This is a bug fix release where we addressed as many of the issues found in the first release candidate as possible. The net result is pretty good leaving only a couple VS template related problems. Or so we think. Your validation will help us know for sure.
So, I encourage you to go to the WiX Toolset Downloads page and checkout the new recommended build. Report any issues you see. At this point, barring unforseen issues, I expect WiX v3.11 to be released early May.
In the meantime, keep coding. You know I am!
