Lxml

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

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

* LP2008911: ``lxml.objectify`` accepted non-decimal numbers like ``²²²`` as integers.

* A memory leak in ``lxml.html.clean`` was resolved by switching to Cython 0.29.34+.

* GH348: URL checking in the HTML cleaner was improved.
Patch by Tim McCormack.

* GH371, GH373: Some regex strings were changed to raw strings to fix Python warnings.
Patches by Jakub Wilk and Anthony Sottile.

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

* Wheels include zlib 1.2.13, libxml2 2.10.3 and libxslt 1.1.38
(zlib 1.2.12, libxml2 2.10.3 and libxslt 1.1.37 on Windows).

* Built with Cython 0.29.36 to adapt to changes in Python 3.12.

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

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

* CVE-2022-2309: A Bug in libxml2 2.9.1[0-4] could let namespace declarations
from a failed parser run leak into later parser runs. This bug was worked around
in lxml and resolved in libxml2 2.10.0.

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

* LP1981760: ``Element.attrib`` now registers as ``collections.abc.MutableMapping``.

* lxml now has a static build setup for macOS on ARM64 machines (not used for building wheels).
Patch by Quentin Leffray.

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

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

* A crash was resolved when using ``iterwalk()`` (or ``canonicalize()``)
after parsing certain incorrect input. Note that ``iterwalk()`` can crash
on *valid* input parsed with the same parser *after* failing to parse the
incorrect input.

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

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

* GH341: The mixin inheritance order in ``lxml.html`` was corrected.
Patch by xmo-odoo.

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

* Built with Cython 0.29.30 to adapt to changes in Python 3.11 and 3.12.

* Wheels include zlib 1.2.12, libxml2 2.9.14 and libxslt 1.1.35
(libxml2 2.9.12+ and libxslt 1.1.34 on Windows).

* GH343: Windows-AArch64 build support in Visual Studio.
Patch by Steve Dower.

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

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

* GH337: Path-like objects are now supported throughout the API instead of just strings.
Patch by Henning Janssen.

* The ``ElementMaker`` now supports ``QName`` values as tags, which always override
the default namespace of the factory.

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

* GH338: In lxml.objectify, the XSI float annotation "nan" and "inf" were spelled in
lower case, whereas XML Schema datatypes define them as "NaN" and "INF" respectively.
Patch by Tobias Deiminger.

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

* Built with Cython 0.29.28.

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

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

* Chunked Unicode string parsing via ``parser.feed()`` now encodes the input data
to the native UTF-8 encoding directly, instead of going through ``Py_UNICODE`` /
``wchar_t`` encoding first, which previously required duplicate recoding in most cases.

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

* The standard namespace prefixes were mishandled during "C14N2" serialisation on Python 3.
See https://mail.python.org/archives/list/lxmlpython.org/thread/6ZFBHFOVHOS5GFDOAMPCT6HM5HZPWQ4Q/

* ``lxml.objectify`` previously accepted non-XML numbers with underscores (like "1_000")
as integers or float values in Python 3.6 and later. It now adheres to the number
format of the XML spec again.

* LP1939031: Static wheels of lxml now contain the header files of zlib and libiconv
(in addition to the already provided headers of libxml2/libxslt/libexslt).

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

* Wheels include libxml2 2.9.12+ and libxslt 1.1.34 (also on Windows).
