+Changes in synapse 0.6.0 (2014-12-16)
+=====================================
+
+ * Add new API for media upload and download that supports thumbnailing.
+ * 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.

 On OSX, if you encounter clang: error: unknown argument: '-mno-fused-madd' you

+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``

+Upgrading to v0.6.0
+===================
+
+To pull in new dependencies, run::
+
+    python setup.py develop --user
+
+This update includes a change to the database schema. To upgrade you first need
+to upgrade the database by running::
+
+    python scripts/upgrade_db_to_v0.6.0.py <db> <server_name> <signing_key>
+
+Where `<db>` is the location of the database, `<server_name>` is the
+server name as specified in the synapse configuration, and `<signing_key>` is
+the location of the signing key as specified in the synapse configuration.
+
+This may take some time to complete. Failures of signatures and content hashes
+can safely be ignored.

+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/..."``
