K2

[mgroth0]

Is there any branch or PR working on a K2 update? I started working on this and it seems like a heavy task so I'm wondering if anyone else has started.

We'll update KSP plugin and it should be enough for library users to use dataframe in their K2 builds as a dependency. As for updating to K2 compiler in our project itself, no one has started working on it yet.

There's also the Jupyter dependency. Atm Jupyter tests don't run if we compile the integration classes with Kotlin 2.0. I hope this will work once it is not in preview anymore, but I'm not sure.

Edit: From Kotlin 2.0.0-RC1 upwards, in theory, Jupyter tests work :)

It's important to note that DataFrame will likely work fine as a library in your Kotlin 2.0+ project btw, as Kotlin is inherently backwards compatible.
