 Your next API to work with  [Apache Spark](https://spark.apache.org/). 
 
 This project adds a missing layer of compatibility between [Kotlin](https://kotlinlang.org/) and [Apache Spark](https://spark.apache.org/).
 It allows Kotlin developers to use familiar language features such as data classes, and lambda expressions as simple expressions in curly braces or method references. 
 
-We have opened a Spark Project Improvement Proposal: [Kotlin support for Apache Spark](http://issues.apache.org/jira/browse/SPARK-32530#) to work with the community towards getting Kotlin support as a first-class citizen in Apache Spark. We encourage you to voice your opinions and participate in the discussion.
