Pretty sure it's been mentioned somewhere and I've missed it, but could anyone confirm that coroutines are indeed meant to follow kotlin versions in their semver?

[Colton Idle]

Might be a dumb question, but can I use coroutines 1.5 if I'm still on kotlin 1.4.32?

@Colton Idle Why do you want to stay on Kotlin 1.4.32?

[Colton Idle]

@louiscad compose has me tied to 1.4.32

[louiscad]

I think you can try, so long you don't use @ExperimentalTime

[Vsevolod Tolstopyatov [JB]]

@Big Chungus not really, Kotlin has different versioning (e.g. 1.4.20 -> 1.4.21 -> 1.4.30 vs coroutines 1.4.0 -> 1.4.1 -> 1.4.3). In addition, coroutines are actually allowed to introduce new non-experimental API in minor versions.
The fact that major versions of these two are the same is just a coincidence

@ArcticLampyrid it’s here 🙂

Does anyone know why org.jetbrains.kotlin:kotlin-scripting-compiler-impl-embeddable:1.5.0 depends on org.jetbrains.kotlinx:kotlinx-coroutines-core:1.3.8 and not 1.5.0 ? This force resolving dependencies for coroutines 1.5.0 in gradle to 1.4.2

update:
looks like io.spring.dependency-management force coroutine dependency version
