Lxml

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

Features added
--------------

* ``ElementTree.write()`` has a new option ``doctype`` that writes out a
doctype string before the serialisation, in the same way as ``tostring()``.

* GH220: ``xmlfile`` allows switching output methods at an element level.
Patch by Burak Arslan.

* LP1595781, GH240: added a PyCapsule Python API and C-level API for
passing externally generated libxml2 documents into lxml.

* GH244: error log entries have a new property ``path`` with an XPath
expression (if known, None otherwise) that points to the tree element
responsible for the error. Patch by Bob Kline.

* The namespace prefix mapping that can be used in ElementPath now injects
a default namespace when passing a None prefix.

Bugs fixed
----------

* GH238: Character escapes were not hex-encoded in the ``xmlfile`` serialiser.
Patch by matejcik.

* GH229: fix for externally created XML documents. Patch by Theodore Dubois.

* LP1665241, GH228: Form data handling in lxml.html no longer strips the
option values specified in form attributes but only the text values.
Patch by Ashish Kulkarni.

* LP1551797: revert previous fix for XSLT error logging as it breaks
multi-threaded XSLT processing.

* LP1673355, GH233: ``fromstring()`` html5parser failed to parse byte strings.

Other changes
-------------

* The previously undocumented ``docstring`` option in ``ElementTree.write()``
produces a deprecation warning and will eventually be removed.

serialises like ``<div attrname></div>``. Patch by Daniel Holth.

* GH197: Ignore form input fields in ``form_values()`` when they are
marked as ``disabled`` in HTML. Patch by Kristian Klemon.
