	# Changelog

	All notable changes to this project will be documented in this file.

	The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).

	## Unreleased

	-## BREAKING
	+## Added
	+
	+## Fixed
	+
	+## Changed
	+- Dropped obsolete `ap_enabled` indicator from user table and associated buggy logic
	+- The remote user count in prometheus metrics is now an estimate instead of an exact number
	+ since the latter proved unreasonably costly to obtain for a merely nice-to-have statistic
	+- Various other tweaks improving stat query performance and avoiding unecessary work on received AP documents
	- The HTML content for new posts (both Client-to-Server as well as Server-to-Server communication) will now use a different formatting to represent MFM. See [FEP-c16b](https://codeberg.org/fediverse/fep/src/branch/main/fep/c16b/fep-c16b.md) for more details.

	## 2025.01.01

	Hotfix: Federation could break if a null value found its way into `should_federate?\1`

	## 2025.01

	## Added
	- New config option `:instance, :cleanup_attachments_delay`
	- It is now possible to display custom source URLs in akkoma-fe;
	the settings are part of the frontend configuration

	## Fixed
	- Media proxy no longer attempts to proxy embedded images
	- Fix significant uneccessary overhead of attachment cleanup;
	it no longer attempts to cleanup attachments of deleted remote posts
	- Fix “Delete & Redraft” often losing attachments if attachment cleanup was enabled
	- ObjectAge policy no longer lets unlisted posts slip through
	- ObjectAge policy no longer leaks belated DMs and follower-only posts
	- the NodeINfo endpoint now uses the correct content type

	## Changed
	- Anonymous objects now federate completely without an id
	adopting a proposed AP spec errata and restoring federation
	with e.g. IceShrimp.NET and fedify-based implementations

	## 3.13.3

	## BREAKING
	- Minimum PostgreSQL version is raised to 12
	- Swagger UI moved from `/akkoma/swaggerui/` to `/pleroma/swaggerui/`

	## Added
	- Implement [FEP-67ff](https://codeberg.org/fediverse/fep/src/branch/main/fep/67ff/fep-67ff.md) (federation documentation)
	- Meilisearch: it is now possible to use separate keys for search and admin actions
	- New standalone `prune_orphaned_activities` mix task with configurable batch limit
	- The `prune_objects` mix task now accepts a `--limit` parameter for initial object pruning

	## Fixed
	- Meilisearch: order of results returned from our REST API now actually matches how Meilisearch ranks results
	- Emoji are now federated as anonymous objects, fixing issues with
	some strict servers e.g. rejecting e.g. remote emoji reactions
	- AP objects with additional JSON-LD profiles beyond ActivityStreams can now be fetched
	- Single-selection polls no longer expose the voter_count; MastoAPI demands it be null
	and this confused some clients leading to vote distributions >100%

	## Changed
	- Refactored Rich Media to cache the content in the database. Fetching operations that could block status rendering have been eliminated.

	## 2024.04.1 (Security)

	## Fixed
	- Issue allowing non-owners to use media objects in posts
	- Issue allowing use of non-media objects as attachments and crashing timeline rendering
	- Issue allowing webfinger spoofing in certain situations

	## 2024.04

	## Added
	- Support for [FEP-fffd](https://codeberg.org/fediverse/fep/src/branch/main/fep/fffd/fep-fffd.md) (proxy objects)
	- Verified support for elixir 1.16
	- Uploadfilter `Pleroma.Upload.Filter.Exiftool.ReadDescription` returns description values to the FE so they can pre fill the image description field
	NOTE: this filter MUST be placed before `Exiftool.StripMetadata` to work

