Python-Markdown 2.6 Release Notes

We are pleased to release Python-Markdown 2.6 which adds a few new features and fixes various bugs. See the list of changes below for details.

Python-Markdown version 2.6 supports Python versions 2.7, 3.2, 3.3, and 3.4 as well as PyPy.

Backwards-incompatible Changes

safe_mode Deprecated

Both safe_mode and the associated html_replacement_text keywords are deprecated in version 2.6 and will raise a DeprecationWarning. The safe_mode and html_replacement_text keywords will be ignored in the next release. The so-called "safe mode" was never actually "safe" which has resulted in many people having a false sense of security when using it. As an alternative, the developers of Python-Markdown recommend that any untrusted content be passed through an HTML sanitizer (like [Bleach]) after being converted to HTML by markdown. In fact, [Bleach Whitelist] provides a curated list of tags, attributes, and styles suitable for filtering user-provided HTML using bleach.

If your code previously looked like this:

html = markdown.markdown(text, safe_mode=True)

Then it is recommended that you change your code to read something like this:

import bleach
from bleach_whitelist import markdown_tags, markdown_attrs
html = bleach.clean(markdown.markdown(text), markdown_tags, markdown_attrs)

If you are not interested in sanitizing untrusted text, but simply desire to escape raw HTML, then that can be accomplished through an extension which removes HTML parsing:

from markdown.extensions import Extension
class EscapeHtml(Extension):
def extendMarkdown(self, md, md_globals):
del md.preprocessors['html_block']
del md.inlinePatterns['html']
</tr></table>
