This may make attribute iteration + slightly slower for long sequences of attributes but allows for attribute manipulation + between iteration steps, giving similar iteration+manipulation semantics as Python lists. + +* Several issues (race conditions, memory leaks on error handling, crashes) + were found via an automated review and subsequently resolved. + Review contributed by devdanzin. + + +7.0.0a2 (2026-06-09) +==================== + +Features added +-------------- + +* GH#511: The ElementPath implementation (``.find()`` etc) was rewritten based on + native traversal of the libxml2 tree instead of passing through Element proxy + objects. This makes some path operations like child steps or predicate evaluation + several times faster. Indexing can be more than 100x faster. + + Note that some operations are also slower due to the new lock usages in lxml 7.0. + Usually, the more selective the path, the faster it runs. + + Original idea and implementation by mahomaho. + + +7.0.0a1 (2026-05-29) +==================== + +Features added +-------------- + +* GH#477, LP#2111289: Experimental support for freethreading Python is enabled + in Python 3.14t and later. + +* GH#466: The shared parser name dict is now local to a parser (as opposed to global), + which allows to control its lifetime and cross-document usage more easily. + It is now also unbounded in size if the ``huge_tree=True`` option is provided. + +* The default chunk size for reading from file-likes in ``iterparse()`` was increased + from 32 KiB to 64 KiB and is now configurable with a new ``chunk_size`` argument. + +* Writing to Python file objects minimises data copying by passing buffers around. + +* GH#502: Predicate evaluation in ``ElementPath`` (``.find*()``) is faster. + +* HTML diffing is faster, following optimisations in CPython 3.15. + +* If multiple Python exceptions get raised from within an lxml operation, they no longer + overwrite old ones but get stacked in the exception context of the latest exception. + +Bugs fixed +---------- + +* Reading from file-like objects that start with a UTF-32 BOM failed to detect the BOM. + +Other changes +------------- + +* Support for Python 3.8 was removed. Python 3.9 will continue to be supported for + several years due to its usage in LTS Linux distributions. + +* Usage on PyPy can currently crash due to the Freethreading Python changes. + This is expected to get fixed in the further releases towards 7.0 final. + +* Some internal adaptations were made for libxml2 2.14.x and 2.15.x. + +* The ``xmlDict...`` C functions of libxml2 are now declared in ``tree.pxd``. + They remain in ``xmlparser.pxd`` for legacy reasons but Cython code that uses them + should migrate the import to ``tree.pxd``. + +* The list of software licenses in LICENSES.txt was clarified and updated + to match the actual set of software being shipped. + +* Built using Cython 3.2.5. + + +6.1.1 (2026-05-18) +================== + +Bugs fixed +---------- + +* The known link attributes in ``lxml.html.defs.link_attrs`` were missing ``xlink:href``, + which can be used for URL bypass attacks in embedded SVG/MathML/etc. content. + https://github.com/fedora-python/lxml_html_clean/security/advisories/GHSA-4jhm-jv67-739f + +* The Linux wheels use a patched libxslt 1.1.43, fixing CVE-2025-7424 and CVE-2025-11731. + +* The Windows wheels use libxslt 1.1.45, fixing CVE-2025-7424 and CVE-2025-11731. + + +6.1.0 (2026-04-17) +================== + +This release fixes a possible external entity injection (XXE) vulnerability in +``iterparse()`` and the ``ETCompatXMLParser``. + +Features added +-------------- + +* GH#486: The HTML ARIA accessibility attributes were added to the set of safe attributes + in ``lxml.html.defs``. This allows ``lxml_html_clean`` to pass them through. + Patch by oomsveta. + +* The default chunk size for reading from file-likes in ``iterparse()`` is now configurable + with a new ``chunk_size`` argument. + +Bugs fixed +---------- + +* LP#2146291: The ``resolve_entities`` option was still set to ``True`` for + ``iterparse`` and ``ETCompatXMLParser``, allowing for external entity injection (XXE) + when using these parsers