	## Changed
	- Inbound pipeline error handing was modified somewhat, which should lead to less incomprehensible log spam. Hopefully.
	- Uploadfilter `Pleroma.Upload.Filter.Exiftool` was replaced by `Pleroma.Upload.Filter.Exiftool.StripMetadata`;
	the latter strips all non-essential metadata by default but can be configured.
	To regain the old behaviour of only stripping GPS data set `purge: ["gps:all"]`.
	- Uploadfilter `Pleroma.Upload.Filter.Exiftool` has been renamed to `Pleroma.Upload.Filter.Exiftool.StripMetadata`
	- MRF.InlineQuotePolicy now prefers to insert display URLs instead of ActivityPub IDs
	- Old accounts are no longer listed in WebFinger as aliases; this was breaking spec

	## Fixed
	- Issue preventing fetching anything from IPv6-only instances
	- Issue allowing post content to leak via opengraph tags despite :estrict\_unauthenticated being set
	- Move activities no longer operate on stale user data
	- Missing definitions in our JSON-LD context
	- Issue mangling newlines in code blocks for RSS/Atom feeds
	- static\_fe squeezing non-square avatars and emoji
	- Issue leading to properly JSON-LD compacted emoji reactions being rejected
	- We now use a standard-compliant Accept header when fetching ActivityPub objects
	- /api/pleroma/notification\_settings was rejecting body parameters;
	this also broke changing this setting via akkoma-fe
	- Issue leading to Mastodon bot accounts being rejected
	- Scope misdetection of remote posts resulting from not recognising
	JSON-LD-compacted forms of public scope; affected e.g. federation with bovine
	- Ratelimits encountered when fetching objects are now respected; 429 responses will cause a backoff when we get one.

	## Removed
	- ActivityPub Client-To-Server write API endpoints have been disabled;
	read endpoints are planned to be removed next release unless a clear need is demonstrated

	## 2024.03

	## Added
	- CLI tasks best-effort checking for past abuse of the recent spoofing exploit
	- new `:mrf_steal_emoji, :download_unknown_size` option; defaults to `false`

	## Changed
	- `Pleroma.Upload, :base_url` now MUST be configured explicitly if used;
	use of the same domain as the instance is strongly discouraged
	- `:media_proxy, :base_url` now MUST be configured explicitly if used;
	use of the same domain as the instance is strongly discouraged
	- StealEmoji:
	- now uses the pack.json format;
	existing users must migrate with an out-of-band script (check release notes)
	- only steals shortcodes recognised as valid
	- URLs of stolen emoji is no longer predictable
	- The `Dedupe` upload filter is now always active;
	`AnonymizeFilenames` is again opt-in
	- received AP data is sanity checked before we attempt to parse it as a user
	- Uploads, emoji and media proxy now restrict Content-Type headers to a safe subset
	- Akkoma will no longer fetch and parse objects hosted on the same domain

	## Fixed
	- Critical security issue allowing Akkoma to be used as a vector for
	(depending on configuration) impersonation of other users or creation
	of bogus users and posts on the upload domain
	- Critical security issue letting Akkoma fall for the above impersonation
	payloads due to lack of strict id checking
	- Critical security issue allowing domains redirect to to pose as the initial domain
	(e.g. with media proxy's fallback redirects)
	- refetched objects can no longer attribute themselves to third-party actors
	(this had no externally visible effect since actor info is read from the Create activity)
	- our litepub JSON-LD schema is now served with the correct content type
	- remote APNG attachments are now recognised as images

	## Upgrade Notes

	- As mentioned in "Changed", `Pleroma.Upload, :base_url` MUST be configured. Uploads will fail without it.
	- Akkoma will refuse to start if this is not set.
	- Same with media proxy.

