# Release Notes - v1.9.0 **Release Date**: September 19, 2025 **Type**: Minor Release **Codename**: Memory Milestone ## 🎉 Highlights We're excited to announce v1.9.0 of DollhouseMCP, featuring the highly anticipated **Memory element type**! This release marks a major milestone with PR #1000, introducing persistent context storage with enterprise-grade scalability and security features. ## ✨ New Features ### Memory Element Implementation 🧠 The Memory element provides persistent context storage with advanced features: - **Smart Organization**: Automatic date-based folder structure (YYYY-MM-DD) prevents performance issues at scale - **Deduplication**: SHA-256 content hashing prevents duplicate storage - **Fast Search**: Built-in indexing for queries across thousands of entries - **Privacy Controls**: Three-tier privacy levels (private, team, public) - **Retention Policies**: Automatic cleanup based on age and capacity - **Tag System**: Organize and find memories with flexible tagging - **Rich Metadata**: Track statistics, timestamps, and context ### Performance Enhancements ⚡ - 60-second cache for date folder operations - Atomic file operations prevent corruption - Efficient collision handling with version suffixes - Optimized search indexing for large datasets ### Security Improvements 🔒 - Comprehensive input validation and sanitization - Security event audit logging throughout - Memory size limits to prevent DoS attacks - Content hash verification for integrity ## 📊 Technical Details ### Memory Storage Structure ``` ~/.dollhouse/portfolio/memories/ ├── 2025-09-18/ │ └── project-context.yaml ├── 2025-09-19/ │ ├── meeting-notes.yaml │ └── code-review.yaml ``` ### Key Capabilities - Add unlimited entries per memory (with configurable limits) - Search by content, tags, or metadata - Automatic retention policy enforcement - Statistics tracking (size, count, dates) - Multiple storage backends (file system now, database support planned) ## 🐛 Bug Fixes - Fixed CI test conflicts with GitHub integration tests (#1001) - Resolved race conditions in concurrent file operations - Fixed Unicode normalization issues in memory content ## 🔄 Changes - Memory files now save to date-based folders instead of flat directory - Content deduplication enabled by default - Search indexing triggers automatically at 100+ entries ## ⚠️ Known Issues - Prototype pollution warnings in ConfigManager (low priority, main branch only) - Memory encryption not yet implemented (planned for v2.0) ## 📈 Statistics - **89 tests** for memory functionality alone - **100% pass rate** on all CI workflows - **2 major PRs** merged (#1000, #1001) - **3+ issues** resolved or advanced ## 🚀 Getting Started with Memories ### Create a Memory ```typescript import { Memory } from '@dollhousemcp/mcp-server'; const memory = new Memory({ name: 'project-context', description: 'Context for my project', tags: ['project', 'important'] }); // Add entries await memory.addEntry('Design decision: Use TypeScript', ['decision', 'architecture']); await memory.addEntry('Meeting notes from standup', ['meeting', 'daily']); ``` ### Search Memories ```typescript // Search by content const results = await memory.search({ query: 'TypeScript' }); // Search by tags const meetings = await memory.search({ tags: ['meeting'] }); ``` ## 💻 Installation ```bash npm install @dollhousemcp/mcp-server@1.9.0 ``` ## 📋 Migration No migration needed - Memories are a new feature with no existing data. ## 🙏 Acknowledgments Special thanks to everyone who contributed to this milestone release, especially reaching PR #1000! ## 📝 Full Changelog For a complete list of changes, see the [full changelog](https://github.com/DollhouseMCP/mcp-server/compare/v1.8.1...v1.9.0). ## 🔮 What's Next - **v2.0.0**: Memory encryption and cloud sync - **v1.10.0**: Enhanced search with fuzzy matching - **v1.11.0**: Memory templates and presets --- **Note**: This is an MVP release of the Memory feature.
