Aca les dejo parte del post original de Oracle, sobre el nuevo release del JDK:
Java 7 (codename
Dolphin[48]) is an upcoming major update to Java, releasing on July 28, 2011(07.28.2011).
[49] The development period is organized into thirteen milestones; on February 18, 2011, milestone 13, the last milestone was reached.
[50][51] Multiple builds, which generally include enhancements and bug fixes, are released per milestone. The
Feature list at the Open JDK 7 project lists many of the expected feature changes.
The expected feature additions for Java 7
[52]
- Strings in switch[56]
- Automatic resource management[57]
- Improved Type Inference for Generic Instance Creation[58]
- Simplified Varargs Method Invocation[59]
- Better integral literals allowing for underscores as digit separators
- Concurrency utilities under JSR 166[60]
- New file I/O library to enhance platform independence and add support for metadata and symbolic links. The new packages are java.nio.file and java.nio.file.attribute[61][62]
- Library-level support for Elliptic curve cryptography algorithms
- An XRender pipeline for Java 2D, which improves handling of features specific to modern GPUs
- New platform APIs for the graphics features originally planned for release in Java version 6u10
- Enhanced library-level support for new network protocols, including SCTP and Sockets Direct Protocol

Lambda, Jigsaw, and part of Coin were dropped from Java 7. Java 8 will be implemented with the remaining features in late 2012.
