### Upgrade notes

1. Install libmagic and development headers (`libmagic-dev` on Ubuntu/Debian, `file-dev` on Alpine Linux)
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

- 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

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>

</details>

- Fixed uploading webp images when the Exiftool Upload Filter is enabled by skipping them
- 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.

**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'
```
