I did the update and all my software works well, Canola, Omweather (still have to manually update), Rapsody, Claws mail, minimo, Gizmo. I haven't tried the VPNC yet. The system is quicker and seems more responsive.

I am an "end-user" kind of person not much into code/terminal level hacks and I think the update went quite smoothly, at least smoother than my failed attempt at a Vista upgrade. I don't have SDHC cards so I am quite happy with the new firmware.

I would recommend it to everyone apart from SDHC users (obviously). There are enough fixes on it to make it worth while.
