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.
