   Group notifications of the same type for the same target, so that your notifications no longer get cluttered by boost and favorite notifications as soon as a couple of your posts get traction.\
   This is done server-side so that clients can efficiently get relevant groups without having to go through numerous pages of individual notifications.\
   As part of this, the visual design of the entire notifications feature has been revamped.\
   This feature is intended to eventually replace the existing notifications column, but for this first beta, users will have to enable it in the “Experimental features” section of the notifications column settings.\
   The API is not final yet, but it consists of:
   - a new `group_key` attribute to `Notification` entities

   The old “Block notifications from non-followers”, “Block notifications from people you don't follow” and “Block direct messages from people you don't follow” notification settings have been replaced by a new set of settings found directly in the notification column.\
   You can now separately filter or drop notifications from people you don't follow, people who don't follow you, accounts created within the past 30 days, as well as unsolicited private mentions, and accounts limited by the moderation.\
   Instead of being outright dropped, notifications that you chose to filter are put in a separate “Filtered notifications” box that you can review separately without it clogging your main notifications.\

 - **Change follow recommendations algorithm** (#28314, #28433, #29017, #29108, #29306, #29550, #29619, and #31474 by @ClearlyClaire, @Gargron, @kernal053, @mjankowski, and @wheatear-dev)\
   This replaces the “past interactions” recommendation algorithm with a “friends of friends” algorithm that suggests accounts followed by people you follow, and a “similar profiles” algorithm that suggests accounts with a profile similar to your most recent follows.\
   In addition, the implementation has been significantly reworked, and all follow recommendations are now dismissable.\
   This change deprecates the `source` attribute in `Suggestion` entities in the REST API, and replaces it with the new [`sources` attribute](https://docs.joinmastodon.org/entities/Suggestion/#sources).

   In order to reduce the amount of runtime dependencies, the streaming server has been moved into a separate package and Docker image.\
   The `mastodon` image does not contain the streaming server anymore, as it has been moved to its own `mastodon-streaming` image.\
   Administrators may need to update their setup accordingly.
