akkoma/CHANGELOG.md

# 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

## 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

## Changed
- Inbound pipeline error handing was modified somewhat, which should lead to less incomprehensible log spam. Hopefully.
- Uploadfilter `Pleroma.Upload.Filter.Exiftool` has been renamed to `Pleroma.Upload.Filter.Exiftool.StripMetadata`

## Fixed
- Issue preventing fetching anything from IPv6-only instances
- Issue allowing post content to leak via opengraph tags despite :estrict\_unauthenticated being set

## 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
- 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

- 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

## [2.2.0] - 2020-11-12

### Security

- Fixed the possibility of using file uploads to spoof posts.

### Changed

- **Breaking** Requires `libmagic` (or `file`) to guess file types.
- **Breaking:** App metrics endpoint (`/api/pleroma/app_metrics`) is disabled by default, check `docs/API/prometheus.md` on enabling and configuring.
- **Breaking:** Pleroma Admin API: emoji packs and files routes changed.
- **Breaking:** Sensitive/NSFW statuses no longer disable link previews.
- Search: Users are now findable by their urls.
- Renamed `:await_up_timeout` in `:connections_pool` namespace to `:connect_timeout`, old name is deprecated.

switched to a new configuration mechanism, however it was not officially removed until now.

### Added

- Media preview proxy (requires `ffmpeg` and `ImageMagick` to be installed and media proxy to be enabled; see `:media_preview_proxy` config for more details).

2. Run database migrations (inside Pleroma directory):
  - OTP: `./bin/pleroma_ctl migrate`
  - From Source: `mix ecto.migrate`
3. Restart Pleroma

## [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 API: the public timeline returning an error when the `reply_visibility` parameter is set to `self` for an unauthenticated user.
- 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

### Upgrade notes

1. Restart Pleroma

## [2.1.1] - 2020-09-08

### Security
- Fix possible DoS in Mastodon API user search due to an error in match clauses, leading to an infinite recursion and subsequent OOM with certain inputs.
- Fix metadata leak for accounts and statuses on private instances.
- Fix possible DoS in Admin API search using an atom leak vulnerability. Authentication with admin rights was required to exploit.

### Changed

- **Breaking:** The metadata providers RelMe and Feed are no longer configurable. RelMe should always be activated and Feed only provides a <link> header tag for the actual RSS/Atom feed when the instance is public.
- Improved error message when cmake is not available at build stage.

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

<details>

- Mastodon API: Search parameter `following` now correctly returns the followings rather than the followers
- Mastodon API: Timelines hanging for (`number of posts with links * rich media timeout`) in the worst case.
  Reduced to just rich media timeout.
- Mastodon API: Cards being wrong for preview statuses due to cache key collision.
- 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.

delete from users where ap_id = 'https://your.instance.hostname/relay';
```

**OTP Note:** `pleroma_ctl` in 1.0 defaults to `master` and doesn't support specifying arbitrary branches, making `./pleroma_ctl update` fail. To fix this, fetch a version of `pleroma_ctl` from 1.1 using the command below and proceed with the update normally:
```
curl -Lo ./bin/pleroma_ctl 'https://git.pleroma.social/pleroma/pleroma/raw/develop/rel/files/bin/pleroma_ctl'
