[screen-devel] What's the "master" branch used for in the git repo?

[Clark Wang]

Hi,

Regarding https://git.savannah.gnu.org/cgit/screen.git/refs/ -- Seems
like the official screen releases are from the "screen-v4" branch and
the "master" branch is also actively maintained (according to the git
log) but the code in "master" is quite different from "screen-v4". So
what is the "master" branch used for?

Thanks,
clark