	## 2024.02

	## Added
	- Full compatibility with Erlang OTP26
	- handling of GET /api/v1/preferences
	- Akkoma API is now documented
	- ability to auto-approve follow requests from users you are already following
	- The SimplePolicy MRF can now strip user backgrounds from selected remote hosts

	## Changed
	- OTP builds are now built on erlang OTP26
	- The base Phoenix framework is now updated to 1.7
	- An `outbox` field has been added to actor profiles to comply with AP spec
	- User profile backgrounds do now federate with other Akkoma instances and Sharkey

	## Fixed
	- Documentation issue in which a non-existing nginx file was referenced
	- Issue where a bad inbox URL could break federation
	- Issue where hashtag rel values would be scrubbed
	- Issue where short domains listed in `transparency_obfuscate_domains` were not actually obfuscated

	## 2023.08

	## Added

	- Added a new configuration option to the MediaProxy feature that allows the blocking of specific domains from using the media proxy or being explicitly allowed by the Content-Security-Policy.
	- Please make sure instances you wanted to block media from are not in the MediaProxy `whitelist`, and instead use `blocklist`.
	- `OnlyMedia` Upload Filter to simplify restricting uploads to audio, image, and video types
	- ARM64 OTP builds
	- Ubuntu22 builds are available for develop and stable
	- other distributions are stable only
	- Support for Elixir 1.15
	- 1.14 is still supported
	- OTP26 is currently "unsupported". It will probably work, but due to the way
	it handles map ordering, the test suite will not pass for it as yet.

	## Changed

	- Alpine OTP builds are now from alpine 3.18, which is OpenSSLv3 compatible.
	If you use alpine OTP builds you will have to update your local system.
	- Debian OTP builds are now from a base of bookworm, which is OpenSSLv3 compatible.
	If you use debian OTP builds you will have to update your local system to
	bookworm (currently: stable).
	- Ubuntu and debian builds are compatible again! (for now...)
	- Blocks/Mutes now return from max ID to min ID, in line with mastodon.
	- The AnonymizeFilename filter is now enabled by default.

	## Fixed

	- Deactivated users can no longer show up in the emoji reaction list
	- Embedded posts can no longer bypass `:restrict\_unauthenticated`
	- GET/HEAD requests will now work when requesting AWS-based instances.

	## Security

	- Add `no_new_privs` hardening to OpenRC and systemd service files
	- XML parsers cannot load any entities (thanks @Mae@is.badat.dev!)
	- Reduced permissions of config files and directories, distros requiring greater permissions like group-read need to pre-create the directories

	## Removed

	- Builds for debian oldstable (bullseye)
	- If you are on oldstable you should NOT attempt to update OTP builds without
	first updating your machine.

	## 2023.05

	## Added
	- Custom options for users to accept/reject private messages
	- options: everybody, nobody, people\_i\_follow
	- MRF to reject notes from accounts newer than a given age
	- this will have the side-effect of rejecting legitimate messages if your
	post gets boosted outside of your local bubble and people your instance
	does not know about reply to it.

	## Fixed
	- Support for `streams` public key URIs
	- Bookmarks are cleaned up on DB prune now

	## Security
	- Fixed mediaproxy being a bit of a silly billy

	## 2023.04

	## Added
	- Nodeinfo keys for unauthenticated timeline visibility
	- Option to disable federated timeline
	- Option to make the bubble timeline publicly accessible
	- Ability to swap between installed standard frontends
	- mastodon frontends are still not counted as standard frontends due to the complexity in serving them correctly.

	### Upgrade Notes
	- Elixir 1.14 is now required. If your distribution does not package this, you can
	use [asdf](https://asdf-vm.com/). At time of writing, elixir 1.14.3 / erlang 25.3
	is confirmed to work.

	## 2023.03

	## Fixed
	- Allowed contentMap to be updated on edit
	- Filter creation now accepts expires\_at

	### Changed
	- Restoring the database from a dump now goes much faster without need for work-arounds
	- Misskey reaction matching uses `content` parameter now

	### Added
	- Extend the mix task `prune_objects` with option `--prune-orphaned-activities` to also prune orphaned activities, allowing to reclaim even more database space

	### Removed
	- Possibility of using the `style` parameter on `span` elements. This will break certain MFM parameters.
	- Option for "default" image description.

