While checking the last pull requests on Kamailio’s Github repository, I noticed that the number of commits to master branch has just surpassed 25 000 (not counting at all commits to stable releases or personal branches). They are counted from the very first day back in September 2001, the migration to Git few years ago converted the commits from old CVS and SVN times.
While number of commits is not necessarily a metric of the quality of code, it does reveal a constant and consistent development effort performed during the past 15 years and a half, averaging over 1500 commits per year (n.r., last years with way more commits than the early one due to increase of the number of contributors).
The growth of Kamailio development isn’t slowing down at all. The last major release, Kamailio v5.0.0, was out about one month ago and since then we have 3 new modules already part of the master (topos_redis, ims_diameter_server and call_obj modules) and one is pending to be merged being now a pull request (keepalive module).
Many thanks to all developers and users that contributed to enhance the set of features, quality and stability of Kamailio over all these years!
