The Liberty-for-Java buildpack v3.41 now includes Liberty Runtime 20.0.0.2 as an alternate runtime, IBM Small Footprint JRE 8.0.6.5, and OpenJ9-0.18.1 JDK.

This buildpack contains two production versions of Liberty—a default version that remains constant for approximately three months and the latest version as an alternate. In this new buildpack, the default version is 19.0.0.12 and the alternate version is 20.0.0.2. To use the alternate version of Liberty follow these instructions.

An existing application will not be affected by the new buildpack until you redeploy it. After your redeployment, existing applications should continue to run “as is” without any additional changes. New applications will automatically use the new buildpack.
