Synapse 0.34.1rc1 (2019-01-08)

Features
--------

- Special-case a support user for use in verifying behaviour of a given server. The support user does not appear in user directory or monthly active user counts. ([\#4141](https://github.com/matrix-org/synapse/issues/4141), [\#4344](https://github.com/matrix-org/synapse/issues/4344))

- Synapse can now have its conditional/extra dependencies installed by pip.

If you want to install all optional dependencies, you can use "all" instead.
