What exactly is added in the language levels of Java 7.0 and 8.0?

I just noticed the ability to select the Java language levels 7.0 and 8.0 in IntelliJ (in the "Project Settings" section).

Where can I find a brief description of what they allow? Level 7.0 is declared to enable "Dimonds" (what is this?), Lines in radio buttons (cool!) And "etc ..."?

Level 8.0 has Sample Annotations, which I don’t know about.

Do I need to use the appropriate JDK to install a higher level? IntelliJ does not seem to mind installing the language 7.0 and JDK 1.6.
