. if they want to add comments
+  per-argument, or put expressions in the arguments, or group related arguments
+  together, or want to deliberately extend or preserve vertical/horizontal
+  space)
+
+Comments should follow the google code style. This is so that we can generate
+documentation with sphinx (http://sphinxcontrib-napoleon.readthedocs.org/en/latest/) 
+
+Code should pass pep8 --max-line-length=100 without any warnings.

+Media Repository 
+================
+
+*Synapse implementation-specific details for the media repository*
+
+The media repository is where attachments and avatar photos are stored.
+It stores attachment content and thumbnails for media uploaded by local users.
+It caches attachment content and thumbnails for media uploaded by remote users.
+
+Storage
+-------
+
+Each item of media is assigned a ``media_id`` when it is uploaded.
+The ``media_id`` is a randomly chosen, URL safe 24 character string.
+Metadata such as the MIME type, upload time and length are stored in the
+sqlite3 database indexed by ``media_id``.
+Content is stored on the filesystem under a ``"local_content"`` directory.
+Thumbnails are stored under a ``"local_thumbnails"`` directory.
+The item with ``media_id`` ``"aabbccccccccdddddddddddd"`` is stored under
+``"local_content/aa/bb/ccccccccdddddddddddd"``. Its thumbnail with width
+``128`` and height ``96`` and type ``"image/jpeg"`` is stored under
+``"local_thumbnails/aa/bb/ccccccccdddddddddddd/128-96-image-jpeg"``
+Remote content is cached under ``"remote_content"`` directory. Each item of
+remote content is assigned a local "``filesystem_id``" to ensure that the
+directory structure ``"remote_content/server_name/aa/bb/ccccccccdddddddddddd"``
+is appropriate. Thumbnails for remote content are stored under
+``"remote_thumbnails/server_name/..."``
