+ New feature
* Changed/Improved feature
! Fixed bug
- Removed feature

The last digit in the version number denotes bug-fix releases.

2.8.2:
    ! Fixed a parsing bug in the detection of output format in cases like:
        dot2tex --preproc example.dot | dot2tex
      Thanks Peter Collingbourne for the patch!
    - Removed obsolete shebang line from dot2tex.py

2.8.1:
    ! Fixed a severe bug in the preprocessing code for the tikz output format. 

2.8.0:
    ! Node names are now filtered to ensure that they are valid TikZ node names.
    ! Correct fill and stroke color is now set when using the tikz and pst output formats.

    ! Invisible nodes now generate zero-size coordinates when using the tikz
      output format. This allows drawing edges to/from invisible nodes.
    + Added dropshadows.dot and sportsbracket.dot examples.

    ! Concentrated edges are now supported in the pgf and pstricks output formats.
    ! The dot parser now correctly parses quoted string like:

        label="A \"quote\""
        label="\n\nA"

    ! The dot parser now supports concatenation of double quoted strings using
      the + character. Example:
           a [label="partA" + "partB" + "partC"];
    + Added support for edge compass points when using the tikz output format.
      Example: a.n -> b.e is translated to \draw (a.north) ... (b.east)
    * The external pydot module has been replaced with a custom version
      of the pydot's dot parser. Available in the dotparsing.py file.
    + Added support for file input. If the input data contains the line
      \input{filename.dot}
      filename.dot will be loaded and processed. (Thanks Kim Sullivan for the idea)
    + Added interface for using dot2tex as a library. Example:

           import dot2tex
           testgraph="digraph G {a_1-> a_2 -> a_3 -> a_1;}"
           texcode = dot2tex.dot2tex(testgraph,format='tikz',crop=True)

v 2.7.0
    + Added the --codeonly option. When this option is used, only draw
      commands are generated. Intended for use with the dot2texi package.
    * Minor improvements to the documentation.
    + Added graphanndtti.tex example.

v 2.6.1
    ! Fixed missing header in the file dot2tex/dotex
    ! Fixed various typos in the documentation

v 2.6.0
    + Added the --autosize option. Equivalent to
      > dot2tex --preproc ex.dot | dot2tex
    + Added the --prog option for choosing between dot, neato, circo, towpi
      and fdp, when the input is in plain dot format.
    + Added the special d2toptions graph attribute. Allows you to specify
      dot2tex options in command line format.
    * Added a dot2tex wrapper script and changed setup.py to make it fully
      compatible with both setuptools and distutils. A dot2tex module will
      now be put in the site-packages directory and a wrapper script in the
      scripts directory.
    ! Fixed typo in error message.
    + Added --runtests option to run doc tests (experimental).
    ! Fixed issue with wrong template when both  the --preview and --figonly
      options were used.

v 2.5.0
    + Added the TikZ output format (-f tikz)
    + Added the lblstyle attribute for styling graph, node and edge labels.
      (PGF and TikZ only)
    + Added the --tikzedgelabels option for placing edge labels without
      using xdot edge label information (tikz and pgf output format only).
    + Added a topath edge attribute for using TikZ' to paths (tikz and
      pgf only).
    * Information about the selected output format is now stored in the graph
      generated in preprocessing mode. No longer necessary to specify an
      output format in the final run.
    ! Edges with the same source and dest are now handled correctly in
      preprocessing mode. Only the edge defined last was preprocessed.
    + Added the --nodeoptions and --edgeoptions options and corresponding
      d2tnodeoptions and d2tedgeoptions graph attribute (tikz only).
    + Added the exstyle attribute. Ignored in preprocessing mode. (pgf and
      tikz only)

v 2.0.3
    ! Special TeX char escape code rewritten. Now works as intended.
      The $ character was not properly escaped.
    ! Added & to list of special characters.


v 2.0.2
    ! Fixed a severe bug in the interpretation of color attributes in edges.
      Colors were not reset after a change to a single edge color.

v 2.0.1
    ! Node margins are now interpreted correctly for nodes with size < minsize.
    ! Nodes now grow correctly to fit labels when size > minsize
    * Updated documentation with an example on how to change node sizes.

v 2.0.0
    ! Fixed a number of preprocessing bug related to how node attributes are
      interpreted.
    + Added automata.dot example.

v 2.0.0b
    * Changed the name of the --preview option to --crop.
    + Added the --preproc option for preprocessing labels with preview.sty.
    + Added the --debug option. Writes detailed debug information to dot2tex.log.
    ! The ^ char is now properly escaped.
    * Default PGF/TikZ template now requires PGF v >= 1.09.
    + Added new template tags to support preprocessing mode.
    + Templates for preprocessing, output and figonly mode can now be put
      in the same file.
    + Added the --alignstr option.
    + Added the --valignmode option.
    + Added the --usepdflatex option.

v 1.5.0
    # Released 2006-10-22
    * Added a few more helpfull error messages.
    + Added the --figonly option.
    ! The $ character is now properly escaped.
    ! Fixed a few issues when converting between Graphviz to backend styles.
    ! Fixed scoping issues when drawing edges in duplicate mode.

v 1.5.0b2
    ! Added more intelligent detection of xdot input. Older versions of
      Graphviz does not include the 'xdotversion' attribute in the
      output.

v 1.5.0b
    + Styles are now transfered to the PSTricks and PGF/TikZ backend.
    + Added a force straight line option to avoid using curves for
      straight edges.
    * PGF/TikZ is now set as the default backend.
    ! Fixed a line ending issue in data converted internally to the xdot format.
    + Added the -V version command line switch

    + Added option for switching node and graph draw order.
    ! Fixed bug in PGF/TikZ color handling
    + Added the --preview option to crop graphs
    + Added --figpreamble and --figpostamble options and graph attributes.
    + Added --docpreamble option and d2tdocpreamble graph attribute
    + Added --graphstyle option
    + Added --gvcols option
    * Changed default PGF/TikZ arrow type to >=latex'

v 1.0.1
    * Fixed bug in gvcols.tex

v 1.0.0
