Java 8 Developer preview version is out for testing. The key
feature of the release is Project Lambda, which is intended to make it easier
to write code for multiprocessors. There are numerous enhancements to core/libs
and core/lang.
Nashorn JavaScript Engine is also new addition. One can design
and implement a new lightweight, high-performance implementation of JavaScript,
and integrate it into the JDK. The new engine will be made available to Java
applications via the existing javax.script API, and also more generally via a
new command-line tool.
Final version may get released in Q1 2014. One can download
