Data Source

This report is based on simple comparison of all public and protected APIs of the Java SE packages of JDK builds 14.0.2+12-adpt and 13.0.2+8-adpt. 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.
