There are many useful features introduces from Java 8 to Java 13 like lambda expressions, Stream API, New Date, and Time API, Creating Immutable Lists, var for storing local variables without types, String in switch case, Text Block and many more.
Staying up to speed with Java is difficult for any Java developer, as a new version of Java is released only six months but If you want to learn those new features and looking for some resources then the following courses will help you.
To summarize releases over the last two years since implementing the predictable six-month release cadence:
Java 10: 12 features
Java 11: 17 features
Java 12: 8 features
Java 13: 5 features
Java 14 : 16 features
Btw, If you are a beginner and learning Java, I suggest you join the Java Programming MasterClass course by Tim Buchalaka on [Udemy], one of the best courses to learn Java in depth.
Anyway without wasting any more of your time, here are some of the short courses to learn new features of Java from JDK 8 to JDK 13.
1. What's New in Java 8 By [José Paumard]
This course covers the most useful parts of Java 8. This update of the Java platform is the biggest of all. It's even bigger than Java 5 that saw the introduction of generics. We'll begin with lambda expressions and the Stream API, which bring new fundamental patterns to the Java platform.
Many problems solved with the Iterator pattern are now solved much more efficiently with the patterns brought by the Stream API. But Java 8 is not only about lambdas, streams, and collectors, there is also a new Java Date and Time API which are covered in this course.

2. What's New in Java 9 By [Sander Mak]
Java 9 is packed with new features. In this course, What's New in Java 9, you'll get an overview of the most important changes to the language and libraries. First, you'll delve into the module system, introducing modules into the Java language.
Then, you'll discover jshell, a new tool for interactively experimenting with Java code. Finally, you'll explore smaller and incremental changes, such as improvements to APIs like Stream and Optional, the addition of collection factory methods, and newly introduced APIs such as ProcessHandle and HttpClient.
When you're finished with this course, you'll be ready to make the most of Java 9 in your own projects.

3. What's New in Java 10: Local-variable Type Inference
Java 10 is released only six months after Java 9. In this course, What's New in Java 10: Local-variable Type Inference, you'll learn about the accelerated release schedule of Java and what it means for you.
First, you'll learn about the turning point in the release schedule and the new features that are in store. Next, you'll dive into the most eye-catching feature in Java 10: the introduction of local-variable type inference.
Finally, you'll uncover other new features such as performance improvements to the G1 Garbage Collector, the introduction of Application Class Data Sharing, and improved Docker awareness of JDK 10. When you're finished with this course, you'll be ready to make the most of Java 10 in your own projects.

You can see that all these courses are from [Pluralsight] and you can access them for free in this month. After this, you can access them with just one membership, you don't need to buy individual courses. Btw, if you don't have a Pluralsight membership then this is probably the best time to get one to give your learning a boost.
Is there a single course which covers all features form Java 8 to 13?
For those, who prefer to buy courses than memberships, there is still one course I can suggest which comprises all JDK changes from Java 8 to Java 12, it's Java New Features (Java 12, Java 11, Java 10, Java9 & Java8) course on [Udemy]. It doesn't cover Java 13 but still a great collection to learn other features. You can buy it on under $10 in several of Udemy flash sales which happen every month.
That's all about some of the best courses to keep yourself up-to-date with new Java features introduced from JDK 8 to JDK 13. These courses are small and to-the-point which means you can complete them in a quick time and learn only meaningful and essential features instead of learning everything.