	## 2023.02

	### Added
	- Prometheus metrics exporting from `/api/v1/akkoma/metrics`
	- Ability to alter http pool size

	- Ability to set posting language in the post form, API parity with mastodon
	- Ability to match domains in MRF by a trailing wildcard
	- Currently supported formats:
	- `example.com` (implicitly matches `*.example.com`)
	- `*.example.com`
	- `example.` (implicitly matches `.example.*`)

	### Removed
	- Non-finch HTTP adapters
	- Legacy redirect from /api/pleroma/admin to /api/v1/pleroma/admin
	- Legacy redirects from /api/pleroma to /api/v1/pleroma
	- :crypt dependency

	### Changed
	- Return HTTP error 413 when uploading an avatar or banner that's above the configured upload limit instead of a 500.
	- Non-admin users now cannot register `admin` scope tokens (not security-critical, they didn't work before, but you _could_ create them)
	- Admin scopes will be dropped on create
	- Rich media will now backoff for 20 minutes after a failure
	- Quote posts are now considered as part of the same thread as the post they are quoting
	- Extend the mix task `prune_objects` with options to keep more relevant posts
	- Simplified HTTP signature processing
	- Rich media will now hard-exit after 5 seconds, to prevent timeline hangs
	- HTTP Content Security Policy is now far more strict to prevent any potential XSS/CSS leakages
	- Follow requests are now paginated, matches mastodon API spec, so use the Link header to paginate.

	### Fixed
	- /api/v1/accounts/lookup will now respect restrict\_unauthenticated
	- Unknown atoms in the config DB will no longer crash akkoma on boot

	### Upgrade notes
	- Ensure `config :tesla, :adapter` is either unset, or set to `{Tesla.Adapter.Finch, name: MyFinch}` in your .exs config
	- Pleroma-FE will need to be updated to handle the new /api/v1/pleroma endpoints for custom emoji

	## 2022.12

	## Added
	- Config: HTTP timeout options, :pool\_timeout and :receive\_timeout
	- Added statistic gathering about instances which do/don't have signed fetches when they request from us
	- Ability to set a default post expiry time, after which the post will be deleted. If used in concert with ActivityExpiration MRF, the expiry which comes _sooner_ will be applied.
	- Regular task to prune local transient activities
	- Task to manually run the transient prune job (pleroma.database prune\_task)
	- Ability to follow hashtags
	- Option to extend `reject` in MRF-Simple to apply to entire threads, where the originating instance is rejected
	- Extra information to failed HTTP requests

	## Changed
	- MastoAPI: Accept BooleanLike input on `/api/v1/accounts/:id/follow` (fixes follows with mastodon.py)
	- Relays from akkoma are now off by default
	- NormalizeMarkup MRF is now on by default
	- Follow/Block/Mute imports now spin off into n tasks to avoid the oban timeout
	- Transient activities recieved from remote servers are no longer persisted in the database

	## Removed
	- FollowBotPolicy
	- Passing of undo/block into MRF

	## Upgrade Notes
	- If you have an old instance, you will probably want to run `mix pleroma.database prune_task` in the foreground to catch it up with the history of your instance.

	## 2022.11

	## Added
	- Officially supported docker release
	- Ability to remove followers unilaterally without a block
	- Scraping of nodeinfo from remote instances to display instance info
	- `requested_by` in relationships when the user has requested to follow you

	## Changed

	## Fixed
	- Registrations via ldap are now compatible with the latest OTP24

	## Update notes
	- If you use LDAP and run from source, please update your elixir/erlang
	to the latest. The changes in OTP24.3 are breaking.

	### Changed
	- Allow users to remove their emails if instance does not need email to register

	### Added
	- `activeMonth` and `activeHalfyear` fields in NodeInfo usage.users object
	- Experimental support for Finch. Put `config :tesla, :adapter, {Tesla.Adapter.Finch, name: MyFinch}` in your secrets file to use it. Reverse Proxy will still use Hackney.

