Valve's SteamOS Compositor Has Begun Seeing Some Activity Recently

SteamOS Brewmaster hasn't seen any updates in a while (SteamOS 2.195 came out this summer with minor updates) though recently Valve's SteamOS Compositor GitHub repository did see some activity igniting hopes we could see a new release still this year... Well, it would be really great seeing a release re-based to Debian 10 "Buster" but any activity would be welcome even just pulling in all of their Linux graphics driver infrastructure updates they've funded in recent times...
