AI Summary

This release introduces a robust Memory Compression Engine to reduce token usage and latency, alongside a VS Code extension that integrates with popular AI tools. It also enhances security with API authentication and rate limiting while optimizing performance through caching and event deduplication.

Key Highlights

Memory Compression Engine with 5 algorithms (whitespace, filler, semantic, aggressive, balanced)
VS Code Extension with AI Auto-Link (supports Cursor, Claude, Windsurf, Copilot, Codex)
Performance optimizations including ESH (Event Signature Hash) and MVC (Micro-Vector Cache)
API Authentication with rate limiting middleware

New Features

Memory Compression Engine (auto-select, batch compression, live metrics)
VS Code Extension (HTTP/MCP mode toggle, zero-config setup)
API Authentication (key-based, timing-safe comparison)
CI/CD GitHub Action for Docker build testing

Full Release Notes

# Changelog

### Added

- **Memory Compression Engine**: Auto-compresses chat/memory content to reduce tokens and latency

  - 5 compression algorithms: whitespace, filler, semantic, aggressive, balanced
  - Auto-selects optimal algorithm based on content analysis
  - Batch compression support for multiple texts
  - Live savings metrics (tokens saved, latency reduction, compression ratio)
  - Real-time statistics tracking across all compressions
  - Integrated into memory storage with automatic compression
  - REST API endpoints: `/api/compression/compress`, `/api/compression/batch`, `/api/compression/analyze`, `/api/compression/stats`
  - Example usage in `examples/backend/compression-examples.mjs`

- **VS Code Extension with AI Auto-Link**

  - Auto-links OpenMemory to 6 AI tools: Cursor, Claude, Windsurf, GitHub Copilot, Codex
  - Dual mode support: Direct HTTP or MCP (Model Context Protocol)
  - Status bar UI with clickable menu for easy control
  - Toggle between HTTP/MCP mode in real-time
  - Zero-config setup - automatically detects backend and writes configs
  - Performance optimizations:
    - **ESH (Event Signature Hash)**: Deduplicates ~70% redundant saves
    - **HCR (Hybrid Context Recall)**: Sub-80ms queries with sector filtering
    - **MVC (Micro-Vector Cache)**: 32-entry LRU cache saves ~60% embedding calls
  - Settings for backend URL, API key, MCP mode toggle
  - Postinstall script for automatic setup

- **API Authentication & Security**

  - API key authentication with timing-safe comparison
  - Rate limiting middleware (configurable, default 100 req/min)
  - Compact 75-line auth implementation
  - Environment-based configuration

- **CI/CD**
  - GitHub Action for automated Docker build testing
  - Ensures Docker images build successfully on every push

### Changed

- Optimized all compression code for maximum efficiency
