+Specification changes in v0.2.0 (2015-10-02)
+============================================
+
+This update fundamentally restructures the specification. The specification has
+been split into more digestible "modules" which each describe a particular
+function (e.g. typing). This was done in order make the specification easier to
+maintain and help define which modules are mandatory for certain types
+of clients. Types of clients along with the mandatory modules can be found in a
+new "Feature Profiles" section. This update also begins to aggressively
+standardise on using Swagger and JSON Schema to document HTTP endpoints and
+Events respectively. It also introduces a number of new concepts to Matrix.
+
+Additions:
+ - New section: Feature Profiles.
+ - New section: Receipts.
+ - New section: Room history visibility.
+ - New event: ``m.receipt``.
+ - New event: ``m.room.canonical_alias``
+ - New event: ``m.room.history_visibility``
+ - New keys: ``/createRoom`` - allows room "presets" using ``preset`` and
+   ``initial_state`` keys.
+ - New endpoint: ``/tokenrefresh`` - Related to refreshing access tokens.
+
+Modifications:
+ - Convert most of the older HTTP APIs to Swagger documentation.
+ - Convert most of the older event formats to JSON Schema.
+ - Move selected client-server sections to be "Modules".
