The documentation has been updated to include the new features found in Python 2.2, including documentation for new modules, and language (syntax) features. Additionally, much of the documentation for features and APIs in previous versions has been clarified and improved.
This release adds major updates from the Python 2.0 documentation,
including documentation for new modules introduced in Python 2.1,
substantially improved coverage of the XML facilities available in
Python, and descriptions of upcoming language and runtime features
(such as full lexical scoping and weak references).
