The epsos project has decided to split itself into epsos1 and epsos2, which are not compatible in their technical implementations. OpenNCP plans to develop the epsos2 services, while still have maintenance versions of the epsos1 services.
In git, the solution will be to have the 2.x development in the develop branch, and the 1.x legacy version in a maintenance branch. Practically, we currently have this setup:
When 1.1.1 is released, the git-flow model dictates that the release branch is closed, and merged into master and then develop. The next release (1.1.2) would then branch off develop and continue as a (temporary) release branch. However, then 2.x work has already been committed to the develop branch, so we need to create a legacy branch off either the 1.1.1 release branch, or the master branch just after the 1.1.1 release branch has merged into that.
This will result in the git repositories having a 1.1 maintenance branch and the normal master, develop and release and feature (not show in diagram) branches:
