Information about the AEAD Cipher Suites feature is missing from the JDK 8 new security features page: http://download.java.net/jdk8/docs/technotes/guides/security/enhancements-8.html . I suggest you include something similar to the suggested release notes text from JDK-7030966:

"Support AEAD algorithms: The SunJCE provider is enhanced to support AES/GCM/NoPadding cipher implementation as well as GCM algorithm parameters. And the SunJSSE provider is enhanced to support AEAD mode based cipher suites. See Oracle Providers Documentation, JEP 115."

and include links to JEP 115 and the new AEAD cipher suites that were added to the SunProviders doc.
