The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
## [Unreleased]
+### Security
+- Mastodon API: Fix being able to request enourmous amount of statuses in timelines leading to DoS. Now limited to 40 per request.
+
### Removed
- **Breaking**: Removed 1.0+ deprecated configurations `Pleroma.Upload, :strip_exif` and `:instance, :dedupe_media`
- **Breaking**: OStatus protocol support
- **Breaking:** attachment links (`config :pleroma, :instance, no_attachment_links` and `config :pleroma, Pleroma.Upload, link_name`) disabled by default
- **Breaking:** OAuth: defaulted `[:auth, :enforce_oauth_admin_scope_usage]` setting to `true` which demands `admin` OAuth scope to perform admin actions (in addition to `is_admin` flag on User); make sure to use bundled or newer versions of AdminFE & PleromaFE to access admin / moderator features.
- **Breaking:** Dynamic configuration has been rearchitected. The `:pleroma, :instance, dynamic_configuration` setting has been replaced with `config :pleroma, configurable_from_database`. Please backup your configuration to a file and run the migration task to ensure consistency with the new schema.
+- **Breaking:** `:instance, no_attachment_links` has been replaced with `:instance, attachment_links` which still takes a boolean value but doesn't use double negative language.
- Replaced [pleroma_job_queue](https://git.pleroma.social/pleroma/pleroma_job_queue) and `Pleroma.Web.Federator.RetryQueue` with [Oban](https://github.com/sorentwo/oban) (see [`docs/config.md`](docs/config.md) on migrating customized worker / retry settings)
- Introduced [quantum](https://github.com/quantum-elixir/quantum-core) job scheduler
- Enabled `:instance, extended_nickname_format` in the default config
- Rate limiter is now disabled for localhost/socket (unless remoteip plug is enabled)
- Logger: default log level changed from `warn` to `info`.
- Config mix task `migrate_to_db` truncates `config` table before migrating the config file.
+- Default to `prepare: :unnamed` in the database configuration.
+- Instance stats are now loaded on startup instead of being empty until next hourly job.
