Synapse v0.17.0 is finally here, which includes a couple of security fixes so please upgrade. Other notable new things are:

A bunch of new admin APIs, including purging locally cached data (which has been long requested to help free up disk space). See the docs folder for more details.
Device management APIs in preparation for end to end encryption.
Better support for LDAP authentication, thanks to Martin Weinelt! (This may break existing LDAP configuration, see PR #843 for more details.)
Lots and lots of bug fixes and various bits of performance work.

For a full list of everything that has changed see below or the release page.

I'd also like to thank Will Hunt, Martin Weinelt and Kent Shikama for their contributions!
