I did the upgrade and things seem very solid and smooth........I do have what I think is a weird boot problem when booting from a cold start. It boots to the 'GhostBSD' window and hangs. On rebooting to try to find the problem I found it boots successfully when the 'verbose' option is selected.

I haven't worked on it very much but it appears also to hang when suspend or hibernate is selected. I have Ghost on a laptop and the same holds true when the lid is closed.....it won't wake up when the lid is opened again.

Clearly this doesn't affect things once your aware of it and the new release is excellent.

I followed up with a new install and this going well.....no recovery from suspend/hibernate but boots ok and WIFI works.
