- [`KT-57369`](https://youtrack.jetbrains.com/issue/KT-57369) K2/MPP: supertypes established in actual-classifiers from other source sets are not visible
- [`KT-55469`](https://youtrack.jetbrains.com/issue/KT-55469) [K2/N] equals(Double,Double) and equals(Boolean,Boolean) are not found
- [`KT-57250`](https://youtrack.jetbrains.com/issue/KT-57250) K2: the metadata is serialized for an `expect` class even if the `actual` class is present when compiling to klib
