Does “kotlin 1.4.21-release-Studio4.2-1” support compose?

The

-release-Studio4.2-1

means it is intended for use within AndroidStudio (not intended to be used for building), and also I'm not even sure if AndroidStudio has upgraded to 1.4.20 yet. So I'm not sure what you're trying to do there, but it sounds like funny business to me. But having said all that, if you're sure you know what you're doing... it is untested so no promises, but yes, it is intended that

alpha08

should be compatible with Kotlin

1.4.21

.

Thanks, upgraded to 1.4.21. alpha08 is compatible.
