This article explains the new features in Python 2.4, released in December
2004.
Python 2.4 is a medium-sized release. It doesn't introduce as many
changes as the radical Python 2.2, but introduces more features than
the conservative 2.3 release. The most significant new language
features are function decorators and generator expressions; most other
changes are to the standard library.
According to the CVS change logs, there were 481 patches applied and
502 bugs fixed between Python 2.3 and 2.4. Both figures are likely to
be underestimates.
This article doesn't attempt to provide a complete specification of
every single new feature, but instead provides a brief introduction to
each feature. For full details, you should refer to the documentation
for Python 2.4, such as the Python Library
Reference and the Python Reference
Manual. Often you will be referred to the PEP for a particular new
feature for explanations of the implementation and design rationale.
