The GNOME Developer’s Kit is still alive, thanks to Zhang Sen. My free time has been getting tight, and I am very pleased to have been getting some great help from Zhang. In fact, he is doing the daily maintenance now. I am still wrangling isos and virtual images, and Zhang is doing the daily triage of build failures (the hard work :).
Not only has he picked up the daily maintenance, but he has also converted the recipes to use git. He has also packaged gnome-shell, very cool stuff.
