Java 21 the new Java LTS (Long Term Support) is out and as a tribute to it I wanted to write a blog about it on the 21th day of Blogtober. What is new and which features are in it for me as a developer? I’ve taken a look at the release note from java release 18, 19, 20 and 21 and here is small summary of some new features. In this blog I only cover final released features and will exclude the features that are in preview or incubator.
