I just finished a little side project of mine, where you can easily see what Java version (>= 5.0) has added which package, class or member: https://robtimus.github.io/whats-new-in-java/.

I started it because too often I didn't really have a full overview of what new features were added. With the more frequent Java release cycle this would become even worse. This little one-pager now solves that issue. It's generated from the latest API, so when Java 11 comes out it will be easily updated.

It has already proved its value to me, because I didn't know that:
* Java 10 has added Collectors for unmodifiable collections and maps.
* Java 9 has finally added StringBuilder support to java.util.regex.Matcher.
* Java 9 has added pipeline support to ProcessBuilder.

Wait what? I just found out that Closeable was only added to the language in Java 5. If you had asked me, I would have sworn it was part of Java from the start.

And apparently in Java 9 they added a method to flag busy waits -___-;

That just proves how some new features just aren't advertised as broadly as others.

Very helpful tool Rob. Now I can see at first glance what's new in the different versions of Java without having to dig much into documentation. I wish I could give you a cow...

No problem, I got enough praise already

BTW, if you watch the repository (https://github.com/robtimus/whats-new-in-java/) you will be informed by GitHub when I'll release a new version (September or October will get one, when Java 11 comes out).
