Log message:
py-lxml: updated to 4.2.5

4.2.5:
Bugs fixed
Javascript URLs that used URL escaping were not removed by the HTML cleaner.

Log message:
py-lxml: updated to 4.2.4

4.2.4:
Features added
* Allow using pkg-config for build configuration.

Bugs fixed
* Crash when moving an element to another document with
  Element.insert().

Log message:
py-lxml: updated to 4.2.3

4.2.3:
Reverted GH-265: lxml links against zlib as a shared library again.

Log message:
py-lxml: updated to 4.2.2

4.2.2:
Bugs fixed
* GH266: Fix sporadic crash during GC when parse-time schema validation is used
  and the parser participates in a reference cycle.
* GH265: lxml no longer links against zlib as a shared library, only on static \ 
builds.

Log message:
py-lxml: updated to 4.2.1

4.2.1:
Bugs fixed
* iterwalk() failed to return the ‘start’ event for the initial element if a \ 
tag selector is used.
* Failure to import 4.2.0 into PyPy due to a missing library symbol.
* Add “-isysroot” linker option on MacOS as needed by XCode 9.

Log message:
py-lxml: updated to 4.2.0

4.2.0:
Features added
* SelectElement.value returns more standard-compliant and browser-like defaults \ 
for non-multi-selects. If no option is selected, the value of the first option \ 
is returned (instead of None). If multiple options are selected, the value of \ 
the last one is returned (instead of that of the first one). If no options are \ 
present (not standard-compliant) SelectElement.value still returns None.
* The HTMLParser() now supports the huge_tree option. Patch by stranac.

Bugs fixed
* Some XSLT messages were not captured by the transform error log.
* Crash at shutdown after an interrupted iterparse run with XMLSchema validation.

Log message:
py-lxml: updated to 4.1.1

4.1.1:
* Rebuild with Cython 0.27.3 to improve support for Py3.7.

Log message:
py-lxml: update to 4.1.0

4.1.0:
Features added
* ElementPath supports text predicates for current node, like “[.=’text’]”.
* ElementPath allows spaces in predicates.
* Custom Element classes and XPath functions can now be registered with a \ 
decorator rather than explicit dict assignments.
* Static Linux wheels are now built with link time optimisation (LTO) enabled. \ 
This should have a beneficial impact on the overall performance by providing a \ 
tighter compiler integration between lxml and libxml2/libxslt.

Bugs fixed
* Requesting non-Element objects like comments from a document with \ 
PythonElementClassLookup could fail with a TypeError.

Log message:
py-lxml: remove comment about (fixed) test failure

Log message:
py-lxml: update to 4.0.0

4.0.0:

Features added
--------------
* The ElementPath implementation is now compiled using Cython,
  which speeds up the ``.find*()`` methods quite significantly.

* The modules ``lxml.builder``, ``lxml.html.diff`` and ``lxml.html.clean``
  are also compiled using Cython in order to speed them up.

* ``xmlfile()`` supports async coroutines using ``async with`` and ``await``.

* ``iterwalk()`` has a new method ``skip_subtree()`` that prevents walking into
  the descendants of the current element.

* ``RelaxNG.from_rnc_string()`` accepts a ``base_url`` argument to
  allow relative resource lookups.

* The XSLT result object has a new method ``.write_output(file)`` that serialises
  output data into a file according to the ``<xsl:output>`` configuration.

Bugs fixed
----------
* GH-251: HTML comments were handled incorrectly by the soupparser.
  Patch by mozbugbox.

* LP-1654544: The html5parser no longer passes the ``useChardet`` option
  if the input is a Unicode string, unless explicitly requested.  When parsing
  files, the default is to enable it when a URL or file path is passed (because
  the file is then opened in binary mode), and to disable it when reading from
  a file(-like) object.

  Note: This is a backwards incompatible change of the default configuration.
  If your code parses byte strings/streams and depends on character detection,
  please pass the option ``guess_charset=True`` explicitly, which already worked
  in older lxml versions.

* LP-1703810: ``etree.fromstring()`` failed to parse UTF-32 data with BOM.

* LP-1526522: Some RelaxNG errors were not reported in the error log.

* LP-1567526: Empty and plain text input raised a TypeError in soupparser.

* LP-1710429: Uninitialised variable usage in HTML diff.

* LP-1415643: The closing tags context manager in ``xmlfile()`` could continue
  to output end tags even after writing failed with an exception.

* LP-1465357: ``xmlfile.write()`` now accepts and ignores None as input argument.

* Compilation under Py3.7-pre failed due to a modified function signature.

Other changes
-------------
* The main module source files were renamed from ``lxml.*.pyx`` to plain
  ``*.pyx`` (e.g. ``etree.pyx``) to simplify their handling in the build
  process.  Care was taken to keep the old header files as fallbacks for
  code that compiles against the public C-API of lxml, but it might still
  be worth validating that third-party code does not notice this change.
