El anuncio oficial:
Kamailio SIP Server v4.2.6 stable is out! This is a minor release including fixes in code and documentation since v4.2.5.
Kamailio (former OpenSER) v4.2.6 is based on the latest version of GIT branch 4.2, therefore those running previous 4.2.x versions are advised to upgrade to 4.2.6 (or to 4.3.x series). If you upgrade from older 4.2.x to 4.2.6, there is no change that has to be done to configuration file or database structure comparing with older v4.2.x.
