+## GraalVM for JDK 25 (Internal Version 25.0.0)
+* (GR-60088): This PR adds the `org.graalvm.nativeimage.libgraal` SDK module. With this module, all logic for building
+  libgraal has been moved into the compiler suite in a new `jdk.graal.compiler.libgraal` module
+  which has no dependency on Native Image internals. This
+  is required for Galahad CE where libgraal must be buildable from the Graal compiler sources in the OpenJDK
+  while using Native Image as an external tool.
+
 ## GraalVM for JDK 24 (Internal Version 24.2.0)
 * (GR-57209): The default number of JVMCI threads is now the same as the number of C2 threads (`-XX:JVMCINativeLibraryThreadFraction=0.66`).
   This benefits the program warmup but could increase the maximum RSS.
