  This report is based on simple comparison of all public and
  protected APIs of the Java SE packages of JDK builds
  24.0.2+12-54-open and 18.0.2.1+1-tem.
  It does not make statements about
  compatibility.
For the latest Java versions the corresponding CSRs (Compatibility & Specification Review) are linked for a quick reference to find out about the reasoning of the change.
