JDK 21 was released on September 19, 2023! As with my previous blogs, I have compiled a list of what I think are the most interesting and useful security enhancements in this release. I have also grouped them into appropriate categories (crypto, TLS, etc) which should make it easier to find out what has changed in each specific area. The JDK 21 release notes also contain further details on these and other enhancements.
