We have rewritten significant portions of the code, dramatically +extending the extension API, increased performance, and added numerous +extensions to the distribution (including an extension that mimics PHP Markdown +Extra), all while maintaining backward compatibility with the end user API in +version 1.7. + +Python-Markdown supports Python versions 2.3, 2.4, 2.5, and 2.6. We've even +released a version converted to Python 3.0! + +Backwards-incompatible Changes +------------------------------ + +While Python-Markdown has experienced numerous internal changes, those changes +should only affect extension authors. If you have not written your own +extensions, then you should not need to make any changes to your code. +However, you may want to ensure that any third party extensions you are using +are compatible with the new API. + +The new extension API is fully documented in [[writing_extensions]]. Below is a +summary of the significant changes: + +* The old home-grown NanoDOM has been replaced with ElementTree. Therefore all + extensions must use ElementTree rather than the old NanoDOM. +* The various processors and patterns are now stored with OrderedDicts rather + than lists. Any code adding processors and/or patterns into Python-Markdown + will need to be adjusted to use the new API using OrderedDicts. +* The various types of processors available have been either combined, added, + or removed. Ensure that your processors match the currently supported types. + +What's New in Python-Markdown 2.0 +--------------------------------- + +Thanks to the work of Artem Yunusov as part of GSoC 2008, Python-Markdown uses +ElementTree internally to build the (X)HTML document from markdown source text. +This has resolved various issues with the older home-grown NanoDOM and made +notable increases in performance. + +Artem also refactored the Inline Patterns to better support nested patterns +which has resolved many inconsistencies in Python-Markdown's parsing of the +markdown syntax. + +The core parser had been completely rewritten, increasing performance and, for +the first time, making it possible to override/add/change the way block level +content is parsed. + +Python-Markdown now parses markdown source text more closely to the other +popular implementations (Perl, PHP, etc.) than it ever has before. With the +exception of a few minor insignificant differences, any difference should be +considered a bug, rather than a limitation of the parser. + +The option to return HTML4 output as apposed to XHTML has been added. In +addition, extensions should be able to easily add additional output formats. + +As part of implementing markdown in the Dr. Project project (a Trac fork), among +other things, David Wolever refactored the "extension" keyword so that it +accepts either the extension names as strings or instances of extensions. This +makes it possible to include multiple extensions in a single module. + +Numerous extensions are included in the distribution by default. See +[[available_extensions]] for a complete list. + +See the [[change_log]] for a full list of changes. + -- cgit v1.2.3
