Bug fixes:

* Fix key algorithm serde (de)serialization
* Fix `key_algorithms::{DeviceKeyAlgorithm, ServerKeyAlgorithm}` not implementing `Deserialize` and
  `Serialize` with `default-features = false` + `features = ["serde", …]`

Bug fixes:

* Fix `key_algorithms::{DeviceKeyAlgorithm, ServerKeyAlgorithm}` not implementing `Deserialize` and
  `Serialize` with the default feature set
  * This bug was introduced in 0.17.2
  * This problem still persists with `default-features = false` + `features = ["serde", …]`, but
    there was never a reason to use ruma-identifiers like that

Bug fixes:

* Fix `RoomVersionId::is_version_6` actually checking for version 5
* Fix `TryFrom` implementations for `RoomVersionId`, which previously returned
  `RoomVersionId::Custom` for the input `6`

ruma-serde 0.2.3

Breaking Changes:

* Replace `RoomV3Pdu` with `ruma_events::pdu::{Pdu, PduStub}`.

Improvements:

* Add endpoints:

  ```
  authorization::get_event_authorization::v1,
  membership::create_join_event::v2,
  openid::get_openid_userinfo::v1,
  query::get_profile_information::v1,
  transactions::send_transaction_message::v1,
  ```

ruma-events 0.22.0-alpha.1

ruma-common 0.2.0

Bug fixes:

* Fix deserialization of `r0::room::get_room_event::Response`
* More missing fields in `r0::sync::sync_events::Response` can be deserialized
* Fix `get_tags::Response` serialization

Breaking changes:

* Make `avatar_url` in `r0::profile::set_avatar_url::Request` an `Option`
* Update type of `canonical_alias` in `r0::directory::PublicRoomsChunk` from
  `Option<String>` to `Option<RoomAliasId>`
* Update `r0::room::create_room::CreationContent`
  * Change `federated`s type from `Option<bool>` to `bool`
  * Add `predecessor` field
* Update `r0::push::get_pushrules_all` and `r0::push::get_pushrules_global_scope` to use the
  `Ruleset` type from `ruma_common::push` (also available as `ruma::push`)
* Fix event types in `r0::context::get_context`
* Fix event types in `r0::sync::sync_events`
* Update type of `user_id` in `r0::account::whoami` from `String` to `ruma_identifiers::UserId`
* Update type of `limited` in `r0::sync::sync_events::Timeline` from `Option<bool>` to `bool`
* Use `DeviceId` for `device_id` field of `r0::session::login::Response`
* Use `ruma_identifiers::ServerName` instead of `String` for `server_name` fields in the following endpoints:
  ```rust
  r0::{
      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`.
* `r0::push::Action` has been moved. Import it from `ruma` or `ruma-common`.

Improvements:

* Add method `into_event_content` for `r0::room::create_room::CreationContent`
* Add room visibility endpoints: `r0::directory::{get_room_visibility, set_room_visibility}`.
* Add is_empty helpers for structs in `r0::sync::sync_events`
* Add a constructor for request structs of the followign endpoints
  * `r0::room::create_room`
  * `r0::message::get_message_events`
* Add `logout_devices` field to `r0::account::change_password`

Improvements:

* Upgrade dependencies
