Synapse 1.110.0rc1 (2024-06-26)

Features

• Add initial implementation of an experimental MSC3575 Sliding Sync /sync endpoint. (#17187, #17301)
  • Native sliding sync support is coming, but is not yet ready for usage outside of initial client development and testing. Expect to see much more on this feature in the next few Synapse releases.
• Add experimental support for MSC3823 - Account suspension. (#17255)
• Improve ratelimiting in Synapse. (#17256)
• Add support for the unstable MSC4151 report room API. (#17270, #17296)
• Filter for public and empty rooms added to Admin-API List Room API. (#17276)

• register_new_matrix_user now supports a --password-file flag, which
  is useful for scripting. (#17294)

  This is useful for scripts that bootstrap user accounts with initial passwords. (#17304)
• Add support for via query parameter from MSC4156. (#17322)
• Add is_invite filtering to experimental MSC3575 Sliding Sync /sync endpoint. (#17335)

• Add debug logging for when room keys are uploaded, including whether they are replacing other room keys. (#17266)
• Handle OTK uploads off master. (#17271)
• Don't try and resync devices for remote users whose servers are marked as down. (#17273)
• Re-organize Pydantic models and types used in handlers. (#17279)
• Expose the worker instance that persisted the event on event.internal_metadata.instance_name. (#17300)
• Update the README with Element branding, improve headers and fix the #synapse:matrix.org support room link rendering. (#17324)
• Change path of the experimental MSC3575 Sliding Sync implementation to /org.matrix.simplified_msc3575/sync since our simplified API is slightly incompatible with what's in the current MSC. (#17331)
