Is a new release coming, since LLVM 13 was merged 2 weeks ago?

Following up on this, I’ve been trying to figure out what LLVM repo and branch I need in order to build with Cling’s master. This repo http://root.cern.ch/git/llvm.git doesn’t contain any recent branches, or any that pertain to LLVM 13. @vvassilev’s LLVM branch was claimed to be out of date here: Linkage errors with LLVM 13 - #3 by vvassilev

It seems like all of this went into root/cling master but we’re missing some documentation on how to use it. Please let me know what I’m missing!
