A new, improved and updated version of Sketchup has been released. They have fixed and polished about 150 things. If you want to dive deep, you can read them all here.

Most notably though:

Fully OSX Lion compatible (YESS!)
Ruby Scripts are now easier to install with the RBZ Extension
Advanced Camera tools now a permanent part of Pro

So if you want the new bits and bytes on Windows you can to go Help> Check for updates. If you are on a Mac, go to Sketchup > Check Web for update.

I am most excited about the Mac 10.7 Lion compatibility, all of those nasty bugs are gone.
