1.0.0 - 2024-12-13 (Internal Development Version)

🔒 Security Enhancements

• Added HMAC-SHA256 session signing: Session cookies are now cryptographically signed to prevent tampering
• Changed session cookie defaults: Now use secure: true, httpOnly: true, SameSite: Lax by default
• Added constant-time signature comparison: Protection against timing attacks
• Fixed rate limiter memory leak: Cleanup timers now properly disposed on shutdown

✨ New Features

• Pluggable Session Stores: Abstract SessionStore interface for custom persistence backends
• MemorySessionStore: Built-in in-memory store with automatic TTL expiration
• Session lifecycle hooks: Automatic load/save with error handling
• sessionSecret parameter: Configure HMAC secret for production
• secureCookies parameter: Control HTTPS enforcement (default: true)
• sessionStore parameter: Use Redis, PostgreSQL, or custom backends

🔧 Bug Fixes

• Fixed cookie parser discarding empty cookie values (e.g., logout=)
• Fixed rate limiter cleanup timer memory leak
• Removed broken Session.regenerate() method (session ID is immutable)
• Added proper resource cleanup on server shutdown

💥 BREAKING CHANGES

• Session cookies now require HTTPS in production (default secure: true)
  • Set secureCookies: false for local HTTP development
  • Ensure HTTPS is configured for production deployments

Dependencies

• Added: crypto: ^3.0.3
