Change Log
----------

1.0b2
~~~~~

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 It has been replaced by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.


1.0b1
~~~~~

Released on May 17, 2013

* Implementation updated to implement the `HTML specification
  <http://www.whatwg.org/specs/web-apps/current-work/>`_ as of 5th May
  2013 (`SVN <http://svn.whatwg.org/webapps/>`_ 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
    <http://code.google.com/p/html5lib/issues/detail?id=215>`_: Properly
    detect seekable streams;

  * `Google Code 206
    <http://code.google.com/p/html5lib/issues/detail?id=206>`_: add
    support for <video preload=...>, <audio preload=...>;

  * `Google Code 205
    <http://code.google.com/p/html5lib/issues/detail?id=205>`_: add
    support for <video poster=...>;

  * `Google Code 202
    <http://code.google.com/p/html5lib/issues/detail?id=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/.
