Changelog
### 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
attrib mapping during element creation.
* LP1838521: The package metadata now lists the supported Python versions.
```
### 4.4.0
```
==================
Features added
--------------
* ``Element.clear()`` accepts a new keyword argument ``keep_tail=True`` to clear
everything but the tail text. This is helpful in some document-style use cases
and for clearing the current element in ``iterparse()`` and pull parsing.
* When creating attributes or namespaces from a dict in Python 3.6+, lxml now
preserves the original insertion order of that dict, instead of always sorting
the items by name. A similar change was made for ElementTree in CPython 3.8.
See https://bugs.python.org/issue34160
* Integer elements in ``lxml.objectify`` implement the ``__index__()`` special method.
* GH269: Read-only elements in XSLT were missing the ``nsmap`` property.
Original patch by Jan Pazdziora.
* ElementInclude can now restrict the maximum inclusion depth via a ``max_depth``
argument to prevent content explosion. It is limited to 6 by default.
* The ``target`` object of the XMLParser can have ``start_ns()`` and ``end_ns()``
callback methods to listen to namespace declarations.
* The ``TreeBuilder`` has new arguments ``comment_factory`` and ``pi_factory`` to
pass factories for creating comments and processing instructions, as well as
flag arguments ``insert_comments`` and ``insert_pis`` to discard them from the
tree when set to false.
* A `C14N 2.0 <https://www.w3.org/TR/xml-c14n2/>`_ implementation was added as
``etree.canonicalize()``, a corresponding ``C14NWriterTarget`` class, and
a ``c14n2`` serialisation method.
Bugs fixed
----------
* When writing to file paths that contain the URL escape character '%', the file
path could wrongly be mangled by URL unescaping and thus write to a different
file or directory. Code that writes to file paths that are provided by untrusted
sources, but that must work with previous versions of lxml, should best either
reject paths that contain '%' characters, or otherwise make sure that the path
does not contain maliciously injected '%XX' URL hex escapes for paths like '../'.
* Assigning to Element child slices with negative step could insert the slice at
the wrong position, starting too far on the left.
* Assigning to Element child slices with overly large step size could take very
long, regardless of the length of the actual slice.
* Assigning to Element child slices of the wrong size could sometimes fail to
raise a ValueError (like a list assignment would) and instead assign outside
of the original slice bounds or leave parts of it unreplaced.
* The ``comment`` and ``pi`` events in ``iterwalk()`` were never triggered, and
instead, comments and processing instructions in the tree were reported as
``start`` elements. Also, when walking an ElementTree (as opposed to its root
element), comments and PIs outside of the root element are now reported.
* LP1827833: The RelaxNG compact syntax support was broken with recent versions
of ``rnc2rng``.
* LP1758553: The HTML elements ``source`` and ``track`` were added to the list
of empty tags in ``lxml.html.defs``.
* Registering a prefix other than "xml" for the XML namespace is now rejected.
* Failing to write XSLT output to a file could raise a misleading exception.
It now raises ``IOError``.
Other changes
-------------
* Support for Python 3.4 was removed.
* When using ``Element.find*()`` with prefix-namespace mappings, the empty string
is now accepted to define a default namespace, in addition to the previously
supported ``None`` prefix. Empty strings are more convenient since they keep
all prefix keys in a namespace dict strings, which simplifies sorting etc.
* The ``ElementTree.write_c14n()`` method has been deprecated in favour of the
long preferred ``ElementTree.write(f, method="c14n")``. It will be removed
in a future release.
```
### 4.3.5
```
==================
* Rebuilt with Cython 0.29.13 to support Python 3.8.
```
### 4.3.4
```
==================
* Rebuilt with Cython 0.29.10 to support Python 3.8.
