-
- Test editing saved messages.
- Remove ThreadPoolExecutor from test_wait_next_messages.
- Move test_two_group_securejoins from receive_imf to securejoin module.
- At the end of securejoin Bob has two members in a group chat.
- Bob has 0 members in the chat until securejoin finishes.
- Do not add QR inviter to groups right after scanning the code.
-
-## [2.25.0] - 2025-11-05
-
-### Features / Changes
-
- Put self-name into group invite codes ([#7398](https://github.com/chatmail/core/pull/7398)).
- Slightly nicer and shorter QR and invite codes ([#7390](https://github.com/chatmail/core/pull/7390))
-
-### Fixes
-
- Add device message instead of partial message when receive_imf fails. This fixes a rare bug where the IMAP loop got stuck.
- Add info message if user tries to create a QR code for deprecated channel ([#7399](https://github.com/chatmail/core/pull/7399)).
-
-### Miscellaneous Tasks
-
