Title: Java 21™ What's new and noteworthy?

Abstract:
Hey, there are two major Java versions released every year! We don't have to wait 3 years or so for new features any more. Isn't that cool? ;-)
Java was supposed "to be slow". However, Java turns out to evolve so fast, that next releases aren't just version bumps, but might significantly change the rules of the game. That's a good reason to check out what's new in Java.
To name a few changes:
- Virtual Threads,
- Pattern Matching for switch,
- Record Patterns,
- Structured Concurrency,
- String Templates,
- what's gone and what will be gone,
- and other stuff.
If you find them interesting, let's dive deep together into new interesting stuff!
PS. Because Java 21 release is huge, this time we'll do sort of diff version. Meaning: if something was already covered in Java 20 talk https://www.youtube.com/embed/Oj-ysSgljN0 we'll focus on what has changed since then.
