24*4882a593SmuzhiyunEach release cycle consist of two months of development on the +master+
25*4882a593Smuzhiyunbranch and one month stabilization before the release is made.  During

27*4882a593Smuzhiyun
28*4882a593SmuzhiyunThe stabilization phase starts with tagging +-rc1+, and every week until

31*4882a593SmuzhiyunTo handle new features and version bumps during the stabilization phase,
32*4882a593Smuzhiyuna +next+ branch may be created for these features.  Once the current
33*4882a593Smuzhiyunrelease has been made, the +next+ branch is merged into +master+ and
34*4882a593Smuzhiyunthe development cycle for the next release continues there.
