Java 21 is released. Check out my new book From Java 17 to 21 to upgrade to Java 21.

Java 17 is a LTS version of Java. Java 17 should be the next version to upgrade if you are using Java 8 or Java 11. It is expected that users of Java 8 and 11 will gradually migrate to Java 17. Spring 6 is released with requirement of JDK 17+. You must upgrade to Java 17 to use Spring 6.

This book covers major changes from Java 11 to Java 17, including Java 12, 13, 14, 15, 16 and 17. Below is a list of these features:

Records
Sealed classes
Switch expressions
Pattern matching
Text blocks
JFR event streaming, JVM constants API, hidden classes
Changes to Java standard libraries
New garbage collectors
Changes to JVM
Packaging tool - jpackage
Foreign function & memory API
Other changes

If you are using Java 11 and planning to upgrade to Java 17, this book can provide you with a valuable reference.
