+## [0.2.15] 2025-1-23
+
+* Fixed an issue where an exception could be raised if OptionsListView has lastLineText set, and dialogue begins with an option. 
+
 ## [0.2.14] 2024-11-02
 * GDScript: Add GDScriptViewAdapter, a C# Script which allows you to write custom dialogue views in GDScript. See GDScriptViewAdapter.cs for more details.
 * GDScript: Add new method AddCommandHandlerCallable to DialogueRunner, allowing commands to be registered from GDScript. GDScript command handlers that use asynchronous `await` functionality are also supported as blocking YarnSpinner commands, similar to using `async Task` commands in C#.
