@ -8,6 +8,7 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
### Changed
- **Breaking:** Changed storage of hashtags in plain-text to `object->hashtags`, run [`pleroma.database fill_old_hashtags` mix task](docs/administration/CLI_tasks/database.md) for old objects (works while pleroma is running).
- Polls now always return a `voters_count`, even if they are single-choice.
- Admin Emails: The ap id is used as the user link in emails now.
- Improved registration workflow for email confirmation and account approval modes.
@ -443,7 +444,6 @@ switched to a new configuration mechanism, however it was not officially removed
- Static-FE: Fix remote posts not being sanitized
### Fixed
=======
- Rate limiter crashes when there is no explicitly specified ip in the config
- 500 errors when no `Accept` header is present if Static-FE is enabled
- Instance panel not being updated immediately due to wrong `Cache-Control` headers
