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