News Facts

Oracle today announced the availability of Java Platform, Standard Edition 7 (Java SE 7), the first release of the Java platform under Oracle stewardship.
The Java SE 7 release is the result of industry-wide development involving open review, weekly builds and extensive collaboration between Oracle engineers and members of the worldwide Java ecosystem via the OpenJDK Community and the Java Community Process (JCP).
Java SE 7 delivers:
Language changes to help increase developer productivity and simplify common programming tasks by reducing the amount of code needed, clarifying syntax and making code easier to read. (JSR 334: Project Coin)
Improved support for dynamic languages (including: Ruby, Python and JavaScript), resulting in substantial performance increases on the JVM. (JSR 292: InvokeDynamic)
A new multicore-ready API that enables developers to more easily decompose problems into tasks that can then be executed in parallel across arbitrary numbers of processor cores. (JSR 166: Fork/Join Framework)
A comprehensive I/O interface for working with file systems that can access a wider array of file attributes and offer more information when errors occur. (JSR 203: NIO.2)
New networking and security features
Expanded support for internationalization, including Unicode 6.0 support
Updated versions of numerous libraries
Strong backward compatibility of Java SE 7 with previous versions of the platform preserves the skill sets of current Java software developers and protects Java technology investments.
Developers interested in getting started immediately with the Java SE 7 release can leverage the NetBeans Integrated Development Environment (IDE) 7.0, Eclipse Indigo with the additional Java SE 7 plug-in or IntelliJ IDEA 10.5, which support the latest features of the Java SE 7 platform. Oracle JDeveloper support for JDK 7 is intended for a release later this year.

I'm happy primarily because support for InvokeDynamic will make the JVM a much better platform for dynamic languages. The new filesystem APIs and multicore support (fork/join) are also nice.
