The Mercurial version control system reached its 1.6 release this month, and is available for download here.  The DVCS sports two major new features in 1.6.  They include pushable bookmarks and a powerful new revision query language.  The bookmarks may now be synchronized between repositories using push and pull.  1.6 also provides more friendly handling of new and closed named branches, as well as pre and post hooks with parsed command line arguments.

It's official!  Facebook has the world's largest Hadoop cluster.  Facebook's Datawarehouse Hadoop cluster became the largest in May with a system that has more than 21 petabytes of storage in a single HDFS cluster, with 2000 machines.  As Facebook releases more information about its Hadoop cluster, it should help advance the data analytics field as well.

  • Set literals
  • Set and dictionary comprehensions
  • Dictionary views

"It is the last version that will have new features for a while."

Given the availability and progress of Python 3.x, not strictly true. You'll just need to convert your code to get the new features. (Reminiscent of how a big chunk of the Perl 6 improvements have enhanced Perl 5.)
