[comgr's] amd-stg-open [branch] is the tip of the public part of the development. The version is not entirely clear yet, but would likely be whatever ROCm 5.1 becomes, which will surely depend on llvm-14.
That reminds me. I should probably explain what the various branches mean on the public repositories for the ROCm math and communication libraries (rocBLAS, hipBLAS, rocFFT, etc.). On those repositories, you will find a number of standard branches:
Of course, everything is subject to change until a release is
actually made. There's no guarantee that changes in develop,
staging or master will end up in a particular release.
Other parts of the ROCm stack use different branching schemes.
I'm not as familiar with them, unfortunately. I think the process
is mostly the same, but the branches may have different names and
not all of them are public.
