22.214.171.124 is now available.
I've flogged the 126.96.36.199 kernel hard (compiling code) for the last week or so with no hiccups. So I'd say the .39 series is in real good shape.
For everything besides Dreamplugs:
sudo ./README-PLUG-UPDATE.sh 188.8.131.52 --nandkernel (installs 184.108.40.206 to nand)
sudo ./README-DREAM-UPDATE.sh 220.127.116.11 (installs 18.104.22.168 to disk)
