Parallel Releasing and Development Lines

A variant of the Parallel Maintenance and Development Lines in which the release maintenance branch is taken ahead of release. This allows the final development and test to occur without the need to freeze code in the main development codeline.



Here. the rel_1 branch is create prior to the final production of release 1.0. Once complete 1.0 is dropped into the ongoing Mainline development work. The rel_1 branch remains open and maintenance work continues to support the 1.0 release, each subsequent maintenance release being made from the branch and integrated into the ongoing Mainline branch.

This pattern is commonly used to avoid the need to freeze work on the Mainline development work that is not directly associated with the 1.0 preparation.
