Synapse 0.33.7 (2018-10-18)

Warning: This release removes the example email notification templates from res/templates (they are now internal to the python package). This should only affect you if you (a) deploy your Synapse instance from a git checkout or a github snapshot URL, and (b) have email notifications enabled.

If you have email notifications enabled, you should ensure that email.template_dir is either configured to point at a directory where you have installed customised templates, or leave it unset to use the default templates.
