This release provides many bugfixes and speedups, including some pretty major changes such as a new wrapper around pthreads to completely eliminate deadlock issues (soft locks). New features include the addition of a password callback handler to allow integration into your own password system, name policies, and group passwords. A basic STUN server has been added. The STUN system is to be considered a work in progress but should be usable. This release is not protocol compatible with earlier releases.