without setting this option explicitly. + The default was now changed to ``'internal'`` only (as for the normal XML and HTML parsers + since lxml 5.0). + Issue found by Sihao Qiu as CVE-2026-41066. + + +6.0.4 (2026-04-12) +================== + +Bugs fixed +---------- + +* LP#2148019: Spurious MemoryError during namespace cleanup. + + +6.0.3 (2026-04-09) +================== + +Bugs fixed +---------- + +* Several out of memory error cases now raise ``MemoryError`` that were not handled before. + +* Slicing with large step values (outside of ``+/- sys.maxsize``) could trigger undefined C behaviour. + +* LP#2125399: Some failing tests were fixed or disabled in PyPy. + +* LP#2138421: Memory leak in error cases when setting the ``public_id`` or ``system_url`` of a document. + +* Memory leak in case of a memory allocation failure when copying document subtrees. + +* When mapping an XPath result to Python failed, the result memory could leak. + +* When preparing an XSLT transform failed, the XSLT parameter memory could leak. + +Other changes +------------- + +* Built using Cython 3.2.4. + +* Binary wheels use zlib 1.3.2. + + +6.0.2 (2025-09-21) +================== + +Bugs fixed +---------- + +* LP#2125278: Compilation with libxml2 2.15.0 failed. + Original patch by Xi Ruoyao. + +* Setting ``decompress=True`` in the parser had no effect in libxml2 2.15. + +* Binary wheels on Linux and macOS use the library version libxml2 2.14.6. + See https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.14.6 + +* Test failures in libxml2 2.15.0 were fixed. + +Other changes +------------- + +* Binary wheels for Py3.9-3.11 on the ``riscv64`` architecture were added. + +* Error constants were updated to match libxml2 2.15.0. + +* Built using Cython 3.1.4. + + +6.0.1 (2025-08-22) +================== + +Bugs fixed +---------- + +* LP#2116333: ``lxml.sax._getNsTag()`` could fail with an exception on malformed input. + +* GH#467: Some test adaptations were made for libxml2 2.15. + Patch by Nick Wellnhofer. + +* LP2119510, GH#473: A Python compatibility test was fixed for Python 3.14+. + Patch by Lumír Balhar. + +* GH#471: Wheels for "riscv64" on recent Python versions were added. + Patch by ffgan. + +* GH#469: The wheel build no longer requires the ``wheel`` package unconditionally. + Patch by Miro Hrončok. + +* Binary wheels use the library version libxml2 2.14.5. + See https://gitlab.gnome.org/GNOME/libxml2/-/releases/v2.14.5 + +* Windows binary wheels continue to use a security patched library version libxml2 2.11.9. + + +6.0.0 (2025-06-26) +================== + +Features added +-------------- + +* GH#463: ``lxml.html.diff`` is faster and provides structurally better diffs. + Original patch by Steven Fernandez. + +* GH#405: The factories ``Element`` and ``ElementTree`` can now be used in type hints. + +* GH#448: Parsing from ``memoryview`` and other buffers is supported to allow zero-copy parsing. + +* GH#437: ``lxml.html.builder`` was missing several HTML5 tag names. + Patch by Nick Tarleton. + +* GH#458: ``CDATA`` can now be written into the incremental ``xmlfile()`` writer. + Original patch by Lane Shaw. + +* A new parser option ``decompress=False`` was added that controls the automatic + input decompression when using libxml2 2.15.0 or later. Disabling this option + by default will effectively prevent decompression bombs when handling untrusted + input. Code that depends on automatic decompression must enable this option. + Note that libxml2 2.15.0 was not released yet, so this option currently has no + effect but can already be used. + +* The set of compile time / runtime supported libxml2 feature names is available as + ``etree.LIBXML_COMPILED_FEATURES`` and ``etree.LIBXML_FEATURES``. + This currently includes + ``catalog``, ``ftp``, ``html``, ``http``, ``iconv``, ``icu``, + ``lzma``, ``regexp``, ``schematron``, ``xmlschema``, ``xpath``, ``zlib``. + +Bugs fixed +---------- + +* GH#353: Predicates in ``.find*()`` could mishandle tag indices if a default namespace is provided. + Original patch by Luise K. + +* GH#272: The ``head`` and ``body`` properties of ``lxml.html`` elements failed if no such element + was found.

