  - Previously, getting live updates for multiple timelines required opening a HTTP or WebSocket connection for each
  - More connections means more resource consumption on both ends, not to mention the (ever so slight) delay when establishing a new connection
  - Now, with just a single WebSocket connection you can subscribe and unsubscribe to and from multiple streams
- Add support for limiting results by both `min_id` and `max_id` at the same time in REST API ([tateisu](https://github.com/mastodon/mastodon/pull/14776))

- **Fix deletes not reaching every server that interacted with toot** ([Gargron](https://github.com/mastodon/mastodon/pull/15200))
  - Previously, delete of a toot would be primarily sent to the followers of its author, people mentioned in the toot, and people who reblogged the toot
  - Now, additionally, it is ensured that it is sent to people who replied to it, favourited it, and to the person it replies to even if that person is not mentioned

  - Some time ago, browsers added a requirement that desktop notification prompts could only be displayed in response to a user-generated event (such as a click)
  - This means that for some time, users who haven't already given the permission before were not getting a prompt and as such were not receiving desktop notifications
