JDK 21: The New LT Support Version

With only six months between releases of the Java platform, it is not practical to provide extended support and maintenance for all versions. This is why all OpenJDK distributions have aligned on the Long-Term Support (LTS) strategy. Initially, there were three years between LTS versions, but this is now only two years.

JDK 21, released last September, is now the current LTS release, which many users will choose to deploy in production at some point.

In this webinar, we’ll explore what the new features are since JDK 17 and how they can make developers more productive and code perform better.

Specifically, we’ll look at the full new features:

Record patterns
Pattern matching for switch
Sequenced collections
Virtual threads

We’ll also highlight some of the interesting preview features and incubator modules:

Structured concurrency
Scoped values
Unnamed patterns and variables
The vector API

By the end of the webinar, you’ll be ready to start with JDK 21!
