 ### What versions of Apache Spark does the RAPIDS Accelerator for Apache Spark support?
 
-The RAPIDS Accelerator for Apache Spark requires version 3.0.0 or 3.0.1 of Apache Spark. Because the
-plugin replaces parts of the physical plan that Apache Spark considers to be internal the code for
-those plans can change even between bug fix releases. As a part of our process, we try to stay on
