Kamailio SIP Server v5.5.5 stable is out – a minor release including fixes in code and documentation since v5.5.4. The configuration file and database schema compatibility is preserved, which means you don’t have to change anything to update.

Kamailio® v5.5.5 is based on the latest source code of GIT branch 5.5 and it represents the latest stable version. We recommend those running previous 5.5.x or older versions to upgrade. There is no change that has to be done to configuration file or database structure comparing with the previous releases of the v5.5 branch.

Note that 5.5 is the second last stable branch, still officially maintained by Kamailio project development team. The latest stable branch is 5.6, with v5.6.1 released out of it.
