The newest version of the Java Development Kit 23 (JDK) has four new features in the newest release. The two major features which are noteworthy so far is the Vector API, a second preview of the Stream Gatherers, and a preview of primitive types in patterns – such as instanceof and
That's bad. 8 hasn't been getting the essential security updates since march 2022. Of course money can buy a lot, but it's still a bad idea. Even the Dutch govern.e t has mostly made the transition and they are no known for their elasticity

That's not really true despite what Oracle claims. Even without dropping money for Oracle's 2030 support, there's been 9 releases to OpenJDK 8 so far in 2024. Amazon has guaranteed OpenJDK 8 LTS through 2026 as "corretto" for justifying it to corporate compliance teams.
Everyone really should upgrade but it's going to be several years yet before it's an actual security risk.
Other features that were previewed in the Java Development Kit 22 release could also make it quite easily into the Java Development Kit 23 release. These include statements before super(…), which would give developers greater freedom in expressing constructor behavior – meaning string templates. This would make it easy to express strings that include values computed at run time – meaning scoped values. This would enable sharing of immutable data within and across threads; and implicitly declared classes and instance main methods.
