Since we released WiX v3.9 RC1 back in July, the final release has always been “just a few weeks away.” That’s still true. However, as each of those weeks has passed, you have discovered and reported to the WiX issue tracker a number of bugs serious enough to prevent us from shipping.
As the bugs were regressions, mostly in Burn, in areas that received bug fixes and feature enhancements, we decided it was better to push out the v3.9 release date to give plenty of “bake time” for those changes.
Aside: We call it bake time but that’s not a really good metaphor. It’s more like pie cooling-off time, grilled meat resting time, and probably other similar things that people who actually cook or bake can tell you about.
We’re now looking at Halloween as the release date for WiX v3.9 RTM. 31-October is two months out which feels like a long time but gives us a buffer for any other lurking bugs.
