| seo-description: Liberty now offers container images with Java 21 support using the Semeru Runtime JRE. These images use UBI 9 minimal base images and the Semeru JRE to produce smaller application images. They also now offer InstantOn support for the Power and Z (s390x) processor architectures, along with the previously supported x86-64/AMD64 processor architectures. | ||

| Liberty now offers container images with Java 21 support using the Semeru Runtime JRE. These images use UBI 9 minimal base images and the Semeru JRE to produce smaller application images. They also now offer InstantOn support for the Power and Z (s390x) processor architectures, along with the previously supported x86-64/AMD64 processor architectures. | ||

| == Universal Base Image Minimal Version 9 | ||
| The link:https://catalog.redhat.com/software/containers/ubi9/ubi-minimal/615bd9b4075b022acc111bf5[Universal Base Image 9 Minimal] is a stripped down image that uses `microdnf` as a package manager, which allows for the production of smaller application images. Open Liberty Java 21 UBI 9 minimal link:https://github.com/OpenLiberty/ci.docker/blob/main/docs/icr-images.md[images] are available starting with the 24.0.0.1 release of Open Liberty. The UBI 9 minimal content may impact some application image builds because of missing functionality. Application image builds can use `microdnf` to install additional packages as required. Unlike UBI 8, UBI 9 is not [FIPS compliant](https://access.redhat.com/articles/2918071#fips-140-2-and-fips-140-3-2) at the time of this publication. Other Open Liberty Java version images will continue to use the UBI 8 standard images (Java 8, Java 11, Java 17). | ||

| == Semeru Runtime Java 21 JRE | ||
| The high-performance link:https://developer.ibm.com/languages/java/semeru-runtimes[IBM Semeru Runtime] now supports link:https://community.ibm.com/community/user/wasdevops/blogs/tony-renaud/2024/01/11/ibm-semeru-runtime-open-edition-2101-is-out-today[Java 21], including the various Java 21 language features, such as Virtual threads, scoped values, record patterns, the latest foreign functions and memory API, and more. | ||
|
|
||
| For Java 21, the Open Liberty project now uses UBI 9 minimal images with the Semeru Runtime Java 21 JRE link:https://github.com/ibmruntimes/semeru-containers[container] images. The Semeru Runtime JRE images are considerably smaller than the JDK images. The Liberty Java 21 images provide a very nice reduction in the size of application images due to the use of the UBI 9 minimal image and the Semeru Runtime JRE image. The reduced content of the JRE image might impact some application images because of its reduced functionality. | ||

| == Liberty InstantOn support on Power and IBM Z with the Java 21 image | ||
| link:https://openliberty.io/docs/latest/instanton.html[Liberty InstantOn] support for Power and Z (s390x) require the UBI 9 based image. The Liberty Java 21 UBI 9 minimal images can now use Liberty InstantOn to achieve faster application startup on the Power and IBM Z (s390x) process architectures. Liberty InstantOn continues to support the x86-64/AMD64 process architectures with the Liberty container link:https://github.com/OpenLiberty/ci.docker/blob/main/docs/icr-images.md[images] using Java versions 11, 17 and 21. | ||
