Lxml

==================

Features added
--------------

Bugs fixed
----------

* Crash when building an nsmap (Element property) with empty
namespace URIs.

* Crash due to race condition when errors (or user messages) occur
during threaded XSLT processing.

* XSLT stylesheet compilation could ignore compilation errors.

Other changes
--------------

==================

Features added
--------------

* ``lxml.html.tostring()`` gained new serialisation options
``with_tail`` and ``doctype``.

Bugs fixed
----------

* Fixed a crash when using ``iterparse()`` for HTML parsing and
requesting start events.

* Fixed parsing of more selectors in cssselect. Whitespace before
pseudo-elements and pseudo-classes is significant as it is a
descendant combinator.
"E :pseudo" should parse the same as "E \*:pseudo", not "E:pseudo".
Patch by Simon Sapin.

* lxml.html.diff no longer raises an exception when hitting
'img' tags without 'src' attribute.

Other changes
--------------

==================

Features added
--------------

* ``lxml.objectify.deannotate()`` has a new boolean option
``cleanup_namespaces`` to remove the objectify namespace
declarations (and generally clean up the namespace declarations)
after removing the type annotations.

* ``lxml.objectify`` gained its own ``SubElement()`` function as a
copy of ``etree.SubElement`` to avoid an otherwise redundant import
of ``lxml.etree`` on the user side.

Bugs fixed
----------

* Fixed the "descendant" bug in cssselect a second time (after a first
fix in lxml 2.3.1). The previous change resulted in a serious
performance regression for the XPath based evaluation of the
translated expression. Note that this breaks the usage of some of
the generated XPath expressions as XSLT location paths that
previously worked in 2.3.1.

* Fixed parsing of some selectors in cssselect. Whitespace after combinators
">", "+" and "~" is now correctly ignored. Previously it was parsed as
a descendant combinator. For example, "div> .foo" was parsed the same as
"div>* .foo" instead of "div>.foo". Patch by Simon Sapin.

Other changes
--------------

==================

Features added
--------------

* New option ``kill_tags`` in ``lxml.html.clean`` to remove specific
tags and their content (i.e. their whole subtree).

* ``pi.get()`` and ``pi.attrib`` on processing instructions to parse
pseudo-attributes from the text content of processing instructions.

* ``lxml.get_include()`` returns a list of include paths that can be
used to compile external C code against lxml.etree. This is
specifically required for statically linked lxml builds when code
needs to compile against the exact same header file versions as lxml
itself.

* ``Resolver.resolve_file()`` takes an additional option
``close_file`` that configures if the file(-like) object will be
closed after reading or not. By default, the file will be closed,
as the user is not expected to keep a reference to it.

Bugs fixed
----------

* HTML cleaning didn't remove 'data:' links.

* The html5lib parser integration now uses the 'official'
implementation in html5lib itself, which makes it work with newer
releases of the library.

* In ``lxml.sax``, ``endElementNS()`` could incorrectly reject a plain
tag name when the corresponding start event inferred the same plain
tag name to be in the default namespace.

* When an open file-like object is passed into ``parse()`` or
``iterparse()``, the parser will no longer close it after use. This
reverts a change in lxml 2.3 where all files would be closed. It is
the users responsibility to properly close the file(-like) object,
also in error cases.

* Assertion error in lxml.html.cleaner when discarding top-level elements.

* In lxml.cssselect, use the xpath 'A//B' (short for
'A/descendant-or-self::node()/B') instead of 'A/descendant::B' for
the css descendant selector ('A B'). This makes a few edge cases
like ``"div *:last-child"`` consistent with the selector behavior in
WebKit and Firefox, and makes more css expressions valid location
paths (for use in xsl:template match).

* In lxml.html, non-selected ``<option>`` tags no longer show up in the
collected form values.

* Adding/removing ``<option>`` values to/from a multiple select form
field properly selects them and unselects them.

Other changes
--------------

* Static builds can specify the download directory with the
``--download-dir`` option.

================

Features added
--------------

* When looking for children, ``lxml.objectify`` takes '{}tag' as
meaning an empty namespace, as opposed to the parent namespace.

Bugs fixed
----------

* When finished reading from a file-like object, the parser
immediately calls its ``.close()`` method.

* When finished parsing, ``iterparse()`` immediately closes the input
file.

* Work-around for libxml2 bug that can leave the HTML parser in a
non-functional state after parsing a severely broken document (fixed
in libxml2 2.7.8).

* ``marque`` tag in HTML cleanup code is correctly named ``marquee``.

Other changes
--------------

* Some public functions in the Cython-level C-API have more explicit
return types.

=====================

Features added
--------------

Bugs fixed
----------

* Crash in newer libxml2 versions when moving elements between
documents that had attributes on replaced XInclude nodes.

* ``XMLID()`` function was missing the optional ``parser`` and
``base_url`` parameters.

* Searching for wildcard tags in ``iterparse()`` was broken in Py3.

* ``lxml.html.open_in_browser()`` didn't work in Python 3 due to the
use of os.tempnam. It now takes an optional 'encoding' parameter.
