Java SE 7 (July 28, 2011)

Java 7 (codename Dolphin) is a major update to Java which was launched on July 7 of 2011 and was made available on July 28, 2011. The development period was organized into thirteen milestones; on February 18, 2011, milestone 13, the last milestone was reached. On average, 8 builds (which generally included enhancements and bug fixes) were released per milestone. The Feature list at the Open JDK 7 project lists many of the feature changes.
The feature additions for Java 7

JVM support for dynamic languages, following the prototyping work currently done on the Multi Language Virtual Machine
Compressed 64-bit pointersAvailable in Java 6 with -XX:+UseCompressedOops
Small language changes (grouped under a project named Coin):

Strings in switch
Automatic resource management in try-statement
Improved type inference for generic instance creation
Simplified varargs method invocation
Binary integer literals
Allowing underscores in numeric literals
Catching multiple exception types and rethrowing exceptions with improved type checking

Concurrency utilities under JSR 166
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
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
Upstream updates to XML and Unicode

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