1.5.1-native-mt is going to be ready around Monday

[John O'Reilly]

@Vsevolod Tolstopyatov [JB] Just to confirm...looks like this depends on use of Kotlin 1.5.20 (at least for K/N)?

[John O'Reilly]

If so, then I think apps using Jetpack Compose for example will likely need to wait until that supports 1.5.20...

[Vsevolod Tolstopyatov [JB]]

In general, all minor versions of Kotlin can be used interchangeably as long as no experimental API is involved.

Jetpack Compose users can use 1.5.1 coroutines and 1.5.0 Kotlin as long as no experimental (e.g. @ExperimentalTime) API is used

[John O'Reilly]

I ran in to issues pulling in Kotlinx Serialization 1.2.2 (which also now depends on 1.5.20) in a project that was using 1.5.10 (as Compose depends on right now)....at least for iOS build

[John O'Reilly]

so thought maybe same issue here

[John O'Reilly]

"Incompatible abi version" error in that case

[John O'Reilly]

so not directly an issue with Jetpack Compose....more indirectly in that Compose requires use of Kotlin 1.5.10 right now....and issues then doing Kotlin/Native builds using for example Kotlinx Serialization 1.2.2 (that uses Kotlin 1.5.20 now)....I updated to 1.5.20 in project just to confirm the issue with iOS build was resolved and it was (but then Compose won't work using that Kotlin version right now)

Same boat here. Added wrinkle, trying to get watchosX64 working too…
