v0.4.0

• Added support for bridging room mentions in both directions.
• Updated formatter to insert Matrix displayname into mentions when bridging from Google Chat. This ensures that the Matrix user gets mentioned correctly.
• Fixed images from Google Chat not being bridged with full resolution.
• Added SQLite support (thanks to @durin42 in #74).
• Updated Docker image to Alpine 3.16.
• Enabled appservice ephemeral events by default for new installations.
  • Existing bridges can turn it on by enabling ephemeral_events and disabling sync_with_custom_puppets in the config, then regenerating the registration file.
• Added options to make encryption more secure.
  • The encryption -> verification_levels config options can be used to make the bridge require encrypted messages to come from cross-signed devices, with trust-on-first-use validation of the cross-signing master key.
  • The encryption -> require option can be used to make the bridge ignore any unencrypted messages.
  • Key rotation settings can be configured with the encryption -> rotation config.
