+
+## [5.14.0] - 2026-01-21
+
+### Added - Quarto Workflow Phase 2 Complete
+
+**Status:** ✅ Production Ready - All 322 tests passing (100%)
+
+Phase 2 delivers substantial performance improvements and extensibility features for teaching workflow:
+
+- **3-10x Speedup**: Parallel rendering with worker pool architecture
+- **Custom Validators**: Extensible plugin system for content validation
+- **Cache Analysis**: Comprehensive cache management and optimization
+- **Performance Monitoring**: Automatic metrics tracking with trend analysis
+
+**Test Coverage:**
+
+- 322 new Phase 2 tests (100% passing)
+- 7 comprehensive test suites
+- Integration tests covering full workflows
+
+**Documentation:**
+
+- 2,931-line comprehensive guide
+- Quick reference card for Phase 2 features
+- API documentation for all new modules
+
+See `docs/guides/QUARTO-WORKFLOW-PHASE-2-GUIDE.md` for complete details.
+
+### Fixed - PR #277 (Phase 1 Integration)
+
+- **Dependency Scanning**: Fixed portability issues with glob patterns and sed operations
+  - Changed from `**/*.qmd` glob to `find` command for better compatibility
+  - Fixed macOS sed edge cases when inserting at/past EOF
+  - Added smart detection for append vs insert operations
+- **Test Isolation**: Fixed Test 17 failure due to file state pollution from Test 14
+- **Hook Integration**: Added `teach hooks` command routing to dispatcher
+  - `teach hooks install` - Install git hooks
+  - `teach hooks upgrade` - Upgrade to latest version
+  - `teach hooks status` - Check installation status
+  - `teach hooks uninstall` - Remove hooks
+- **Backup Path Resolution**: Added smart fuzzy matching for backup restoration
+  - Supports full paths, exact matches, and fuzzy matching
+  - Multiple match detection with clear errors
+  - Lists available backups when path not found
+
+### Fixed - Universal Flags Validation
 
 - **teach slides/exam/quiz/assignment** - Universal flags (`--week`, `--topic`, `--style`, etc.) were incorrectly rejected by flag validation. The `_teach_validate_flags` function now includes `TEACH_CONTENT_FLAGS` and `TEACH_SELECTION_FLAGS` alongside command-specific flags.
