  - Some e-mail spam filters penalize e-mails that have a `Message-ID` header that uses a different domain name than the sending e-mail address. Now, the same domain will be used

  for sign-up
- Add `policy` param to `POST /api/v1/push/subscriptions` in REST API ([Gargron](https://github.com/mastodon/mastodon/pull/16040))

  - 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)