	### Changed

	- Breaking: Configuration: `:chat, enabled` moved to `:shout, enabled` and `:instance, chat_limit` moved to `:shout, limit`
	- Breaking Entries for simple_policy, transparency_exclusions and quarantined_instances now list both the instance and a reason.
	- Support for Erlang/OTP 24
	- The `application` metadata returned with statuses is no longer hardcoded. Apps that want to display these details will now have valid data for new posts after this change.
	- HTTPSecurityPlug now sends a response header to opt out of Google's FLoC (Federated Learning of Cohorts) targeted advertising.
	- Email address is now returned if requesting user is the owner of the user account so it can be exposed in client and FE user settings UIs.
	- Improved Twittercard and OpenGraph meta tag generation including thumbnails and image dimension metadata when available.
	- AdminAPI: sort users so the newest are at the top.
	- ActivityPub Client-to-Server(C2S): Limitation on the type of Activity/Object are lifted as they are now passed through ObjectValidators
	- MRF (`AntiFollowbotPolicy`): Bot accounts are now also considered followbots. Users can still allow bots to follow them by first following the bot.

	### Added

	- MRF (`FollowBotPolicy`): New MRF Policy which makes a designated local Bot account attempt to follow all users in public Notes received by your instance. Users who require approving follower requests or have #nobot in their profile are excluded.
	- Return OAuth token `id` (primary key) in POST `/oauth/token`.
	- AdminAPI: return `created_at` date with users.
	- AdminAPI: add DELETE `/api/v1/pleroma/admin/instances/:instance` to delete all content from a remote instance.
	- `AnalyzeMetadata` upload filter for extracting image/video attachment dimensions and generating blurhashes for images. Blurhashes for videos are not generated at this time.
	- Attachment dimensions and blurhashes are federated when available.
	- Mastodon API: support `poll` notification.
	- Pinned posts federation
	- Possibility to discover users like `user@example.org`, while Akkoma is working on `akkoma.example.org`. Additional configuration required.

	### Fixed
	- Don't crash so hard when email settings are invalid.
	- Checking activated Upload Filters for required commands.
	- Remote users can no longer reappear after being deleted.
	- Deactivated users may now be deleted.
	- Deleting an activity with a lot of likes/boosts no longer causes a database timeout.
	- Mix task `pleroma.database prune_objects`
	- Fixed rendering of JSON errors on ActivityPub endpoints.
	- Linkify: Parsing crash with URLs ending in unbalanced closed paren, no path separator, and no query parameters
	- Try to save exported ConfigDB settings (migrate_from_db) in the system temp directory if default location is not writable.
	- Uploading custom instance thumbnail via AdminAPI/AdminFE generated invalid URL to the image
	- Applying ConcurrentLimiter settings via AdminAPI
	- User login failures if their `notification_settings` were in a NULL state.

	## [2.1.2] - 2020-09-17

	### Security

	- Fix most MRF rules either crashing or not being applied to objects passed into the Common Pipeline (ChatMessage, Question, Answer, Audio, Event).

	### Fixed

	- Welcome Chat messages preventing user registration with MRF Simple Policy applied to the local instance.

	- Mastodon Streaming API: Handler crashes on authentication failures, resulting in error logs.
	- Mastodon Streaming API: Error logs on client pings.
	- Rich media: Log spam on failures. Now the error is only logged once per attempt.

	### Changed

	- Rich Media: A HEAD request is now done to the url, to ensure it has the appropriate content type and size before proceeding with a GET.

	### Upgrade notes

	- Fix possible DoS in Admin API search using an atom leak vulnerability. Authentication with admin rights was required to exploit.

	### Changed

	- Improved error message when cmake is not available at build stage.

	### Added
	- Rich media failure tracking (along with `:failure_backoff` option).

	- Password resets no longer processed for deactivated accounts.
	- Favicon scraper raising exceptions on URLs longer than 255 characters.

