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.
