Looks good so far and monodevelop seems faster. The only less-than-perfect thing I’ve noticed is that GTK# projects now seem to want to be .Net 4.0 rather than 3.5 projects. But new can’t always be bad!
The apt repository for x86 Ubuntu 11.10 is here:-
deb http://void.printf.net/~bredroll/pmono ./
You can install/update everything by doing:-
sudo apt-get update sudo apt-get install pmono-*
