@@ -45,7 +45,6 @@ Java 8 prior to version 8u362 support is deprecated as of 
Spark 3.4.0.
 When using the Scala API, it is necessary for applications to use the same 
version of Scala that Spark was compiled for.
 For example, when using Scala 2.13, use Spark compiled for 2.13, and compile 
code/applications for Scala 2.13 as well.
 
-For Python 3.9, Arrow optimization and pandas UDFs might not work due to the 
supported Python versions in Apache Arrow. Please refer to the latest [Python 
Compatibility](https://arrow.apache.org/docs/python/install.html#python-compatibility)
 page.
 For Java 11, `-Dio.netty.tryReflectionSetAccessible=true` is required 
additionally for Apache Arrow library. This prevents 
`java.lang.UnsupportedOperationException: sun.misc.Unsafe or 
java.nio.DirectByteBuffer.(long, int) not available` when Apache Arrow uses 
Netty internally.
