• Bumped minimum Go version to 1.18.
• Added hidden option to use appservice login for double puppeting.
  • This can be used by adding everyone to a non-exclusive namespace in the registration, and setting the login shared secret to the string appservice.
• 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.
• Updated sticker bridging to send actual sticker messages to WhatsApp rather than sending as image. This includes converting stickers to webp and adding transparent padding to make the aspect ratio 1:1.
• Added automatic webm -> mp4 conversion when sending videos to WhatsApp.
• Started rejecting unsupported mime types when sending media to WhatsApp.
• Added option to use MSC2409 and MSC3202 for end-to-bridge encryption. However, this may not work with the Synapse implementation as it hasn't been tested yet.
• Added error notice if the bridge is started twice.
