The GIT branch 4.4 was created, it will host the Kamailio release series 4.4.x. To get this branch from GIT, you can use:
git clone https://github.com/kamailio/kamailio.git kamailio
cd kamailio
git checkout -b 4.4 origin/4.4
Notes about installing Kamailio from this branch are available at:
Hopefully in about two weeks or so the full release of 4.4.0 will be out.
From now on, any corresponding fix has to be pushed first to master branch and then cherry-picked to branch 4.4. No new features can get in branch 4.4. Enhancements to documentation or helping tools are still allowed.
