 # [unreleased]
 
+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.
+
+# 0.19.0
+
 Breaking changes:
 
 - `RoomSummary::heroes` now properly contains only `UserId` instead of `String`
