Changelog

4.9.4

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

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

* LP2046398: Inserting/replacing an ancestor into a node's children could loop indefinitely.

* LP1980767, GH379: ``TreeBuilder.close()`` could fail with a ``TypeError`` after
parsing incorrect input.  Original patch by Enrico Minack.

* LP1522052: A file-system specific test is now optional and should no longer fail
on systems that don't support it.

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

* Wheels include zlib 1.3, libxml2 2.10.3 and libxslt 1.1.39
(zlib 1.2.12, libxml2 2.10.3 and libxslt 1.1.37 on Windows).

* Built with Cython 0.29.37.

4.9.3

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

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.

4.9.2

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

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.
https://gitlab.gnome.org/GNOME/libxml2/-/issues/378

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.

4.9.1

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

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.

4.9.0

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

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.

4.8.0

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

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.

4.7.1

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

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).

4.7.0

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

* Release retracted due to missing files in lxml/includes/.

4.6.5

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

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

* A vulnerability (GHSL-2021-1038) in the HTML cleaner allowed sneaking script
content through SVG images (CVE-2021-43818).

* A vulnerability (GHSL-2021-1037) in the HTML cleaner allowed sneaking script
content through CSS imports and other crafted constructs (CVE-2021-43818).

4.6.4

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

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

* GH317: A new property ``system_url`` was added to DTD entities.
Patch by Thirdegree.

* GH314: The ``STATIC_*`` variables in ``setup.py`` can now be passed via env vars.
Patch by Isaac Jurado.

4.6.3

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

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

* A vulnerability (CVE-2021-28957) was discovered in the HTML Cleaner by Kevin Chung,
which allowed JavaScript to pass through.  The cleaner now removes the HTML5
``formaction`` attribute.

4.6.2

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

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

* A vulnerability (CVE-2020-27783) was discovered in the HTML Cleaner by Yaniv Nizry,
which allowed JavaScript to pass through.  The cleaner now removes more sneaky
"style" content.

4.6.1

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

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

* A vulnerability was discovered in the HTML Cleaner by Yaniv Nizry, which allowed
JavaScript to pass through.  The cleaner now removes more sneaky "style" content.

4.6.0

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

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

* GH310: ``lxml.html.InputGetter`` supports ``__len__()`` to count the number of input fields.
Patch by Aidan Woolley.

* ``lxml.html.InputGetter`` has a new ``.items()`` method to ease processing all input fields.

* ``lxml.html.InputGetter.keys()`` now returns the field names in document order.

* GH-309: The API documentation is now generated using ``sphinx-apidoc``.
Patch by Chris Mayo.

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

* LP1869455: C14N 2.0 serialisation failed for unprefixed attributes
when a default namespace was defined.

* ``TreeBuilder.close()`` raised ``AssertionError`` in some error cases where it
should have raised ``XMLSyntaxError``.  It now raises a combined exception to
keep up backwards compatibility, while switching to ``XMLSyntaxError`` as an
interface.

4.5.2

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

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

* ``Cleaner()`` now validates that only known configuration options can be set.

* LP1882606: ``Cleaner.clean_html()`` discarded comments and PIs regardless of the
corresponding configuration option, if ``remove_unknown_tags`` was set.

* LP1880251: Instead of globally overwriting the document loader in libxml2, lxml now
sets it per parser run, which improves the interoperability with other users of libxml2
such as libxmlsec.

* LP1881960: Fix build in CPython 3.10 by using Cython 0.29.21.

* The setup options "--with-xml2-config" and "--with-xslt-config" were accidentally renamed
to "--xml2-config" and "--xslt-config" in 4.5.1 and are now available again.

4.5.1

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

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

* LP1570388: Fix failures when serialising documents larger than 2GB in some cases.

* LP1865141, GH298: ``QName`` values were not accepted by the ``el.iter()`` method.
Patch by xmo-odoo.

* LP1863413, GH297: The build failed to detect libraries on Linux that are only
configured via pkg-config.
Patch by Hugh McMaster.

4.5.0

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

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

* A new function ``indent()`` was added to insert tail whitespace for pretty-printing
an XML tree.

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

* LP1857794: Tail text of nodes that get removed from a document using item
deletion disappeared silently instead of sticking with the node that was removed.

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

* MacOS builds are 64-bit-only by default.
Set CFLAGS and LDFLAGS explicitly to override it.

* Linux/MacOS Binary wheels now use libxml2 2.9.10 and libxslt 1.1.34.

* LP1840234: The package version number is now available as ``lxml.__version__``.

4.4.3

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

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

* LP1844674: ``itertext()`` was missing tail text of comments and PIs since 4.4.0.

4.4.2

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

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

* LP1835708: ``ElementInclude`` incorrectly rejected repeated non-recursive
includes as recursive.
Patch by Rainer Hausdorf.

4.4.1

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

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

* LP1838252: The order of an OrderedDict was lost in 4.4.0 when passing it as
