This document summarizes the new features and changes in version 0.7 of the Socket.IO library. Key updates include a complete API rewrite, support for multiple processes, a new messaging protocol with flags for different message types, acknowledgments between client and server, namespacing to allow multiplexing, handshake support for sessions, shared code modules between client and server, and testing on both the client and server. The release of version 0.7 is planned for this week.
