Hello, I'm planning to merge staging into master soon (tomorrow or friday), unless someone has a problem with it. It includes at least two CVE fixes as well as a bunch of updates such as a newer gstreamer, ffmpeg, qt 5, python-cryptography and a few others, and seems to be close to master in terms of coverage (currently 68% for staging vs 73% for master, according to https://ci.guix.gnu.org/).
I was able to reconfigure my system with it, and haven't seen issues so far. Testing welcome! -- Thanks, Maxim
