2.2.6 (2010-03-02)
==================
Bugs fixed
----------
* Fixed several Python 3 regressions by building with Cython 0.11.3.
2.2.5 (2010-02-28)
==================
Features added
--------------
* Support for running XSLT extension elements on the input root node
(e.g. in a template matching on "/").
Bugs fixed
----------
* Crash in XPath evaluation when reading smart strings from a document
other than the original context document.
* Support recent versions of html5lib by not requiring its
``XHTMLParser`` in ``htmlparser.py`` anymore.
* Manually instantiating the custom element classes in
``lxml.objectify`` could crash.
* Invalid XML text characters were not rejected by the API when they
appeared in unicode strings directly after non-ASCII characters.
* lxml.html.open_http_urllib() did not work in Python 3.
* The functions ``strip_tags()`` and ``strip_elements()`` in
``lxml.etree`` did not remove all occurrences of a tag in all cases.
* Crash in XSLT extension elements when the XSLT context node is not
an element.
* The resolve_entities option did not work in the incremental feed
parser.
* Looking up and deleting attributes without a namespace could hit a
namespaced attribute of the same name instead.
* Late errors during calls to SubElement() (e.g. attribute related
ones) could leave a partially initialised element in the tree.
* Modifying trees that contain parsed entity references could result
in an infinite loop.
* ObjectifiedElement.__setattr__ created an empty-string child
element when the attribute value was rejected as a non-unicode/
non-ascii string
* Syntax errors in lxml.cssselect could result in misleading error
messages.
* Invalid syntax in CSS expressions could lead to an infinite loop
in the parser of lxml.cssselect.
* CSS special character escapes were not properly handled in
lxml.cssselect.
* CSS Unicode escapes were not properly decoded in lxml.cssselect.
* Select options in HTML forms that had no explicit value attribute
were not handled correctly. The HTML standard dictates that their
value is defined by their text content. This is now supported by
lxml.html.
* XPath raised a TypeError when finding CDATA sections. This is now
fully supported.
* Calling help(lxml.objectify) didn't work at the prompt.
* The ElementMaker in lxml.objectify no longer defines the default
namespaces when annotation is disabled.
* Feed parser failed to honout the 'recover' option on parse errors.
* Diverting the error logging to Python's logging system was broken.
Require setuptools-0.6c11 as it fails at least with newer Python 2.6
otherwise.
2.2.2 (2009-06-21)
==================
Features added
--------------
* New helper functions ``strip_attributes()``, ``strip_elements()``,
``strip_tags()`` in lxml.etree to remove attributes/subtrees/tags
from a subtree.
Bugs fixed
----------
* Namespace cleanup on subtree insertions could result in missing
namespace declarations (and potentially crashes) if the element
defining a namespace was deleted and the namespace was not used by
the top element of the inserted subtree but only in deeper subtrees.
* Raising an exception from a parser target callback didn't always
terminate the parser.
* Only {true, false, 1, 0} are accepted as the lexical representation for
BoolElement ({True, False, T, F, t, f} not any more), restoring lxml <= 2.0
behaviour.
2.2.1 (2009-06-02)
==================
Features added
--------------
* Injecting default attributes into a document during XML Schema
validation (also at parse time).
* Pass ``huge_tree`` parser option to disable parser security
restrictions imposed by libxml2 2.7.
Bugs fixed
----------
* The script for statically building libxml2 and libxslt didn't work
in Py3.
* ``XMLSchema()`` also passes invalid schema documents on to libxml2
for parsing (which could lead to a crash before release 2.6.24).
2.2 (2009-03-21)
================
Features added
--------------
* Support for ``standalone`` flag in XML declaration through
``tree.docinfo.standalone`` and by passing ``standalone=True/False``
on serialisation.
Bugs fixed
----------
* Crash when parsing an XML Schema with external imports from a
filename.
2.2beta4 (2009-02-27)
=====================
Features added
--------------
* Support strings and instantiable Element classes as child arguments
to the constructor of custom Element classes.
* GZip compression support for serialisation to files and file-like
objects.
Bugs fixed
----------
* Deep-copying an ElementTree copied neither its sibling PIs and
comments nor its internal/external DTD subsets.
* Soupparser failed on broken attributes without values.
* Crash in XSLT when overwriting an already defined attribute using
``xsl:attribute``.
* Crash bug in exception handling code under Python 3. This was due
to a problem in Cython, not lxml itself.
* ``lxml.html.FormElement._name()`` failed for non top-level forms.
* ``TAG`` special attribute in constructor of custom Element classes
was evaluated incorrectly.
Other changes
-------------
* Official support for Python 3.0.1.
* ``Element.findtext()`` now returns an empty string instead of None
for Elements without text content.
2.2beta3 (2009-02-17)
=====================
Features added
--------------
* ``XSLT.strparam()`` class method to wrap quoted string parameters
that require escaping.
Bugs fixed
----------
* Memory leak in XPath evaluators.
* Crash when parsing indented XML in one thread and merging it with
other documents parsed in another thread.
* Setting the ``base`` attribute in ``lxml.objectify`` from a unicode
string failed.
* Fixes following changes in Python 3.0.1.
* Minor fixes for Python 3.
Other changes
-------------
* The global error log (which is copied into the exception log) is now
local to a thread, which fixes some race conditions.
* More robust error handling on serialisation.
2.2beta2 (2009-01-25)
=====================
Bugs fixed
----------
* Potential memory leak on exception handling. This was due to a
problem in Cython, not lxml itself.
* ``iter_links`` (and related link-rewriting functions) in
``lxml.html`` would interpret CSS like ``url("link")`` incorrectly
(treating the quotation marks as part of the link).
* Failing import on systems that have an ``io`` module.
2.1.5 (2009-01-06)
==================
Bugs fixed
----------
* Potential memory leak on exception handling. This was due to a
problem in Cython, not lxml itself.
* Failing import on systems that have an ``io`` module.
2.2beta1 (2008-12-12)
=====================
Features added
--------------
* Allow ``lxml.html.diff.htmldiff`` to accept Element objects, not
just HTML strings.
Bugs fixed
----------
* Crash when using an XPath evaluator in multiple threads.
* Fixed missing whitespace before ``Link:...`` in ``lxml.html.diff``.
Other changes
-------------
* Export ``lxml.html.parse``.
2.1.4 (2008-12-12)
==================
Bugs fixed
----------
* Crash when using an XPath evaluator in multiple threads.
2.0.11 (2008-12-12)
===================
Bugs fixed
----------
* Crash when using an XPath evaluator in multiple threads.
2.2alpha1 (2008-11-23)
======================
Features added
--------------
* Support for XSLT result tree fragments in XPath/XSLT extension
functions.
* QName objects have new properties ``namespace`` and ``localname``.
* New options for exclusive C14N and C14N without comments.
* Instantiating a custom Element classes creates a new Element.
Bugs fixed
----------
* XSLT didn't inherit the parse options of the input document.
* 0-bytes could slip through the API when used inside of Unicode
strings.
* With ``lxml.html.clean.autolink``, links with balanced parenthesis,
that end in a parenthesis, will be linked in their entirety (typical
with Wikipedia links).
lxml is a Pythonic binding for the libxml2 and libxslt libraries.
It is unique in that it combines the speed and feature completeness
of these libraries with the simplicity of a native Python API,
mostly compatible but superior to the well-known ElementTree API.
