• 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.
