 - Updated all file references and paths to point to single source of truth in capabilities/testdrive-jsui/js/controls/ directory
 
 ### Fixed
+- **Version Detection Issue**: Fixed `markitect --version` returning "unknown" instead of actual version
+  - Added `git_describe_command` to setuptools-scm configuration to filter version tags correctly
+  - Configured git describe to use `--match 'v*'` pattern to ignore non-version tags
+  - Version detection now works correctly with development versions (e.g., 0.9.1.dev76)
+- **Missing v0.9.0 Git Tag**: Retroactively created v0.9.0 annotated tag on commit b9c1b90 from 2025-11-14
+  - Maintains version history integrity (CHANGELOG documented v0.9.0 but tag was missing)
+  - Enables proper version progression to v0.10.0
 - Duplicate file structure issue by eliminating duplicate control files and consolidating to capabilities/ directory
 - Contents panel scrollbar behavior - moved overflow-y: auto to correct container level so scrollbar only spans content area when panel reaches max-height
