After upgrade to 1.6.20 the compileKotlinMetadata or metadataMainClasses gradle tasks don't work anymore (don't try to compile common sources or even create a build directory). What has changed?

The compileCommonMainKotlinMetadata task seems to be working now.

Hi Robert!
HMPP was enabled by default in 1.6.20 https://kotlinlang.org/docs/whatsnew1620.html#hierarchical-structure-support-for-multiplatform-projects

With HMPP common code will be compiled now into KLIB format instead of legacy *.kotlin_metadata file format.
