Here are some notes about features added in 0.7.2. Checking/Testing them is still useful and appreciated!

Note that the X DAMAGE feature will be on by default and so I am interested if that causes any problems. I'd also like to have the new wireframe move/resize, the wireframe copyrect translation, and the scroll detection+copyrect features all on by default as well since when they work they give a great speedup! (CopyRect is a VNC encoding and is very fast because the viewer already has the image data that needs to be copied: e.g. it just moves it to another part of its screen). The scroll copyrect is currently the least stable, you can toggle it off via "-noscr" or via the gui (all of the other new features can also be toggled by cmdline option or gui, see -help output for more info).
