You must have heard, Gutsy it out! Start your updating engines, in case you haven't already done so the days before the final release.
Upgrade went pretty smooth for me. Then again, I only use official reps (one exception is wine) and only a few .dep files not in any repository. One problem witnessed was right after the upgrade, I couldn't use compiz anymore. On Feisty I had been using the one supplied with Ubuntu and it worked there.
The solution was to run a single command (with root-rights) that adjusts the xorg.conf with a value that is needed by the compiz-fusion version included in Gutsy;
nvidia-xconfig --add-argb-glx-visuals -d 24Each Ubuntu release pushes the envelope a little bit more. Gutsy is certainly high on eye-candy, artwork, better font rendering and the lovely compiz make it all very beautiful to look at.
