I believe two changes need to be documented in the release notes:

1. In the recurring section on Red Hat build specific features, the use of system libraries should only refer to RPMs of java-1.8.0-openjdk & java-11-openjdk for RHEL 7.9. All builds in RHEL 8 & 9 and the builds on the customer portal will use in-tree libraries, following OPENJDK-4117

2. For this release only, we should make RHEL 8.2 users aware that they may find OpenJDK's FIPS mode becomes enabled if they are running their system in FIPS mode. On RHEL 8.2, the default for the com.redhat.fips property was false, whereas use of the same build as later RHEL versions will switch this to true by default. To retain the old behaviour, it will be necessary to pass -Dcom.redhat.fips=false
