Hello,
Kamailio SIP Server v3.1.3 stable release is out.
This is a maintenance release of latest stable branch, 3.1, that includes fixes since release of v3.1.2. There is no change to database schema or configuration language structure. Deployments running v3.1.0, v3.1.1 or 3.1.2 are strongly recommended to be upgraded to v3.1.3.
For more details about version 3.1.3, visit: http://www.kamailio.org/w/2011/04/kamailio-v3-1-3-released/
Note: existing configuration files for installations on 64b operating systems may need to be updated to specify 'lib64' to the path where the modules are installed (to the value of parameter 'mpath'). See bottom note of the link provided above.
Cheers, Daniel