	## [2.1.0] - 2020-08-28

	### Changed

	- Breaking: The default descriptions on uploads are now empty. The old behavior (filename as default) can be configured, see the cheat sheet.
	- Breaking: Added the ObjectAgePolicy to the default set of MRFs. This will delist and strip the follower collection of any message received that is older than 7 days. This will stop users from seeing very old messages in the timelines. The messages can still be viewed on the user's page and in conversations. They also still trigger notifications.
	- Breaking: Elixir >=1.9 is now required (was >= 1.8)
	- Breaking: Configuration: `:auto_linker, :opts` moved to `:pleroma, Pleroma.Formatter`. Old config namespace is deprecated.
	- Breaking: Configuration: `:instance, welcome_user_nickname` moved to `:welcome, :direct_message, :sender_nickname`, `:instance, :welcome_message` moved to `:welcome, :direct_message, :message`. Old config namespace is deprecated.
	- Breaking: LDAP: Fallback to local database authentication has been removed for security reasons and lack of a mechanism to ensure the passwords are synchronized when LDAP passwords are updated.
	- Breaking Changed defaults for `:restrict_unauthenticated` so that when `:instance, :public` is set to `false` then all `:restrict_unauthenticated` items be effectively set to `true`. If you'd like to allow unauthenticated access to specific API endpoints on a private instance, please explicitly set `:restrict_unauthenticated` to non-default value in `config/prod.secret.exs`.
	- In Conversations, return only direct messages as `last_status`
	- Using the `only_media` filter on timelines will now exclude reblog media
	- MFR policy to set global expiration for all local Create activities
	- OGP rich media parser merged with TwitterCard
	- Configuration: `:instance, rewrite_policy` moved to `:mrf, policies`, `:instance, :mrf_transparency` moved to `:mrf, :transparency`, `:instance, :mrf_transparency_exclusions` moved to `:mrf, :transparency_exclusions`. Old config namespace is deprecated.
	- Configuration: `:media_proxy, whitelist` format changed to host with scheme (e.g. `http://example.com` instead of `example.com`). Domain format is deprecated.

	- Breaking: AdminAPI: migrate_from_db endpoint
	</details>

	### Changed
	- Breaking: Pleroma won't start if it detects unapplied migrations
	- Breaking: Elixir >=1.8 is now required (was >= 1.7)
	- Breaking: `Pleroma.Plugs.RemoteIp` and `:rate_limiter` enabled by default. Please ensure your reverse proxy forwards the real IP!
	- 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
	- Add `rel="ugc"` to all links in statuses, to prevent SEO spam
	- Extract RSS functionality from OStatus
	- MRF (Simple Policy): Also use `:accept`/`:reject` on the actors rather than only their activities
	- OStatus: Extract RSS functionality
	- Deprecated `User.Info` embedded schema (fields moved to `User`)
	- Store status data inside Flag activity
	- Deprecated (reorganized as `UserRelationship` entity) User fields with user AP IDs (`blocks`, `mutes`, `muted_reblogs`, `muted_notifications`, `subscribers`).
	- 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.
	- Allow account registration without an email
	- Default to `prepare: :unnamed` in the database configuration.
	- Instance stats are now loaded on startup instead of being empty until next hourly job.

	## ActivityPub

	Akkoma mostly follows the server-to-server parts of the ActivityPub standard,
	but implements quirks for Mastodon compatibility as well as Mastodon-specific
	and custom extensions.

	See our documentation and Mastodon’s federation information
	linked further below for details on these quirks and extensions.

	Akkoma does not perform JSON-LD processing.

	### Required extensions

	#### HTTP Signatures
	All AP S2S POST requests to Akkoma instances MUST be signed.
	Depending on instance configuration the same may be true for GET requests.

	### FEP-c16b: Formatting MFM functions

	The optional extension term `htmlMfm` is currently not used.

	## Nodeinfo

	Akkoma provides many additional entries in its nodeinfo response,
	see the documentation linked below for details.
