The window was definitely smaller than I would consider ideal. But the OSMF only applied to WiX v6 (released in April) and later. So, all the older versions would not be impacted.

Also, the timing was never raised as an issue by anyone in the community. If there had been significant pushback, I would have definitely re-evaluated the timing.

The launch went really well though.

you could stay in the last version from what i can tell
