| 89 | <P> | |
| 90 | This article explains the new features in Python 2.4, released in December | |
| 91 | 2004. | |
| 92 | ||
| 93 | <P> | |
| 94 | Python 2.4 is a medium-sized release. It doesn't introduce as many | |
| 95 | changes as the radical Python 2.2, but introduces more features than | |
| 96 | the conservative 2.3 release. The most significant new language | |
| 97 | features are function decorators and generator expressions; most other | |
| 98 | changes are to the standard library. | |
| 99 | ||
| 100 | <P> | |
| 101 | According to the CVS change logs, there were 481 patches applied and | |
| 102 | 502 bugs fixed between Python 2.3 and 2.4. Both figures are likely to | |
| 103 | be underestimates. | |
| 104 | ||
| 105 | <P> | |
| 106 | This article doesn't attempt to provide a complete specification of | |
| 107 | every single new feature, but instead provides a brief introduction to | |
| 108 | each feature. For full details, you should refer to the documentation | |
| 109 | for Python 2.4, such as the <em class="citetitle"><a | |
| 110 | href="../lib/lib.html" | |
| 111 | title="Python Library | |
| 112 | Reference" | |
| 113 | >Python Library | |
| 114 | Reference</a></em> and the <em class="citetitle"><a | |
| 115 | href="../ref/ref.html" | |
| 116 | title="Python Reference | |
| 117 | Manual" | |
| 118 | >Python Reference | |
| 119 | Manual</a></em>. Often you will be referred to the PEP for a particular new | |
| 120 | feature for explanations of the implementation and design rationale. | |
