 # Changelog
 
+## 2025-05-23 - 1.10.0 - feat(cli)
+Add --startFrom and --stopAt options to filter test files by range
+
+- Introduced CLI options --startFrom and --stopAt in ts/index.ts for selective test execution
+- Added validation to ensure provided range values are positive and startFrom is not greater than stopAt
+- Propagated file range filtering into test grouping in tstest.classes.tstest.ts, applying the range filter across serial and parallel groups
+- Updated usage messages to include the new options
+
 ## 2025-05-23 - 1.9.4 - fix(docs)
 Update documentation and configuration for legal notices and CI permissions. This commit adds a new local settings file for tool permissions, refines the legal and trademark sections in the readme, and improves glob test files with clearer log messages.
