 * (GR-41100) Add support for `-XX:HeapDumpPath` to control where heap dumps are created.
 * (GR-42148) Adjust build output to report types (primitives, classes, interfaces, and arrays) instead of classes and revise the output schema of `-H:BuildOutputJSONFile`.
 * (GR-42375) Add `-H:±GenerateBuildArtifactsFile` option, which generates a `build-artifacts.json` file with a list of all artifacts produced by Native Image. `.build_artifacts.txt` files are now deprecated, disabled (can be re-enabled with env setting `NATIVE_IMAGE_DEPRECATED_BUILD_ARTIFACTS_TXT=true`), and will be removed in a future release.
-* (GR-34179) Improved debugging support on Windows: Debug information now includes information about Java types (contributed by Red Hat).
+* (GR-34179) Red Hat improved debugging support on Windows: Debug information now includes information about Java types.
 * (GR-41096) Support services loaded through the `java.util.ServiceLoader.ModuleServicesLookupIterator`. An example of such service is the `com.sun.jndi.rmi.registry.RegistryContextFactory`.
 * (GR-41912) The builder now generated reports for internal errors, which users can share when creating issues. By default, error reports follow the `svm_err_b_<timestamp>_pid<pid>.md` pattern and are created in the working directory. Use `-H:ErrorFile` to adjust the path or filename.
 * (GR-36951) Add [RISC-V support](https://medium.com/p/899be38eddd9) for Native Image through the LLVM backend.

 * (GR-43966) Remove analysis options -H:AnalysisStatisticsFile and -H:ImageBuildStatisticsFile. Output files are now written to fixed subdirectories relative to image location (reports/image_build_statistics.json). 
 * (GR-38414) BellSoft implemented the `MemoryPoolMXBean` for the serial and epsilon GCs.
 * (GR-40641) Dynamic linking of AWT libraries on Linux.
+* (GR-40463) Red Hat added experimental support for JMX, which can be enabled with the `--enable-monitoring` option (e.g. `--enable-monitoring=jmxclient,jmxserver`).
 
 ## Version 22.3.0
 * (GR-35721) Remove old build output style and the `-H:±BuildOutputUseNewStyle` option.
