LTS version is upgraded to V2.10.4 to fix a bug in SIP register process. This bug is also fixed in V3.x (stable) and V4.0 versions.

Stable version is upgraded to V3.1 to include more features, such as web server, and fix bugs.

The most important thing is that V4.0 is released now! V4.0 is a cross-platform SIP server which can run on Windows and Linux (such as Ubuntu, etc)! We will give mode instruction on V4.0 in blog.
