Release Notes

lxml/lxml (lxml)

v4.9.1

Compare Source

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

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.

v4.9.0

Compare Source

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

Bugs fixed

• GH#341: 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).

• GH#343: Windows-AArch64 build support in Visual Studio.
  Patch by Steve Dower.

v4.8.0

Compare Source

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

Features added

• GH#337: 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

• GH#338: 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.

v4.7.1

Compare Source

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

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/[email protected]/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.

• LP#1939031: 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).

v4.6.5

Compare Source

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

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).

v4.6.4

Compare Source

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

Features added

• GH#317: A new property system_url was added to DTD entities.
  Patch by Thirdegree.

  Patch by Isaac Jurado.

v4.6.3

Compare Source

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

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.

v4.6.2

Compare Source

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

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.

v4.6.1

Compare Source

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

Bugs fixed

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

Features added

  should have raised XMLSyntaxError. It now raises a combined exception to
  keep up backwards compatibility, while switching to XMLSyntaxError as an
  interface.
