v0.20.0

• Bumped minimum Go version to 1.22.
• (bridgev2) Added more features and fixed bugs.
• (event) Added types for MSC4144: Per-message profiles.
• (federation) Added implementation of server name resolution and a basic client for making federation requests.
• (crypto/ssss) Changed recovery key/passphrase verify functions to take the key ID as a parameter to ensure it's correctly set even if the key metadata wasn't fetched via GetKeyData.
• (format/mdext) Added goldmark extensions for single-character bold, italic and strikethrough parsing (as in *foo* -> foo, _foo_ -> foo and ~foo~ -> foo)
• (format) Changed RenderMarkdown et al to always include m.mentions in returned content. The mention list is filled with matrix.to URLs from the input by default.

v0.19.0

Also note the v0.19.0-beta.1 changelog, there were some slightly breaking changes.

• Renamed master branch to main.
• (bridgev2) Added more features.
• (crypto) Fixed bug with copying m.relates_to from wire content to decrypted content.
• (mediaproxy) Added module for implementing simple media repos that proxy requests elsewhere.
• (client) Changed Members() to automatically parse event content for all returned events.
• (bridge) Added /register call if /versions fails with M_FORBIDDEN.
• (crypto) Fixed DecryptMegolmEvent sometimes calling database without transaction by using the non-context version of ResolveTrust.
• (crypto/attachment) Implemented io.Seeker in EncryptStream to allow using it in retriable HTTP requests.
• (event) Added helper method to add user ID to a Mentions object.
• (event) Fixed default power level for invites (thanks to @​rudis in #250).
• (client) Fixed incorrect warning log in State() when state store returns no error (thanks to @​rudis in #249).
• (crypto/verificationhelper) Fixed deadlock when ignoring unknown cancellation events (thanks to @​rudis in #247).

v0.19.0-beta.1

• (bridgev2) Added experimental high-level bridge framework.
• (hicli) Added experimental high-level client framework.
• Slightly breaking changes
  • (crypto) Added room ID and first known index parameters to SessionReceived callback.
  • (crypto) Changed ImportRoomKeyFromBackup to return the imported session.
  • (client) Added error parameter to ResponseHook.
  • (client) Changed Download to return entire response instead of just an io.Reader.
• (crypto) Changed initial olm device sharing to save keys before sharing to ensure keys aren't accidentally regenerated in case the request fails.
• (crypto) Changed EncryptMegolmEvent and ShareGroupSession to return more errors instead of only logging and ignoring them.
• (crypto) Added option to completely disable megolm ratchet tracking.
  • The tracking is meant for bots and bridges which may want to delete old keys, but for normal clients it's just unnecessary overhead.
• (crypto) Changed Megolm session storage methods in Store to not take sender key as parameter.
  • This causes a breaking change to the layout of the MemoryStore struct. Using MemoryStore in production is not recommended.
• (crypto) Changed DecryptMegolmEvent to copy m.relates_to in the raw content too instead of only in the parsed struct.
• (crypto) Exported function to parse megolm message index from raw ciphertext bytes.
• (crypto/sqlstore) Fixed schema of crypto_secrets table to include account ID.
• (crypto/verificationhelper) Fixed more bugs.
• (client) Added UpdateRequestOnRetry hook which is called immediately before retrying a normal HTTP request.
• (client) Added support for MSC3916 media download endpoint.
  • Support is automatically detected from spec versions. The SpecVersions property can either be filled manually, or Versions can be called to automatically populate the field with the response.
• (event) Added constants for known room versions.
