the xml package, and i18n support through the gettext module); a list
of all new modules is included below. Lots of bugs have been fixed.
The process for making major new changes to the language has changed
since Python 1.6. Enhancements must now be documented by a Python
Enhancement Proposal (PEP) before they can be accepted.
There are several important syntax enhancements, described in more

Python Enhancement Proposal (PEP)
---------------------------------
PEP stands for Python Enhancement Proposal. A PEP is a design
document providing information to the Python community, or describing
a new feature for Python. The PEP should provide a concise technical
specification of the feature and a rationale for the feature.
We intend PEPs to be the primary mechanisms for proposing new
features, for collecting community input on an issue, and for
documenting the design decisions that have gone into Python. The PEP
author is responsible for building consensus within the community and
documenting dissenting opinions.
The PEPs are available at http://python.sourceforge.net/peps/.
