There is an article on Python NetWorkSpaces in the August issue of Dr. Dobb's. See the article at http://www.ddj.com/dept/lightlang/200001971
Probably the most interesting new feature in this release is the new imap and starmap methods in the Sleigh class. These are very much like the corresponding itertools functions, making it very easy for Python programmers to quickly understand. It also enables a huge number of tasks to be submitted to the system without using a huge amount of memory, and allowing the results to be processed as they arrive.
This release includes a variety of enhancements. See the ChangeLog for more details.
Version 1.4.3 of the NetWorkSpaces server and Python client have been released. This is the first new release on source forge in a long time. There have been many improvements, including iterated operations, improved web interface, usability enhancements and bug fixes.
