Synapse v0.99.x is a precursor to the upcoming Synapse v1.0 release. It contains foundational changes to room architecture and the federation security model necessary to support the upcoming r0 release of the Server to Server API.

Features

  • Synapse's cipher string has been updated to require ECDH key exchange. Configuring and generating dh_params is no longer required, and they will be ignored. (#4229)
  • Synapse can now automatically provision TLS certificates via ACME (the protocol used by CAs like Let's Encrypt). (#4384, #4492, #4525, #4572, #4564, #4566, #4547, #4557)
  • Implement MSC1708 (.well-known routing for server-server federation) (#4408, #4409, #4426, #4427, #4428, #4464, #4468, #4487, #4488, #4489, #4497, #4511, #4516, #4520, #4521, #4539, #4542, #4544)
  • Search now includes results from predecessor rooms after a room upgrade. (#4415)
  • Config option to disable requesting MSISDN on registration. (#4423)
  • Add a metric for tracking event stream position of the user directory. (#4445)
  • Support exposing server capabilities in CS API (MSC1753, MSC1804) (#4472, 81b7e7eed))
  • Add support for room version 3 (#4483, #4499, #4515, #4523, #4535)
  • Synapse will now reload TLS certificates from disk upon SIGHUP. (#4495, #4524)
  • The matrixdotorg/synapse Docker images now use Python 3 by default. (#4558)
