All, I'm looking for some very high-level resources as to how Java has changed since 2006, the last time I worked with the language.

I'm specifically curious as to new language features and how the language may have evolved similarly or differently to C# as I'm a .NET developer.

I realize the question is vague and open-ended, but hopefully someone can point me in a right direction or give me a pie in the sky summary. Just looking for awareness, not implementation details.
