@ -8,10 +8,35 @@ Breaking changes:
* Update `parse_with_server_name`s signature (instead of `Into<String>` it now requires
`Into<Box<str>>` of the id type). This is technically a breaking change, but extremely unlikely
to affect any existing code.
* Modify identifier types to use the new `ServerName` type:
* Change signature of `new()` methods of `EventId`, `RoomId`, and `UserId` from
```rust
fn new(&str) -> Result<Self, Error>
//...
```
to
```rust
fn new(ServerNameRef<'_>) -> Self
```
* Change signature of `server_name()` for `EventId`, `RoomAliasId`, `RoomId`, `RoomIdOrAliasId`, `UserId` from
```rust
fn server_name() -> &str
```
to
```rust
fn server_name() -> ServerNameRef<'_>
```
Deprecations:
* Mark `server_name::is_valid_server_name` as deprecated in favor of `ServerName::try_from()`
Improvements:
* Add `DeviceKeyId`, `DeviceKeyAlgorithm`, `ServerKeyId`, and `ServerKeyAlgorithm`
* Add `ServerName` and `ServerNameRef` types
