The Kamailio SIP Server v4.1.9  stable version  is released. This is a minor release including fixes in code and documentation since v4.1.8 – configuration file and database compatibility is preserved within 4.1.x series. 

Important Note: branch 4.1 is not going to be packaged anymore, v4.1.9 being the last version to be released from this branch, marking the end of the official maintenance for 4.1.x series.

The current latest stable branch is 4.3, at this time with v4.3.4 being released out of it. The project is officially maintaining the last two stable branches, these are now 4.3 and 4.2. Therefore it is recommended to upgrade to latest 4.3.x – be aware that you may need to change the configuration file from 4.1.x to 4.2.x or 4.3.x.
