It's release o'clock - GDPR time!!!!
v0.30.0 sees the introduction of Server Notices, which provides a channel whereby server administrators can send messages to users on the server, as well as Consent Management for tracking whether users have agreed to the terms and conditions set by the administrator of a server - and blocking access to the server until they have.
In conjunction these features support GDPR compliance in the form of providing a client agnostic means to contact users and ask for consent/agreement to a Privacy Notice.
For more information about our approach to GDPR compliance take a look here (although be aware that our position has evolved a bit; see the upcoming new privacy policy for the Matrix.org homeserver for details).
Additionally there are a host of bug fixes and refactors as well as an enhancement to our Dockerfile.

They are used as part of communication of the server policies (see Consent Tracking), however the intention is that they may also find a use for features such as "Message of the day".
This feature is specific to Synapse, but uses standard Matrix communication mechanisms,
so should work with any Matrix client. For more details see here.
