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

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. Use the C-API declarations provided by
  Cython itself instead.

• Binary wheels use the library versions libxml2 2.12.3 and libxslt 1.1.39.

• Built with Cython 3.0.7, updated to follow recent changes in Cython 3.1-dev.
