    926da4dd · 0.33.7 ·
    **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.
    
    The configuration parser will try to detect the situation where
    `email.template_dir` is incorrectly set to `res/templates` and do the right
    thing, but will warn about this.
