  much difference between the two versions).

0.4.2 (7 January 2018)

--------------------

* Fix for ``type_.lower()`` bug: pybtex 0.18 expects type to be a
  string (this fixes issue #68 reported by jluttine).

0.3.0 (4 May 2014)
------------------

* **BACKWARD INCOMPATIBLE**
  The alpha style is now default, so citations are labelled in a way
  that is more standard for Sphinx. To get the old behaviour back, add
  ``:style: plain`` to your bibliography directives.

* **BACKWARD INCOMPATIBLE**
  :meth:`~sphinxcontrib.bibtex.cache.Cache.is_cited` has been removed.
  Use :meth:`~sphinxcontrib.bibtex.cache.Cache.get_cited_docnames` instead,
  which will return an empty list for keys that are not cited.

* Improved support for local bibliographies (see issues #52, #62, and
  #63; test case provided by Boris Kheyfets):

  - New ``docname`` and ``docnames`` filter identifiers.

  - Filter expressions now also support set literals and the operators
    ``in``, ``not in``, ``&``, and ``|``.

  See documentation for details.

* Multiple comma-separated citation keys per cite command (see issue
  #61, suggested by Boris Kheyfets).

* Add support for pypy and Python 3.4.

* Drop support for Python 2.6 and Python 3.2.

  single code base.

* Various test suite improvements.

0.2.9 (9 October 2013)
----------------------

* Upgrade to the latest pybtex-docutils to produce more optimal html output
  (specifically: no more nested ``<span>``\ s).

* Remove latex codec code, and rely on latexcodec package instead.

* :class:`FilterVisitor` has been removed from the public API.
  Use :meth:`~sphinxcontrib.bibtex.cache.Cache.get_bibliography_entries`
  instead.

* Fix upstream Sphinx bug concerning LaTeX citation hyperlinks
  (contributed by erikb85; see pull request #45).

* Fix most pylint warnings, refactor code.

  and #34).

* Code is now mostly pep8 compliant.

0.2.6 (2 March 2013)
--------------------

* For unsorted styles, citation entries are now sorted in the order
  they are cited, instead of following the order in the bib file, to
  reflect more closely the way LaTeX handles unsorted styles
  (addresses issue #15).

* Skip citation label warnings on Sphinx [source] links (issue #17,
  contributed by Simon Clift).

0.2.5 (18 October 2012)
-----------------------

* Duplicate label detection (issue #14).

  multiple bibliographies with a numerical label style (addresses
  issue #14).

0.2.4 (24 August 2012)
----------------------

* New options for the bibliography directive for rendering the
  bibliography as bullet lists or enumerated lists: ``:list:``,
  ``:enumtype:``, and ``:start:``.

* Minor latex codec fixes.

* Turn exception into warning when a citation cannot be relabeled
  (fixes issue #2).

* Document LaTeX encoding, and how to turn it off (issue #4).

* Use pybtex labels (fixes issue #6 and issue #7).

  counts (fixes issues with citations in repeated Sphinx runs).
