 ### Changed
 - **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
 - **Breaking:** Configuration: `/media/` is now removed when `base_url` is configured, append `/media/` to your `base_url` config to keep the old behaviour if desired
+- **Breaking:** `/api/pleroma/notifications/read` is moved to `/api/v1/pleroma/notifications/read` and now supports `max_id` and responds with Mastodon API entities.
 - 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
