Wowzers - our 8th dot release for v0.33!

This time we have a bunch of bug fixes and db performance improvements as well as better support for auto-join rooms and the ability for admins to limit who can create rooms aliases.

v0.33.8 also contains more python 3 fixes: we are running most of matrix.org on python 3 as of right now and seeing some pretty impressive performance improvements. Look out for Hawkowl's write up coming soon.

For those interested in what we are working on right now, take a look at our task board.

As ever, you can get the new update here or any of the sources mentioned at https://github.com/matrix-org/synapse. Note, Synapse is now available from PyPI, pick it up here.
