Sean helped triage a multitude of v4 issues today, attending from the airport, mere minutes away from the start of a 14-hour reverse-time-travel adventure back to the United States. As we went to press, we can report he landed safely and is now a jet-lagged resident of the Northern Hemisphere.
Update MajorUpgrade to default to same-version upgrades, from @rseanhall, triggered a bit of a discussion. In the end, we decided that the risk of accidental downgrades due to the Windows Installer behavior of ignoring the fourth version field meant that same-version upgrades should not be the default.
Alt Text to the CancelDlg's Icon, from @roaladje, is another accessibility bug in the WixUI dialog library. We decided to create some tracking bugs to gather all the accessibility bugs in the hopes we can send up a flare asking for accessibility experts to help fix them all.
Smart Cabbing not working in some cases, from @Reelsun, reports the sad news of a potential dumbness in smart cabbing (the feature that keeps only one copy of a file that's included more than one in a package). Rob took the issue to investigate for WiX v4.0.
