Release life cycle

The Gluon maintainers are releasing new versions on an irregular schedule, depending on the state of the master branch concerning the stability of new features and OpenWrt updates.

Minor releases appear in each of the supported branches on a regular basis, carrying backported fixes and updates to the OpenWrt base (kernel updates and bugfixes).

The support for a release usually ends some time after the next major release. Exceptions to the rule do exist.
