+## 🎉 v0.8.0 - Major Feature Release
+
+This release includes 33 commits with significant new features, performance improvements, and architectural enhancements.
+
+### 🚀 Major Features
+
+- **`dev map` command** - Visualize codebase structure with component counts, exports, and hot paths (224x performance improvement!)
+- **`dev activity` command** - Show most active files with commit counts, recency, and complexity
+- **`dev owners` command** - Developer specialization breakdown with file-level ownership
+- **Author contribution indexing** - Indexed during `dev index` for 35x faster ownership queries
+- **Service layer architecture** - 7 services with dependency injection for better testability
+- **MetricsStore with SQLite** - Persistent code analytics with `file_authors` table
+- **Code metadata system** - Factual metrics replacing risk scoring
+- **Change frequency analysis** - Git activity tracking and hotspot identification
+- **Stats comparison & export** - Historical metrics analysis
+
+### 🎨 CLI/UX Improvements
+
+- **Compact table format** for metrics commands with factual summaries
+- **Top-level commands** - `dev activity` and `dev owners` (refactored from `dev metrics`)
+- Enhanced `dev stats` output with 10x performance boost
+- Enhanced `dev git stats` with clean, scannable format
+- Enhanced `dev compact`, `dev clean`, and MCP command outputs
+- Modernized CLI with compact, user-friendly formatting
+- Comprehensive help text with examples and use cases
+- Visual indicators (🔥 for hotspots, ✏️ for activity)
+- GitHub handle resolution for developer identification
+
+### 🏗️ Architecture & Quality
+
+- Service-oriented architecture with dependency injection
+- Circular dependency resolution via shared types package
+- Complete Zod validation across all 9 MCP adapters and external boundaries
+- Kero logger integration throughout
+- SearchService refactor for better code reuse
+- Improved error handling and messaging
+
+### ⚡ Performance Optimizations
+
+- **`dev map`**: 224x speedup (103s → 0.46s)
+  - Added `getAll()` method for fast scans without semantic search
+  - Added `skipEmbedder` option for read-only operations
+  - Added `getBasicStats()` to avoid expensive git enrichment
+- **`dev owners`**: 35x speedup (17.5s → 0.5s)
+  - Batched git operations during indexing (1 call vs N file calls)
+  - Author contributions stored in `file_authors` table
+  - Offline capability - no git access needed after indexing
+- **`dev stats`**: 10x speedup via direct JSON reads
+
+### 🐛 Bug Fixes
+
+- Fixed component count overflow in map generation (2.4B → 3.7K)
+- Fixed detailed stats persistence in indexer
+- Fixed ENOBUFS issues
+
+### 📚 Documentation
+
+- Updated website for v0.7.0 features
+- TypeScript standards with Zod validation examples
+- Workflow documentation with commit checkpoints
+- Enhanced CLI help text across all commands
+
+### 🧪 Testing
+
+- All 1,918 tests passing
+- Added comprehensive test coverage for new features
+- Mock updates for new `getAll()` method
+
+This release represents a significant step forward in usability, performance, and code quality. Special thanks to all contributors!
