Current state: - Unified augmentation system to BrainyAugmentation interface - Changed methods to specific noun/verb naming (addNoun, getNoun, etc) - Made old methods private - Combined getNouns into single unified method - Neural API exists and is complete - Triple Intelligence uses correct Brainy operators (not MongoDB) Issues identified: - Documentation incorrectly shows MongoDB operators (code is correct) - Need to ensure all features are properly exposed - Need to verify nothing was lost in simplification This commit serves as a rollback point before applying fixes.

## [2.0.0] - 2024-08-22
|
|
|
|
### 🚀 Major Features
|
|
|
|
#### Triple Intelligence Engine
|
|
- **NEW**: Unified query system combining vector similarity, graph relationships, and field filtering
|
|
- **NEW**: Cross-intelligence optimization - queries automatically use the most efficient combination
|
|
- **NEW**: Natural language query processing with intent recognition
|
|
|
|
#### Advanced Indexing Systems
|
|
- **NEW**: HNSW indexing for sub-millisecond vector search
|
|
- **NEW**: Field indexing with O(1) metadata lookups
|
|
- **NEW**: Graph pathfinding with multiple algorithms (Dijkstra, PageRank, BFS/DFS)
|
|
- **NEW**: Metadata index manager for intelligent query optimization
|
|
|
|
#### Storage & Performance
|
|
- **NEW**: Universal storage adapters (FileSystem, S3, OPFS, Memory)
|
|
- **NEW**: Smart caching with LRU and intelligent cache invalidation
|
|
- **NEW**: Streaming data processing for large datasets
|
|
- **NEW**: Write-Ahead Logging (WAL) for data integrity
|
|
|
|
#### Developer Experience
|
|
- **NEW**: Comprehensive CLI with interactive mode
|
|
- **NEW**: Brain Patterns Query Language (MongoDB-compatible syntax)
|
|
- **NEW**: 220 embedded natural language patterns for query understanding
|
|
- **NEW**: Full TypeScript support with advanced type definitions
|
|
|
|
### 🔧 API Changes
|
|
|
|
#### Breaking Changes
|
|
- **CHANGED**: `search()` now returns `{id, score, content, metadata}` objects instead of arrays
|
|
- **CHANGED**: Storage configuration moved to `storage` option in constructor
|
|
- **CHANGED**: Vector search results include similarity scores as objects
|
|
- **CHANGED**: Metadata filtering uses new optimized field indexes
|
|
|
|
#### New APIs
|
|
- **ADDED**: `brain.find()` - MongoDB-style queries with semantic extensions
|
|
- **ADDED**: `brain.cluster()` - Semantic clustering functionality
|
|
- **ADDED**: `brain.findRelated()` - Relationship discovery and traversal
|
|
- **ADDED**: `brain.statistics()` - Performance and usage analytics
|
|
|
|
### 🏗️ Architecture
|
|
|
|
#### Core Systems
|
|
- **NEW**: Triple Intelligence architecture unifying three search paradigms
|
|
- **NEW**: Augmentation system for extensible functionality
|
|
- **NEW**: Entity registry for intelligent data deduplication
|
|
- **NEW**: Pipeline processing for complex data transformations
|
|
|
|
#### Performance Optimizations
|
|
- **IMPROVED**: 10x faster metadata filtering using specialized indexes
|
|
- **IMPROVED**: Memory usage optimization with embedded patterns
|
|
- **IMPROVED**: Query optimization with smart execution planning
|
|
- **IMPROVED**: Batch processing for high-throughput scenarios
|
|
|
|
### 📚 Documentation & Testing
|
|
- **NEW**: Comprehensive test suite with 50+ tests covering all features
|
|
- **NEW**: Professional documentation with clear examples
|
|
- **NEW**: Migration guide for 1.x users
|
|
- **NEW**: API reference with TypeScript signatures
|
|
|
|
### 🐛 Bug Fixes
|
|
- **FIXED**: Memory leaks in pattern matching system
|
|
- **FIXED**: Vector dimension mismatches in multi-model scenarios
|
|
- **FIXED**: Infinite recursion in graph traversal edge cases
|
|
- **FIXED**: Race conditions in concurrent access scenarios
|
|
- **FIXED**: Edge cases in field filtering with complex nested queries
|
|
|
|
### 💔 Removed
|
|
- **REMOVED**: Legacy query history (replaced with LRU cache)
|
|
- **REMOVED**: Deprecated 1.x storage format (auto-migration provided)
|
|
- **REMOVED**: Debug logging in production builds
