- Followers-only conversations. Previously, the default visibility of a reply to a followers-only post was "Direct". In this release the default was changed to "Conversation", which preserves the audience of a top-level post. Followers-only replies with correct audience (such as those published by servers that implement Conversation Containers) will also have "Conversation" visibility.
- New filter actions: reject-profile-images and reject-custom-emojis. The reject-media action was renamed to reject-media-attachments.
