  - Bash lexer now correctly highlights heredocs without preceding whitespace.
  - Vim lexer now highlights hex colors properly and knows a couple more keywords.

- New option `hl_lines` to HTML formatter, to highlight certain lines.
- New option `prestyles` to HTML formatter.
- New option -g to pygmentize, to allow lexer guessing based on filetext (can be slowish, so file extensions are still checked first).
- `guess_lexer()` now makes its decision much faster due to a cache of whether data is xml-like (a check which is used in several versions of `analyse_text()`. Several lexers also have more accurate `analyse_text()` now.

  - Vim Script, by Tim Hatch
- The HTML formatter now has a second line-numbers mode in which it will just integrate the numbers in the same `<pre>` tag as the code.
- The CSharpLexer now is Unicode-aware, which means that it has an option that can be set so that it correctly lexes Unicode identifiers allowed by the C# specs.
- Added a RaiseOnErrorTokenFilter that raises an exception when the lexer generates an error token, and a VisibleWhitespaceFilter that converts whitespace (spaces, tabs, newlines) into visible characters.
- Fixed the do_insertions() helper function to yield correct indices.
- The ReST lexer now automatically highlights source code blocks in ".. sourcecode:: language" and ".. code:: language" directive blocks.
- Improved the default style (thanks to Tiberius Teng). The old default is still available as the "emacs" style (which was an alias before).
- The get_style_defs method of HTML formatters now uses the cssclass option as the default selector if it was given.

- Included a built version of the documentation in the source tarball.

### Version 0.7

(codename Faschingskrapfn, released Feb 14, 2007)

- Added a MoinMoin parser that uses Pygments. With it, you get Pygments highlighting in Moin Wiki pages.
- Changed the exception raised if no suitable lexer, formatter etc. is found in one of the get_*_by_* functions to a custom exception, pygments.util.ClassNotFound. It is, however, a subclass of ValueError in order to retain backwards compatibility.
- Added a -H command line option which can be used to get the docstring of a lexer, formatter or filter.
- Made the handling of lexers and formatters more consistent. The aliases and filename patterns of formatters are now attributes on them.
- Added an OCaml lexer, thanks to Adam Blinkinsop.
- Made the HTML formatter more flexible, and easily subclassable in order to make it easy to implement custom wrappers, e.g. alternate line number markup. See the documentation.
- Added an outencoding option to all formatters, making it possible to override the encoding (which is used by lexers and formatters) when using the command line interface. Also, if using the terminal formatter and the output file is a terminal and has an encoding attribute, use it if no encoding is given.
- Made it possible to just drop style modules into the styles subpackage of the Pygments installation.
- Added a "state" keyword argument to the using helper.
- Added a commandprefix option to the LatexFormatter which allows to control how the command names are constructed.
- Added quite a few new lexers, thanks to Tim Hatch:
  - Java Server Pages
  - Windows batch files
  - Trac Wiki markup
  - Python tracebacks
  - ReStructuredText
  - Dylan
  - and the Befunge esoteric programming language (yay!)
