Due to arrive in June 2010, Python 2.7 has now reached its first beta. Python 2.7 is planned to be the last major edition of the Python 2.x series before it goes into "bug fix mode".

"The 3.0 version of Python (also known as Python3k and Python3000) just got released few hours ago. It's the first ever intentionally backwards-incompatible Python release."

The Python developers have released two new version of the programming language. Versions 2.6.5 and 3.1.2 are both new maintenance releases

Python 3.0a2 Release: December 7th, 2007
http://www.python.org/download/releases/3.0/

Just one week shy of Christmas 2008, the Python world saw the release of version 3 of Python. Big deal, eh? Well ... it turns out it was and is, as Python 3 is the first major release of Python designed from the get-go to be incompatible with prior versions of the language.

Python 2.7 (powerful dynamic programming language that is used in a wide variety of application domains) is scheduled to be the last major version in the 2.x series before it moves into an extended maintenance period.

Developers will be introduced to Spring Python and will learn to develop powerful applications after applying concepts of Spring to the environment of Python. Readers will shown how to use the IoC or Dependency Injection container for Python. Using Jython, developers will be able to link Python and Java components together efficiently as well as learn to add security to their Python application.

This week Python 3.0 was released, and it represents one of those rare instances: Python 3.0 was designed to clear up a lot of now-inertial legacy issues with the Python language and figure out good ways to do things now instead of unquestioningly sticking with what seemed like good ways (or, more often, the least painful ways) to do things five or ten years ago.
