A question about packaging, Guix

Hi everyone, I'm working on updating, improving the quality and maintaining the Jami package for GNU Guix.

For the purpose I need to know which version is the latest stable one from here https://dl.jami.net/ring-release/tarballs/?C=M;O=D (I would like to avoid trying to build a version with compilation errors or something like this)

Also I've been away from the project for about 5 months, because I couldn't compile Jami on my Devuan machine, so I would like to know if some radical changes have been made since then. The version packaged is from March 2019 and I need to know if anything changed since then, is there a list of Jami dependencies somewhere?
