220.127.116.11 is now available.
I've flogged the 18.104.22.168 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 22.214.171.124 --nandkernel (installs 126.96.36.199 to nand)
sudo ./README-DREAM-UPDATE.sh 188.8.131.52 (installs 184.108.40.206 to disk)
Kernel and modules are available from the following locations:http://www.plugapps.com/mirror/with-linux/http://sheeva.with-linux.com/sheeva/
