 Breaking changes:
 
+- Add a new `error_on_verified_user_problem` property to
+  `CollectStrategy::DeviceBasedStrategy`, which, when set, causes
+  `OlmMachine::share_room_key` to fail with an error if any verified users on
+  the recipient list have unsigned devices.
+  ([#3810](https://github.com/matrix-org/matrix-rust-sdk/pull/3810))
+
 - Remove the method `OlmMachine::clear_crypto_cache()`, crypto stores are not
   supposed to have any caches anymore.
