branches, releases

(I am one of several who look after ham/gnuradio stuff in pkgsrc.) In gr-osmosdr, it seems 0.1.4 is the most recently release, long ago. The v0.1.4 tarball seems to build aginst gnuradio 3.7. There is a gr3.6 branch that has both many commits more than and less than the v3.6 tag. master has 127 commits beyond v0.1.4 but is not missing any. This seems odd, as I would expect gr3.6 to be based on some intermediate commit along the path from 0.1.4 to master. So I am not following what is going on and why. Now that gnuradio 3.7 seems normal, it seems there should be a release based on master, and there is no real reason for anyone to use the 3.6 branch (unless they are on a system that is intentionally using old gnuradio). Can somebody explain? With any luck I'm confused. Greg
