The Liberty-for-Java Buildpack v3.54 adds Liberty runtime 188.8.131.52 as the alternate runtime and keeps 184.108.40.206 as the default runtime.
The AdoptOpenJDK Open J9 alternate JRE is updated to 11.0.10_9_openj9-0.24.0. The IBM JRE Version (8 SR 6 FP20) remains the same.
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.
