Is there some documentation stating which kotlinx serialization plugin version to use with witch Kotlin version? I can't seem to find anything in the official documentation.

[Stephan Schröder]

try if the latest version works for whatever Kotlin version you use 🤔

[Lukas K-G]

It works, yes, but is it the right thing to do given that the plugin is part of Kotlin the mono repo?

[Stephan Schröder]

it's not a mono repo: https://github.com/Kotlin/kotlinx.serialization

Do you mean kotlin("plugin.serialization") ? Because if so, you should always use the same version as the Kotlin plugin itself

[Lukas K-G]

Yes, i mean kotlin("plugin.serialization") and I figured that that's the case. But is there any documentation around that?

[CLOVIS]

I don't know. However, everything published under kotlin("plugin.xxx") is published with the same version as Kotlin itself. Same with Power Assert, Compose, etc.

[Lukas K-G]

Thanks for your help. Makes sense as those are located all here. Still trying to find some public documentation around that.

[Stephan Schröder]

several plugins including serialization are about to become part of kotlin, here's the part of the KotlinKonf2025 keynote that talks about that:

but so far it's still separate and serialization has the same number as the kotlin plugin.

Very interesting, thanks for sharing.

Plugin version always should be the exact same version and the compiler.
Otherwise there would be binary compatibility issues.

Thanks, would be great to have this somewhere in the public docs, I couldn't find it.
