WiX v3.9 Release Candidate 2

Last night the WiX v3.9 Release Candidate 2 hit the web. If you're thinking there was a release candidate only a few weeks ago, you're right. We didn't necessarily plan to release a second candidate. However, thanks to those of you tested the last release we found a few things to fix up. So, please let's do it all again. Download, install, build your world. We expect this is it. WiX v3.9 is eminent.
