Hello,
Kamailio (OpenSER) version 1.5.5 is released. This is a maintenance release of branch 1.5, the last in its series.
The project is officially maintaining the latest two stable branches, these being now 3.0.x and 3.1.x. As it happened in the past, fixes can still get into SVN branch 1.5, but there is no plan to package another version 1.5.x.
If you still run 1.5.x, it is highly recommended that you start to plan the migration to 3.x versions.
For more details about version 1.5.5, visit: http://www.kamailio.org/w/2010/10/kamailio-v1-5-5-released/
Cheers, Daniel
