🎉 Major Release - Triple Intelligence™ Engine

This release represents a complete evolution of Brainy with groundbreaking features and performance improvements.

Added

  • Triple Intelligence™ Engine: Unified Vector + Metadata + Graph search in one API
  • Natural Language Processing: 220+ pre-computed NLP patterns for instant understanding
  • Universal Memory Manager: Worker-based embeddings with automatic memory management
  • Zero Configuration: Everything works instantly with no setup required
  • Brain Cloud Integration: Connect to soulcraft.com for team sync and persistent memory
  • Augmentation System: 19 production-ready augmentations for extended capabilities
  • CLI Enhancements: Complete command-line interface with all API methods
  • New find() API: Natural language queries with context understanding
  • OPFS Storage: Browser-native storage support
  • S3 Storage: Production-ready cloud storage adapter
  • Graph Relationships: Navigate connected knowledge with addVerb()
  • Cursor Pagination: Efficient handling of large result sets
  • Automatic Caching: Intelligent result and embedding caching

Changed

  • API Consolidation: 15+ search methods → 2 clean APIs (search() and find())
  • Search Signature: From search(query, limit, options) to search(query, options)
  • Result Format: Now returns full objects with id, score, content, and metadata
  • Storage Configuration: Moved under storage option with type-specific settings
  • Performance: O(log n) metadata filtering with binary search
  • Memory Usage: Reduced from 200MB to 24MB baseline
  • Search Latency: Improved from 50ms to 3ms average

Fixed

  • Circular dependency in Triple Intelligence system
  • Memory leaks in embedding generation
  • Worker thread communication timeouts
  • Metadata index performance bottlenecks
  • TypeScript compilation errors (153 → 0)
  • Storage adapter consistency issues

Deprecated

  • Individual search methods (searchByVector, searchByNounTypes, etc.)
  • Three-parameter search signature
  • Direct storage type configuration

Removed

  • Legacy delegation pattern
  • Redundant search method implementations
  • Unused dependencies

Security

  • Improved input sanitization
  • Safe metadata filtering
  • Secure storage adapter implementations
