Oracle has released Java 7 today. This is a big release, but not so much for Java: it’s more about the JVM itself. The biggest change that everyone will love is the addition of InvokeDynamic, which will help dynamic languages built on top of the JVM (like JRuby) immensely.
There are some other new features as well, though it’s disappointing to me that JSR335 (also known as ‘zomg lambdas!’) got pushed back to Java 8. Oh well, that ship sailed long ago, but if you haven’t paid attention to the state of Java in a while, you might have heard that this was going to be in Java 7.
You can check out the press release for Java SE 7 on Oracle’s website.
