+# What's new in version 0.48.0
+
+The following new features and notable changes since version 0.47.0 are included in this release:
+
+- [New binaries and changes to supported environments](#binaries-and-supported-environments)
+- [Loading of the `zlibnx` library on AIX is disabled by default](#loading-of-the-zlibnx-library-on-aix-is-disabled-by-default)
+
+## Features and changes
+
+### Binaries and supported environments
+
+Eclipse OpenJ9&trade; release 0.48.0 supports OpenJDK 8, 11, 17, 21, and 23.
+
+To learn more about support for OpenJ9 releases, including OpenJDK levels and platform support, see [Supported environments](openj9_support.md).
+
+### Loading of the `zlibnx` library on AIX is disabled by default
+
+From release 0.25.0 onwards, `zlibNX` hardware-accelerated data compression and decompression was enabled by default on AIX&reg;. From this release onwards, loading of the `zlibnx` library on AIX is disabled by default because using `zlibNX` might cause a `ClassNotFoundException` error. You can enable adding of the `zlibNX` library by using the `-XX:+UseZlibNX` option.
+
+For more information, see [`-XX:[+|-]UseZlibNX`](xxusezlibnx.md).
+
+## Known problems and full release information
+
+To see known problems and a complete list of changes between Eclipse OpenJ9 v0.46.0 and v0.47.0 releases, see the [Release notes](https://github.com/eclipse-openj9/openj9/blob/master/doc/release-notes/0.47/0.47.md).

 ## Explanation
 
 AIX system adds the `zlibNX` library location, if available, to the `LIBPATH` variable by default. But having the `zlibNX` library directory location in the `LIBPATH` variable might cause some issues. For example, Git clone fails when executed from Java&reg; when `zlibNX` is on the `LIBPATH` in the environment.
 
-You can disable adding of the `zlibNX` library location to the `LIBPATH` variable with the `-XX:-UseZlibNX` option.
