In JavaScript/HTML5 applications built with OrbiterMicro, WebSocket speeds up network communications and reduces bandwidth consumption. For complete details, read Introduction to WebSocket.
  • A new module-annotation system to ease Java module development
  • Overhauled UPC-message processing that improves server performance and stability
  • A "UPC Messages" screen in Union Admin for debugging and tuning heavily loaded servers
