+## [2023-04-24]
+
+### Breaking changes
+
+- `Plugin::editor()` and `Plugin::task_executor()` now take `&mut self` instead
+  of `&self` to make it easier to move data into these functions without
+  involving interior mutability.
+
+### Changed
+
+- The `Plugin` trait's documentation has been updated to better clarify the
+  structure and to more explicitly mention that the non-lifecycle methods are
+  called once immediately after creating the plugin object.
+
 ## [2023-04-22]
 
 ### Added
