- **Breaking:** Configuration: A setting to explicitly disable the mailer was added, defaulting to true, if you are using a mailer add `config :pleroma, Pleroma.Emails.Mailer, enabled: true` to your config
- Configuration: OpenGraph and TwitterCard providers enabled by default
- Configuration: Filter.AnonymizeFilename added ability to retain file extension with custom text
- Federation: Return 403 errors when trying to request pages from a user's follower/following collections if they have `hide_followers`/`hide_follows` set
- NodeInfo: Return `skipThreadContainment` in `metadata` for the `skip_thread_containment` option
### Fixed
