+=== Supported platforms
+
+The daemon runs on Java 17 or later.
+The `bin/mvnd` native client is built with GraalVM `native-image` for four platforms; on any other platform,
+`bin/mvnd.sh` (`bin/mvnd.cmd` on Windows) runs the Java client instead.
+The daemon also loads `mvndnative`, a small JNI library for `setenv`, `chdir` and macOS memory information,
+which is prebuilt for the platforms in the following table.
+The last column lists the Java 17 or later builds that vendors published as of October 2026.

 == Usage
 
 `mvnd` is designed to accept the same command line options like stock `mvn` (plus some extras - see below), e.g.:
