[unreleased]

Breaking changes:

Update RoomId::parse_with_server_names bounds from Into<Cow<'_, str>> to AsRef<str> + Into<String>. While this is a breaking change, it is not expected to actually require code changes.

Improvements:

Add conversion functions for RoomIdOrAliasId
- impl From<RoomId> for RoomIdOrAliasId
- impl From<RoomAliasId> for RoomIdOrAliasId
- impl TryFrom<RoomIdOrAliasId> for RoomId
- impl TryFrom<RoomIdOrAliasId> for RoomAliasId

0.15.1

Bug fixes:

Breaking changes:

All identifiers now allocate at maximum one string (localpart and host are no longer stored separately)
- Because of this, these traits are now implemented for them and only allocate in the obvious case:
  - impl From<…Id> for String
  - impl AsRef<str> for …Id
  - impl TryFrom<Cow<'_, str>> for …Id
  - impl TryFrom<String> for …Id
  - PartialEq for Strings and string slices
- Additionally, the Hash implementations will now yield the same hashes as hashing the string representation
  - Note that hashes are generally only guaranteed consistent in the lifetime of the program though, so do not persist them!
- The hostname methods have been rename to server_name and updated to return string slices instead of &url::Host
Error::InvalidHost has been renamed to Error::InvalidServerName, because it also covers errors in the port, not just the host part section of the server name
The random identifier generation functions (Id::new) are now only available if the rand feature of this crate is enabled

Improvements:

Add support for historical uppercase MXIDs
Made all dependencies optional
- serde is the only one that is enabled by default
The user_id module is now public and contains fn localpart_is_fully_conforming
- This function can be used to determine whether a user name (the localpart of a user ID) is valid without actually constructing a full user ID first
Add UserId::parse_with_server_name

Breaking changes:

Our Minimum Supported Rust Version is now 1.36.0
- This is done in a patch version because it is only a documentation change. Practially, a new project using even ruma-identifiers 0.14 won't build out of the box on older versions of Rust because of an MSRV bump in a minor release of an indirect dependency. Using ruma-identifiers with older versions of Rust will potentially continue to work with some crates pinned to older versions, but won't be tested in CI.
