Synapse 0.33.6 released!

Right folks, time for Synapse 0.33.6.

These past few weeks we've been focusing on fixing a whole host of federation bugs to improve reliability and latency. Additionally we've squashed some py3 bugs, improved lazy loading and been working hard in the background to improve our CI infrastructure. Finally, we cleaned up the Docker file, the image is now half the size of 0.33.5.1's standing at 58 MB.

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.
