Changes in synapse v0.18.0-rc1 (2016-09-16)

===========================================

The release includes major changes to the state storage database schemas, which
significantly reduce database size. Synapse will attempt to upgrade the current
data in the background. Servers with large SQLite database may experience
degradation of performance while this upgrade is in progress, therefore you may
want to consider migrating to using Postgres before upgrading very large SQLite
daabases

Features:

* Add ``only=highlight`` on ``/notifications`` (PR #1081)
* Add server param to /publicRooms (PR #1082)
* Allow clients to ask for the whole of a single state event (PR #1094)
* Add is_direct param to /createRoom (PR #1108)
* Add pagination support to publicRooms (PR #1121)
* Add very basic filter API to /publicRooms (PR #1126)
* Add basic direct to device messaging support for E2E (PR #1074, #1084, #1104,
  #1111)

Changes:

* Move to storing state_groups_state as deltas, greatly reducing DB size (PR
  #1065)
* Reduce amount of state pulled out of the DB during common requests (PR #1069)
* Allow PDF to be rendered from media repo (PR #1071)
* Reindex state_groups_state after pruning (PR #1085)
* Clobber EDUs in send queue (PR #1095)
* Conform better to the CAS protocol specification (PR #1100)
* Limit how often we ask for keys from dead servers (PR #1114)

Bug fixes:
