   - master: this is the default branch and is the most up to date that will eventually make the next release. This is the branch used to produce release artifacts.
   - next_release: this branch may appear temporarily when a lot of feature branches need to be merged together before being merged to master for the next release. This avoids polluting the master branch with versions that are not mature enough or may break.
   - feature-nnn: feature branches are current developments related to issue nnn when these developments are made publicly available before being merged to master or next_release
-  - v5: this was SDRangel version 5 and used to be the tip of development before merge back to master into v6. It is kept for reference in case something is found missing in the now master branch