It now returns a plain string. + +* LP#2109931: When building lxml with coverage reporting, it now disables the ``sys.monitoring`` + support due to the lack of support in https://github.com/nedbat/coveragepy/issues/1790 + +Other changes +------------- + +* Support for Python < 3.8 was removed. + +* Parsing directly from zlib (or lzma) compressed data is now considered an optional + feature in lxml. It may get removed from libxml2 at some point for security reasons + (compression bombs) and is therefore no longer guaranteed to be available in lxml. + + As of this release, zlib support is still normally available in the binary wheels + but may get disabled or removed in later (x.y.0) releases. To test the availability, + use ``"zlib" in etree.LIBXML_FEATURES``. + +* The ``Schematron`` class is deprecated and will become non-functional in a future lxml version. + The feature will soon be removed from libxml2 and stop being available. + +* GH#438: Wheels include the ``arm7l`` target. + +* GH#465: Windows wheels include the ``arm64`` target. + Patch by Finn Womack. + +* Binary wheels use the library versions libxml2 2.14.4 and libxslt 1.1.43. + Note that this disables direct HTTP and FTP support for parsing from URLs. + Use Python URL request tools instead (which usually also support HTTPS). + To test the availability, use ``"http" in etree.LIBXML_FEATURES``. + +* Windows binary wheels use the library versions libxml2 2.11.9, libxslt 1.1.39 and libiconv 1.17. + They are now based on VS-2022. + +* Built using Cython 3.1.2. + +* The debug methods ``MemDebug.dump()`` and ``MemDebug.show()`` were removed completely. + libxml2 2.13.0 discarded this feature. + + +5.4.0 (2025-04-22) +================== + +Bugs fixed +---------- + +* LP#2107279: Binary wheels use libxml2 2.13.8 and libxslt 1.1.43 to resolve several CVEs. + (Binary wheels for Windows continue to use a patched libxml2 2.11.9 and libxslt 1.1.39.) + Issue found by Anatoly Katyushin. + + +5.3.2 (2025-04-05) +================== + +This release resolves CVE-2025-24928 as described in +https://gitlab.gnome.org/GNOME/libxml2/-/issues/847 + +Bugs fixed +---------- + +* Binary wheels use libxml2 2.12.10 and libxslt 1.1.42. + +* Binary wheels for Windows use a patched libxml2 2.11.9

``DTD(external_id="…")`` erroneously required a byte string as ID value. + +* GH#450: ``iterparse()`` internally triggered the `DeprecationWarning`` added in lxml 5.3.0 when parsing HTML. + +Other changes +------------- + +* GH#442: Binary wheels for macOS no longer use the linker flag ``-flat_namespace``. + + +5.3.0 (2024-08-10) +================== + +Features added +-------------- + +* GH#421: Nested ``CDATA`` sections are no longer rejected but split on output + to represent ``]]>`` correctly. + Patch by Gertjan Klein. + +Bugs fixed +---------- + +* LP#2060160: Attribute values serialised differently in ``xmlfile.element()`` and ``xmlfile.write()``. + +* LP#2058177: The ISO-Schematron implementation could fail on unknown prefixes. + Patch by David Lakin. + +Other changes +------------- + +* LP#2067707: The ``strip_cdata`` option in ``HTMLParser()`` turned out to be useless and is now deprecated. + +* Binary wheels use the library versions libxml2 2.12.9 and libxslt

Patch by Michał Górny. + + +5.2.0 (2024-03-30) +================== + +Other changes +------------- + +* LP#1958539: The ``lxml.html.clean`` implementation suffered from several (only if used) + security issues in the past and was now extracted into a separate library: + + https://github.com/fedora-python/lxml_html_clean + + Projects that use lxml without "lxml.html.clean" will not notice any difference, + except that they won't have potentially vulnerable code installed. + The module is available as an "extra" setuptools dependency "lxml[html_clean]", + so that Projects that need "lxml.html.clean" will need to switch their requirements + from "lxml" to "lxml[html_clean]", or install the new library themselves. + +* The minimum CPU architecture for the Linux x86 binary wheels was upgraded to + "sandybridge" (launched 2011), and glibc 2.28 / gcc 12 (manylinux_2_28) wheels were added. + +* Built with Cython 3.0.10. + + +5.1.1 (2024-03-28) +================== + +Bugs fixed +---------- + +* LP#2048920: ``iterlinks()`` in ``lxml.html`` rejected ``bytes`` input in 5.1.0. + +* High source line numbers from the parser are no longer truncated + (up to a C ``long``) when using

