4.6.2 (2020-11-26)

Bugs fixed

4.6.0 (2020-10-17)

Features added

• GH#310: 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

• LP#1869455: 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.
