[lxml-dev] lxml 2.1alpha1 released

[Stefan Behnel]

Hi all,

the first alpha release of lxml 2.1 is on PyPI. This is a "cleanup and new
features" release that follows the current stable 2.0 series. The major new
features are XSLT extension elements and support for comments/PIs in iterparse().

A lot of formerly deprecated API functions were finally removed, so you may
have to adapt your code (a little). After the change, it will continue to run
with both lxml 2.0.x and 2.1.

Have fun,
Stefan


2.1alpha1 (2008-03-27)

Features added

    * New event types 'comment' and 'pi' in iterparse().
    * XSLTAccessControl instances have a property options that returns a
      dict of access configuration options.
    * Constant instances DENY_ALL and DENY_WRITE on XSLTAccessControl class.
    * Extension elements for XSLT (experimental!)
    * Element.base property returns the xml:base or HTML base URL of an
      Element.
    * docinfo.URL property is writable.

Bugs fixed

    * Default encoding for plain text serialisation was different from that
      of XML serialisation (UTF-8 instead of ASCII).

Other changes

    * Minor API speed-ups.
    * The benchmark suite now uses tail text in the trees, which makes the
      absolute numbers incomparable to previous results.
    * Generating the HTML documentation now requires Pygments, which is used
      to enable syntax highlighting for the doctest examples.

Most long-time deprecated functions and methods were removed:

    * etree.clearErrorLog(), use
      etree.clear_error_log()
    * etree.useGlobalPythonLog(), use
      etree.use_global_python_log()
    * etree.ElementClassLookup.setFallback(), use
      etree.ElementClassLookup.set_fallback()
    * etree.getDefaultParser(), use
      etree.get_default_parser()
    * etree.setDefaultParser(), use
      etree.set_default_parser()
    * etree.setElementClassLookup(), use
      etree.set_element_class_lookup()

      Note that parser.setElementClassLookup() has not been removed yet,
      although parser.set_element_class_lookup() should be used instead.

    * xpath_evaluator.registerNamespace(), use
      xpath_evaluator.register_namespace()
    * xpath_evaluator.registerNamespaces(), use
      xpath_evaluator.register_namespaces()
    * objectify.setPytypeAttributeTag, use
      objectify.set_pytype_attribute_tag
    * objectify.setDefaultParser(), use
      objectify.set_default_parser()
