# [unreleased]

# 0.20.3

Bug fixes:

- Fix `Capabilities::get()` and `Capabilities::set()`. They were not up-to-date
  to handle the `m.get_login_token` capability.

Improvements:

- Remove the unstable support for MSC3575 as it was closed. MSC4186 should be
  used instead.
- The `authentication` field of `discovery::discover_homeserver::Response` has
  been removed in favour of `discovery::get_authorization_server_metadata`.
- The `discovery::discover_homeserver::Response` well-known now includes the
  `rtc_foci` as defined in MSC4143.
- Use specialized room ID type (`ExtensionRoomConfig`) for all MSC4186
  extension requests, not just the Receipts extension.

# 0.20.2

Improvements:

- Add support for the authorization server metadata endpoint, according to the
  latest draft of MSC2965.
- Add the `guest_access_token` field to `account::register::v3::Request` to
  allow a guest user to upgrade to a regular account.
- Add the endpoints for peeking: `get_current_state` and `listen_to_new_events`.
- Add the `reporting::report_user` endpoint to report users, according to Matrix
  1.14.

# 0.20.1

Bug fixes:

- `unstable-msc4186` without `unstable-msc3575` no longer create a compilation
  failure.

Improvements:

- Add support for new dehydration format, according to the latest draft of
  MSC3814.
- Add unstable support for OIDC-aware compatibility, according to MSC3824.
- Stabilize support for reporting rooms, according to Matrix 1.13.
  - Removes the `unstable-msc4151` cargo feature.

# 0.20.0

Breaking changes:

- `ErrorKind` does not implement `AsRef<str>` and `Display` anymore. To get the
  same result, use `ErrorKind::errcode()`. The `ErrorCode` that is returned
  implements those traits.

Bug fixes:

- `knock_state` in `KnockedRoom` and `events` in `KnockState` are no longer
  required during deserialization and are no longer serialized if they are empty.
  This was a deviation from the spec, those fields were never required.

Improvements:

- Add unstable support for reporting rooms, according to MSC4151.
- The `unstable-exhaustive-types` cargo feature was replaced by the
  `ruma_unstable_exhaustive_types` compile-time `cfg` setting. Like all `cfg`
  settings, it can be enabled at compile-time with the `RUSTFLAGS` environment
  variable, or inside `.cargo/config.toml`. It can also be enabled by setting
  the `RUMA_UNSTABLE_EXHAUSTIVE_TYPES` environment variable.
- Add `ErrorKind::ThreepidMediumNotSupported`, according to MSC4178.
- Add `ErrorKind::UserSuspended`, according to MSC3823.
- `EmailPusherData` allows to set custom data for the pusher in the `data` field, due
  to a clarification in the spec.

  as before.
- Change type of `client_secret` field in `ThirdpartyIdCredentials`
  from `Box<ClientSecret>` to `OwnedClientSecret`

  `media::get_content_as_filename::v3::Response` use now the strongly typed
  `ContentDisposition` instead of strings.
- Replace `server_name` on `knock::knock_room::v3::Request` and 
  `membership::join_room_by_id_or_alias::v3::Request` with `via` as per MSC4156
  / Matrix 1.12.
- Remove `RuleScope`, due to a clarification in the Matrix 1.12 where the `global`
  scope is now hardcoded.
  - The `push` endpoints don't take a scope anymore.
- Make `Content-Type` and `Content-Disposition` mandatory when creating media
  responses, according to MSC2701 / MSC2702 / Matrix 1.12.
- Use `OwnedOneTimeKeyId` and `OneTimeKeyAlgorithm` instead of
  `OwnedDeviceKeyId` and `DeviceKeyAlgorithm` respectively to identify one-time
  and fallback keys and their algorithm.
- Use `OwnedCrossSigningOrDeviceSigningKeyId` instead of `OwnedDeviceKeyId` to
  identify signing keys in `BackupAlgorithm::MegolmBackupV1Curve25519AesSha2`'s
  `signatures`.
- Use `CrossSigningOrDeviceSignatures` for the `signatures` of `BackupAlgorithm`.
- Use `ServerSignatures` for the `signatures` of `ThirdPartySigned`.

  field, with a new type `SlidingSyncRoomHero`.
- Add support for authenticated media endpoints, according to MSC3916 / Matrix
  1.11.
  - They replace the newly deprecated `media::get_*` endpoints.

  Matrix 1.11
- Add unstable support for [MSC4140](https://github.com/matrix-org/matrix-spec-proposals/pull/4140)
  to send `Future` events and update `Future` events with `future_tokens`.
  (`Future` events are scheduled messages that can be controlled
  with `future_tokens` to send on demand or restart the timeout)
- Change types of `SyncRequestListFilters::{room_types,not_room_types}` to
  `Vec<RoomTypeFilter>` instead of a vector of strings
  - This is a breaking change, but only for users of `unstable-msc3575`
- Add the `get_login_token` field to `Capabilities`, according to a
  clarification in Matrix 1.12.
- Add support for account locking, according to MSC3939 / Matrix 1.12.

  `limited` or `prev_batch` fields are set.
- `login_fallback::Response` now returns the proper content type

Breaking changes:

- The conversion from `PushRule` to `ConditionalPushRule` is infallible since
  the `conditions` field is optional.
  - `MissingConditionsError` was removed.
- The `ts` field in `Request` for `get_media_preview` is now `Option`.
- The query parameter of `check_registration_token_validity` endpoint
  has been renamed from `registration_token` to `token`
- `Error` is now non-exhaustive.
- `ErrorKind::Forbidden` is now a non-exhaustive struct variant that can be
  constructed with `ErrorKind::forbidden()`.
- The `retry_after_ms` field of `ErrorKind::LimitExceeded` was renamed to
  `retry_after` and is now an `Option<RetryAfter>`, to add support for the
  Retry-After header, according to MSC4041 / Matrix 1.10

* Make `r0::uiaa::ThirdpartyIdCredentials` an owned type and remove its `Incoming` equivalent
  * Previously, we had two fields of type `&'a [ThirdpartyIdCredentials<'a>]` and this kind of

  then call `IncomingLoginInfo::to_outgoing` on it.
* Move MSC2858 - Multiple SSO Identity Providers out of the `unstable-pre-spec` feature flag, this
  includes:

* Add unstable support for reasons for leaving rooms

# 0.11.2

Yanked since it depended on a version of ruma-api that had to be yanked too.

  * Explicit types may have to be updated from `endpoint::Request` to `endpoint::Request<'_>` on
    clients and `endpoint::IncomingRequest` on servers, the other way around for responses.
  * When sending a request or response, you shouldn't have to clone things as much as before. Tip:
    Use clippy to detect now-unnecessary `.into()` conversions.
* Make most types non-exhaustive
  * This means you no longer can construct many of them using struct literals.
  * Instead, constructors are provided.

      account::request_openid_token,
      media::{get_content, get_content_as_filename, get_content_thumbnail},
      membership::join_room_by_id_or_alias,
      session::login,
  }
  ```
* Rename `r0::search::search_events::{RoomEventJsons => ResultRoomEvents}`. The previous name was an
  error introduced in a mass search and replace
* `r0::sync::sync_events::SetPresence` has been moved and renamed. Use `presence::PresenceState`
  from `ruma` or `ruma-common`.
