+## [0.23.0] - 2026-01-07
+
+### Added (0.23.0)
+
+- **Import Command Performance Optimizations**: Major performance improvements for large codebases
+  - **Pre-computed Caches**: AST parsing and file hashes are pre-computed once before parallel processing (5-15x faster)
+  - **Function Mapping Cache**: Function names are extracted once per file and cached for reuse
+  - **Optimized for Large Codebases**: Handles 3000+ features efficiently (6-15 minutes vs 90+ minutes previously)
+  - **Progress Reporting**: Real-time progress bars for feature analysis, source linking, and contract extraction
+  - **Early Save Checkpoint**: Features are saved immediately after initial analysis to prevent data loss on interruption
+  - **Feature Validation**: Automatic validation of existing features when resuming imports
+    - Detects orphaned features (all source files missing)
+    - Identifies invalid features (some files missing or structure issues)
+    - Reports validation results with actionable tips
+  - **Re-validation Flag**: `--revalidate-features` flag to force re-analysis even if files haven't changed
+    - Useful when analysis logic improves or confidence threshold changes
+    - Forces full codebase analysis regardless of incremental change detection
+
+### Changed (0.23.0)
+
+- **Import Command Performance**: Source file linking is now 5-15x faster for large codebases
+  - Pre-computes all AST parsing before parallel processing
+  - Caches file hashes to avoid repeated computation
+  - Optimized matching logic with pre-computed feature title words
+- **Import Command Progress**: Enhanced progress reporting with detailed status messages
+  - Shows feature count, themes, and stories during analysis
+  - Real-time progress bars for source file linking
+  - Clear checkpoint messages when features are saved
+  - **Enhanced Analysis Setup**: Added spinner progress for file discovery (`repo.rglob("*.py")`), filtering, and hash collection phases
+    - Eliminates 30-60 second silent wait periods during file discovery
+    - Shows real-time status: "Preparing enhanced analysis..." → "Discovering Python files..." → "Filtering X files..." → "Ready to analyze X files"
+  - **Contract Loading**: Added progress bar for parallel YAML contract loading
+    - Shows "Loading X existing contract(s)..." with completion count
+    - Provides visibility during potentially slow contract file I/O operations
+  - **Enrichment Context Operations**: Added spinner progress for hash comparison, context building, and file writing
+    - Shows progress during hash comparison (reading existing file, building temp context)
+    - Shows progress during context building (iterating through features and contracts)
+    - Shows progress during markdown conversion and file writing
+  - **Incremental Change Detection**: Improved progress feedback with completion status message
+  - **Changed File Collection**: Added status message during file path collection
+
+### Documentation (0.23.0)
+
+- **Import Features Guide**: New comprehensive guide `docs/guides/import-features.md`
+  - Progress reporting details
+  - Feature validation explanation
+  - Early save checkpoint benefits
+  - Performance optimization details
+  - Re-validation flag usage
+  - Best practices for large codebases
+  - Troubleshooting tips
+- **Command Reference**: Updated `docs/reference/commands.md` with new `--revalidate-features` flag
+- **Quick Examples**: Updated `docs/examples/quick-examples.md` with new import features
+- **README**: Updated timing information and checkpoint details
+
+### Fixed (0.23.0)
+
+- **Linting Errors**: Fixed unused `progress_columns` variable warnings in enrichment context functions
+  - Prefixed unused variables with underscore (`_progress_columns`) to indicate intentional non-usage
+  - All linting checks now pass without errors

 **That's it!** SpecFact will extract features and stories from your code, find missing tests and contracts, and generate a plan bundle you can enforce.

+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
