Spark runs on both Windows and UNIX-like systems (e.g. Linux, Mac OS), and it
should run on any platform that runs a supported version of Java. This should
include JVMs on x86_64 and ARM64. It's easy to run locally on one machine ---
all you need is to have `java` installed on your system `PATH`, or the
`JAVA_HOME` environment variable pointing to a Java installation.
-Spark runs on Java 17/21, Scala 2.13, Python 3.10+, and R 3.5+ (Deprecated).
+Spark runs on Java 17/21/25, Scala 2.13, Python 3.10+, and R 3.5+ (Deprecated).
+Java 25 prior to version 25.0.3 support is deprecated as of Spark 4.2.0.
When using the Scala API, it is necessary for applications to use the same
version of Scala that Spark was compiled for. Since Spark 4.0.0, it's Scala
2.13.
