There are lots, I mean lots, of important bugs squashed in R3.1, R3.2, and R4. Then an Apple security patch broke R4 too, including the IDE, and that’s exactly why R4 was patched as R4.1 (plus few extras)
The other side of the coin is that most of them were silly ones that could not even exist if when Xojo introduced those broken “new features” they made basic unit tests. But I’m glad they fixed what was found until now and hope that there aren’t some more lurking to explode something. R4.1 seems the most stable one from 2022.