the ``host_whitelist`` as list of characters and silently failed to reject any hosts. + Passing a non-collection is now rejected. + +Other changes +------------- + +* Support for Python 2.7 and Python versions < 3.6 was removed. + +* The wheel build was migrated to use ``cibuildwheel``. + Patch by Primož Godec. + + +5.0.2 (2024-03-28) +================== + +Other changes +------------- + +* GH#407: A compatibility test was adapted to recent expat versions. + Patch by Miro Hrončok. + +* Binary wheels use the library versions libxml2 2.12.6 and libxslt 1.1.39. + +* Built with Cython 3.0.9. + + +5.0.1 (2024-01-05) +================== + +Bugs fixed +---------- + +* LP#2046208: Parsing non-BMP Python Unicode strings could fail on macOS. + +* LP#2044225: When incrementally parsing broken HTML,

wheels in the 5.0.0 release did not validate cleanly (but installed ok). + + +.. _latest_release: + +5.0.0 (2023-12-29) +================== + +Features added +-------------- + +* Character escaping in ``C14N2`` serialisation now uses a single pass over the text + instead of searching for each unescaped character separately. + +* Early support for Python 3.13a2 was added. + +Bugs fixed +---------- + +* LP#1976304: The ``Element.addnext()`` method previously inserted the new element + before existing tail text. The tail text of both sibling elements now stays on + the respective elements. + +* LP#1980767, GH#379: ``TreeBuilder.close()`` could fail with a ``TypeError`` after + parsing incorrect input. Original patch by Enrico Minack. + +* ``Element.itertext(with_tail=False)`` returned the tail text of comments and + processing instructions, despite the explicit option. + +* GH#370: A crash with recent libxml2 2.11.x versions was resolved. + Patch by Michael Schlenker. + +* A compile problem with recent libxml2 2.12.x versions was resolved. + +* The internal exception handling in C callbacks was improved for Cython 3.0. + +* The exception declarations of ``xmlInputReadCallback``, ``xmlInputCloseCallback``, + ``xmlOutputWriteCallback`` and ``xmlOutputCloseCallback`` in ``tree.pxd`` were + corrected to prevent running Python code or calling into the C-API with a live + exception set. + +* GH#385: The long deprecated ``unittest.m̀akeSuite()`` function is no longer used. + Patch by Miro Hrončok. + +* LP#1522052: A file-system specific test is now optional and should no longer fail + on systems that don't support it. + +* GH#392: Some tests were adapted for libxml2 2.13. + Patch by Nick Wellnhofer. + +* Contains all fixes from lxml 4.9.4. + +Other changes +------------- + +* LP#1742885: lxml no longer expands external entities (XXE) by default to prevent + the security risk of loading arbitrary files and URLs. If this feature is needed, + it can be enabled in a backwards compatible way by using a parser with the option + ``resolve_entities=True``. The new default is ``resolve_entities='internal'``. + +* With libxml2 2.10.4 and later (as provided by the lxml 5.0 binary wheels), + parsing HTML tags with "prefixes" no longer builds a namespace dictionary + in ``nsmap`` but considers the ``prefix:name`` string the actual tag name. + With older libxml2 versions, since 2.9.11, the prefix was removed. Before + that, the prefix was parsed as XML prefix. + + lxml 5.0 does not try to hide this difference but now changes the ElementPath + implementation to let ``element.find("part1:part2")`` search for the tag + ``part1:part2`` in documents parsed as HTML, instead of looking only for ``part2``. + +* LP#2024343: The validation of the schema file itself is now optional in the + ISO-Schematron implementation. This was done because some lxml distributions + discard the RNG validation schema file due to licensing issues. The validation + can now always be disabled with ``Schematron(..., validate_schema=False)``. + It is enabled by default if available and disabled otherwise. The module + constant ``lxml.isoschematron.schematron_schema_valid_supported`` can be used + to detect whether schema file validation is available. + +* Some redundant and long deprecated methods were removed: + ``parser.setElementClassLookup()``, + ``xslt_transform.apply()``, + ``xpath.evaluate()``. + +* Some incorrect declarations were removed from ``python.pxd``. In general, this file + should not be used by external Cython code.
