Kotlin Spark API v1.2.4 is released <https://github.com/Kotlin/kotlin-spark-api/releases/tag/v1.2.4>
It includes Java 8 support for Jupyter Notebooks as well now, plus Spark support from 3.0.0-3.3.2.
Get the version you need from maven central using this table: <https://github.com/Kotlin/kotlin-spark-api#supported-versions-of-apache-spark> as usual. If you're using Jupyter, the new version will be used automatically, or you can specify it as described here <https://github.com/Kotlin/kotlin-spark-api/wiki/Jupyter>.

Regarding Spark 3.4+, we're in a bit of a pickle. Due to changes in Spark, the API cannot simply be updated to support that version anymore. It will cost a significant amount of work to try and rebuild the base of the Kotlin Spark API from the ground up and we're investigating whether there's enough demand for it. If you have any ideas how to add support for Kotlin data classes and the inferring `encoder&lt;&gt;()` function, or you simply want to show your interest in the matter, let us know in the relevant issue: <https://github.com/Kotlin/kotlin-spark-api/issues/195>

As usual, let us know if you have any issues and enjoy the version bump :)
