 # Changelog
 
+## 2025-05-26 - 2.3.0 - feat(cli)
+Add '--version' option and warn against global tstest usage in the tstest project
+
+- Introduced a new '--version' CLI flag that prints the version from package.json
+- Added logic in ts/index.ts to detect if tstest is run globally within its own project and issue a warning
+- Added .claude/settings.local.json to configure allowed permissions for various commands
+
 ## 2025-05-26 - 2.2.6 - fix(tstest)
 Improve timeout warning timer management and summary output formatting in the test runner.
