 -   Update matrix-rust-sdk dependency to 0.9.0.
 -   Minimum supported glibc version is now `2.35` (Ubuntu 22.04+ compatible). Support has been dropped for prior versions.
+-   `RoomId` no longer has a `serverName` property, and is allowed to not have a server name component.
+    This is a breaking change.
