Released on December 23, 2013

• Fix #127: add work-around for CPython issue #20007: .read(0) on http.client.HTTPResponse drops the rest of the content.
• Fix #115: lxml treewalker can now deal with fragments containing, at their root level, text nodes with non-ASCII characters on Python 2.

Released on September 10, 2013

• No library changes from 1.0b3; released as 0.99 as pip has changed behaviour from 1.4 to avoid installing pre-release versions per PEP 440.

Released on July 24, 2013

• Removed RecursiveTreeWalker from treewalkers._base. Any implementation using it should be moved to NonRecursiveTreeWalker, as everything bundled with html5lib has for years.
• Fix #67 so that BufferedStream to correctly returns a bytes object, thereby fixing any case where html5lib is passed a non-seekable RawIOBase-like object.

Released on June 27, 2013

• Removed reordering of attributes within the serializer. There is now an alphabetical_attributes option which preserves the previous behaviour through a new filter. This allows attribute order to be preserved through html5lib if the tree builder preserves order.
• Removed dom2sax from DOM treebuilders. It has been replaced by treeadapters.sax.to_sax which is generic and supports any treewalker; it also resolves all known bugs with dom2sax.
• Fix treewalker assertions on hitting bytes strings on Python 2. Previous to 1.0b1, treewalkers coped with mixed bytes/unicode data on Python 2; this reintroduces this prior behaviour on Python 2. Behaviour is unchanged on Python 3.

Released on May 17, 2013

• Implementation updated to implement the HTML specification as of 5th May 2013 (SVN revision r7867).
• Python 3.2+ supported in a single codebase using the six library.
• Removed support for Python 2.5 and older.
• Removed the deprecated Beautiful Soup 3 treebuilder. beautifulsoup4 can use html5lib as a parser instead. Note that since it doesn't support namespaces, foreign content like SVG and MathML is parsed incorrectly.
• Removed simpletree from the package. The default tree builder is now etree (using the xml.etree.cElementTree implementation if available, and xml.etree.ElementTree otherwise).
• Removed the XHTMLSerializer as it never actually guaranteed its output was well-formed XML, and hence provided little of use.
• Removed default DOM treebuilder, so html5lib.treebuilders.dom is no longer supported. html5lib.treebuilders.getTreeBuilder("dom") will return the default DOM treebuilder, which uses xml.dom.minidom.
• Optional heuristic character encoding detection now based on charade for Python 2.6 - 3.3 compatibility.
• Optional Genshi treewalker support fixed.
• Many bugfixes, including:
  • #33: null in attribute value breaks XML AttValue;
  • #4: nested, indirect descendant, <button> causes infinite loop;
  • Google Code 215: Properly detect seekable streams;
  • Google Code 206: add support for <video preload=...>, <audio preload=...>;
  • Google Code 205: add support for <video poster=...>;
  • Google Code 202: Unicode file breaks InputStream.
• Source code is now mostly PEP 8 compliant.
• Test harness has been improved and now depends on nose.
• Documentation updated and moved to http://html5lib.readthedocs.org/.
