The changes are all security related. I noticed several errrors when running with UAC turned on, so I decided to fix them. You still can't share physical drives with UAC on, but everything else works now.
The only other significant change (which I think I put in 1.9), was adding a setting to limit the number of items in the cache. I got tired of cleaning it out manually.,
Anyone who upgrades to this version should follow all the steps in the readme. Some of the changes were pretty significant, like registry keys changing locations.
