| 5 | % Rules for maintenance: |
| 6 | % |
| 7 | % * Anyone can add text to this document. Do not spend very much time |
| 8 | % on the wording of your changes, because your text will probably |
| 9 | % get rewritten to some degree. |
| 10 | % |
| 11 | % * The maintainer will go through Misc/NEWS periodically and add |
| 12 | % changes; it's therefore more important to add your changes to |
| 13 | % Misc/NEWS than to this file. |
| 14 | % |
| 15 | % * This is not a complete list of every single change; completeness |
| 16 | % is the purpose of Misc/NEWS. Some changes I consider too small |
| 17 | % or esoteric to include. If such a change is added to the text, |
| 18 | % I'll just remove it. (This is another reason you shouldn't spend |
| 19 | % too much time on writing your addition.) |
| 20 | % |
| 21 | % * If you want to draw your new text to the attention of the |
| 22 | % maintainer, add 'XXX' to the beginning of the paragraph or |
| 23 | % section. |
| 24 | % |
| 25 | % * It's OK to just add a fragmentary note about a change. For |
| 26 | % example: "XXX Describe the transmogrify() function added to the |
| 27 | % socket module." The maintainer will research the change and |
| 28 | % write the necessary text. |
| 29 | % |
| 30 | % * You can comment out your additions if you like, but it's not |
| 31 | % necessary (especially when a final release is some months away). |
| 32 | % |
| 33 | % * Credit the author of a patch or bugfix. Just the name is |
| 34 | % sufficient; the e-mail address isn't necessary. |
| 35 | % |
| 36 | % * It's helpful to add the bug/patch number as a comment: |
| 37 | % |
| 38 | % % Patch 12345 |
| 39 | % XXX Describe the transmogrify() function added to the socket |
| 40 | % module. |
| 41 | % (Contributed by P.Y. Developer.) |
| 42 | % |
| 43 | % This saves the maintainer the effort of going through the SVN log |
| 44 | % when researching a change. |

| 53 | \tableofcontents |
| 54 | |
| 55 | This article explains the new features in Python 3.0. No release date |
| 56 | for Python 3.0 has been set; it will probably be released in mid 2008. |
| 57 | |
| 58 | % Compare with previous release in 2 - 3 sentences here. |
| 59 | |
| 60 | This article doesn't attempt to provide a complete specification of |
| 61 | the new features, but instead provides a convenient overview. For |
| 62 | full details, you should refer to the documentation for Python 3.0. |
| 63 | % add hyperlink when the documentation becomes available online. |
| 64 | If you want to understand the complete implementation and design |
| 65 | rationale, refer to the PEP for a particular new feature. |
| 66 | |
| 67 | |
| 68 | %====================================================================== |
| 69 | |
| 70 | % Large, PEP-level features and changes should be described here. |
| 71 | |
| 72 | % Should there be a new section here for 3k migration? |
| 73 | % Or perhaps a more general section describing module changes/deprecation? |
| 74 | % sets module deprecated |
| 75 | |
| 76 | %====================================================================== |
| 77 | \section{Other Language Changes} |
| 78 | |
| 79 | Here are all of the changes that Python 2.6 makes to the core Python |
| 80 | language. |
| 81 | |
| 82 | \begin{itemize} |
| 83 | |
| 84 | \item Detailed changes are listed here. |
| 85 | |
| 86 | \end{itemize} |

| 90 | \subsection{Optimizations} |
| 91 | |
| 92 | \begin{itemize} |
| 93 | |
| 94 | \item Detailed changes are listed here. |
| 95 | |
| 96 | \end{itemize} |
| 97 | |
| 98 | The net result of the 3.0 optimizations is that Python 3.0 runs the |
| 99 | pystone benchmark around XX\% slower than Python 2.6. |
| 100 | |
| 101 | |
| 102 | %====================================================================== |
| 103 | \section{New, Improved, and Deprecated Modules} |
| 104 | |
| 105 | As usual, Python's standard library received a number of enhancements and |
| 106 | bug fixes. Here's a partial list of the most notable changes, sorted |
| 107 | alphabetically by module name. Consult the |
| 108 | \file{Misc/NEWS} file in the source tree for a more |
| 109 | complete list of changes, or look through the CVS logs for all the |
| 110 | details. |
| 111 | |
| 112 | \begin{itemize} |
| 113 | |
| 114 | \item Detailed changes are listed here. |
| 115 | |
| 116 | \end{itemize} |
| 117 | |
| 118 | |
| 119 | %====================================================================== |
| 120 | % whole new modules get described in \subsections here |

| 124 | \section{Build and C API Changes} |
| 125 | |
| 126 | Changes to Python's build process and to the C API include: |
| 127 | |
| 128 | \begin{itemize} |
| 129 | |
| 130 | \item Detailed changes are listed here. |
| 131 | |
| 132 | \end{itemize} |

| 140 | |
| 141 | %====================================================================== |
| 142 | \section{Other Changes and Fixes \label{section-other}} |
| 143 | |
| 144 | As usual, there were a bunch of other improvements and bugfixes |
| 145 | scattered throughout the source tree. A search through the change |
| 146 | logs finds there were XXX patches applied and YYY bugs fixed between |
| 147 | Python 2.6 and 3.0. Both figures are likely to be underestimates. |
| 148 | |
| 149 | Some of the more notable changes are: |
| 150 | |
| 151 | \begin{itemize} |
| 152 | |
| 153 | \item Details go here. |

| 162 | changes to your code: |
