Changes in version 3.0
======================


:program:`Universal Feed Parser` 3.0 was released on June 21, 2004.

- don't try ``iso-8859-1`` (can't distinguish between ``iso-8859-1`` and ``windows-1252`` anyway, and most incorrectly marked feeds are ``windows-1252``)

- fixed regression that could cause the same encoding to be tried twice (even if it failed the first time)


:program:`Universal Feed Parser` 3.0fc3 was released on June 18, 2004.

- fixed bug in ``_changeEncodingDeclaration`` that failed to parse UTF-16 encoded feeds

- made ``source`` into a FeedParserDict

- duplicate admin:generatorAgent/@rdf:resource in ``generator_detail.url``

- added support for image

- refactored ``parse()`` fallback logic to try other encodings if SAX parsing fails (previously it would only try other encodings if re-encoding failed)

- remove ``unichr`` madness in normalize_attrs now that we're properly tracking encoding in and out of BaseHTMLProcessor

- set ``feed.language`` from root-level xml:lang

- set ``entry.id`` from rdf:about

- send ``Accept`` header

:program:`Universal Feed Parser` 3.0b22 was released on April 19, 2004.

- work around embedded illformed :abbr:`HTML (HyperText Markup Language)` with half a DOCTYPE

- work around malformed ``Content-Type`` header

- if character encoding is wrong, try several common ones before falling back to regexes (if this works, ``bozo_exception`` is set to ``CharacterEncodingOverride``

- fixed character encoding issues in BaseHTMLProcessor by tracking encoding and converting from Unicode to raw strings before feeding data to sgmllib.SGMLParser
