+## [Unreleased]
+### Fixed
+- The editor debugger should no longer cause compile errors when the game is exported. These errors were actually harmless but would give the impression that something is broken ([#74](https://github.com/derkork/godot-statecharts/issues/74)).

 ## [0.12.0] - 2024-01-12
 ### Added
 - The inspector for transitions now provides a list of all events currently used in the state chart from which an event can be selected. This minimizes the risk of typos when entering event names ([#72](https://github.com/derkork/godot-statecharts/issues/72)).
