**Backwards incompatible changes**
- clean: The list of ``ALLOWED_PROTOCOLS`` now defaults to http, https and
mailto. Previously it was a long list of protocols something like ed2k, ftp,
http, https, irc, mailto, news, gopher, nntp, telnet, webcal, xmpp, callto,
feed, urn, aim, rsync, tag, ssh, sftp, rtsp, afs, data.
**Changes**
- clean: Added ``protocols`` to arguments list to let you override the list of
allowed protocols. Thank you, Andreas Malecki!
- linkify: Fix a bug involving periods at the end of an email address. Thank you,
Lorenz Schori!
- linkify: Fix linkification of non-ascii ports. Thank you Alexandre, Macabies!
- linkify: Fix linkify inappropriately removing node tails when dropping nodes.
- Fixed a test that failed periodically.
- Switched from nose to py.test.
- Add test matrix for all supported Python and html5lib versions.
- Limit to html5lib ``>=0.999,!=0.9999,!=0.99999,<0.99999999`` because 0.9999
and 0.99999 are busted.
- Add support for ``python setup.py test``.
Version 1.4
-----------
- Update linkify to use etree type Treeewalker instead of simpletree.
- Updated html5lib to version >= 0.999.
- Update all code to be compatible with Python 3 and 2 using six.
- Switch to Apache License.
Version 1.3
-----------
- Used by Python 3-only fork.
Version 1.2.2
-------------
- Pin html5lib to version 0.95 for now due to major API break.
Version 1.2.1
-------------
- clean() no longer considers "feed:" an acceptable protocol due to
inconsistencies in browser behavior.
Version 1.2
-----------
- linkify() has changed considerably. Many keyword arguments have been
replaced with a single callbacks list. Please see the documentation
for more information.
- Bleach will no longer consider unacceptable protocols when linkifying.
- linkify() now takes a tokenizer argument that allows it to skip
sanitization.
- delinkify() is gone.
- Removed exception handling from _render. clean() and linkify() may now
throw.
- linkify() correctly ignores case for protocols and domain names.
- linkify() correctly handles markup within an <a> tag.
Bleach is an HTML sanitizing library that escapes or strips markup
and attributes based on a white list. Bleach can also linkify text
safely, applying filters that Django's ``urlize`` filter cannot,
and optionally setting ``rel`` attributes, even on links already
in the text.
