 This changelog summarizes major changes between GraalVM SDK versions. The main focus is on APIs exported by GraalVM SDK.
 
 ## Version 22.0.0
+* (GR-31170) Native Image API: Added `WINDOWS_AARCH64` Platform.
 * (GR-33657) Native Image API: Added `CEntryPoint#include` attribute which can be used to controll if the entry point should be automatically added to the shared library.
 * (GR-22699)(EE-only) Added the ability to spawn a native-image isolate for a each `Engine` or `Context` by calling `Context.Builder.option("engine.SpawnIsolate", "true")`.  This enables heap isolation between the host and guest applications. Using isolates improves security, startup and warmup time of polyglot languages. In this mode, calls between host and guest are more costly as they need to cross a native boundary. It is recommended to use the `HostAccess.SCOPED` policy with this mode to avoid strong cyclic references between host and guest. This mode is experimental in this release and only supported for a limited set of languages.
