The Liberty-for-Java Buildpack v3.63 adds Liberty runtime 188.8.131.52 as the alternate runtime and keeps 184.108.40.206 as the default runtime.
The IBM JRE Version 8 SR6 FP36 remains the same. The Liberty buildpack is now including the IBM Semeru Runtime Open Edition for Java 11 (11.0.12_7_openj9-0.27.0) and is replacing the runtime from Eclipse.
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.
An existing application will not be affected by the new buildpack until you redeploy or restage it. After redeployment, existing applications should continue to run "as is" without any additional changes. New applications will automatically use the new buildpack.
