This changelog summarizes major changes to GraalVM Native Image.

## GraalVM for JDK 25
* (GR-58668) Enabled [Whole-Program Sparse Conditional Constant Propagation (WP-SCCP)](https://github.com/oracle/graal/pull/9821) by default, improving the precision of points-to analysis in Native Image. This optimization enhances static analysis accuracy and scalability, potentially reducing the size of the final native binary.

## GraalVM for JDK 24 (Internal Version 24.2.0)
* (GR-59717) Added `DuringSetupAccess.registerObjectReachabilityHandler` to allow registering a callback that is executed when an object of a specified type is marked as reachable during heap scanning.
* (GR-55708) (Alibaba contribution) Support for running premain methods of Java agents at runtime as an experimental feature. At build time, `-H:PremainClasses` is used to set the premain classes.
