### Version 0.10

(codename Malzeug, released May 06, 2008)

- Lexers added:
  - Io
  - Smalltalk
  - Darcs patches
  - Tcl
  - Matlab
  - Matlab sessions
  - FORTRAN
  - XSLT
  - tcsh
  - NumPy
  - Python 3
  - S, S-plus, R statistics languages
  - Logtalk
- In the LatexFormatter, the commandprefix option is now by default 'PY' instead of 'C', since the latter resulted in several collisions with other packages. Also, the special meaning of the arg argument to `get_style_defs()` was removed.
- Added ImageFormatter, to format code as PNG, JPG, GIF or BMP. (Needs the Python Imaging Library.)
- Support doc comments in the PHP lexer.
- Handle format specifications in the Perl lexer.
- Fix comment handling in the Batch lexer.
- Add more file name extensions for the C++, INI and XML lexers.

- Fix function and interface name highlighting in the Java lexer.
- Fix at-rule handling in the CSS lexer.
- Handle KeyboardInterrupts gracefully in pygmentize.
- Added BlackWhiteStyle.
- Bash lexer now correctly highlights math, does not require whitespace after semicolons, and correctly highlights boolean operators.
- Makefile lexer is now capable of handling BSD and GNU make syntax.

### Version 0.9

(codename Herbstzeitlose, released Oct 14, 2007)

- Lexers added:
  - Erlang
  - ActionScript
  - Literate Haskell
  - Common Lisp
  - Various assembly languages
  - Gettext catalogs
  - Squid configuration
  - Debian control files
  - MySQL-style SQL
  - MOOCode
- Lexers improved:
  - Greatly improved the Haskell and OCaml lexers.
  - Improved the Bash lexer's handling of nested constructs.
  - The C# and Java lexers exhibited abysmal performance with some input code; this should now be fixed.
  - The IRC logs lexer is now able to colorize weechat logs too.
  - The Lua lexer now recognizes multi-line comments.
  - Fixed bugs in the D and MiniD lexer.
- The encoding handling of the command line mode (pygmentize) was enhanced. You shouldn't get UnicodeErrors from it anymore if you don't give an encoding option.
- Added a `-P` option to the command line mode which can be used to give options whose values contain commas or equals signs.
- Added 256-color terminal formatter.
- Added an experimental SVG formatter.
- Added the `lineanchors` option to the HTML formatter, thanks to Ian Charnas for the idea.
- Gave the line numbers table a CSS class in the HTML formatter.
- Added a Vim 7-like style.

### Version 0.8.1

(released Jun 27, 2007)

- Fixed POD highlighting in the Ruby lexer.
- Fixed Unicode class and namespace name highlighting in the C# lexer.
- Fixed Unicode string prefix highlighting in the Python lexer.
- Fixed a bug in the D and MiniD lexers.
- Fixed the included MoinMoin parser.

### Version 0.8

(codename Maikäfer, released May 30, 2007)

- Lexers added:
  - Haskell, thanks to Adam Blinkinsop
  - Redcode, thanks to Adam Blinkinsop
  - D, thanks to Kirk McDonald
  - MuPad, thanks to Christopher Creutzig
  - MiniD, thanks to Jarrett Billingsley
  - 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.
- Improved the ReST and Bash lexers a bit.
- Fixed a few bugs in the Makefile and Bash lexers, thanks to Tim Hatch.
- Fixed a bug in the command line code that disallowed `-O` options when using the `-S` option.
- Fixed a bug in the RawTokenFormatter.

### Version 0.7.1

(released Feb 15, 2007)

- Fixed little highlighting bugs in the Python, Java, Scheme and Apache Config lexers.
- Updated the included manpage.
- 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!)
- Added Mako lexers by Ben Bangert.
- Added "fruity" style, another dark background originally vim-based theme.
- Added sources.list lexer by Dennis Kaarsemaker.
- Added token stream filters, and a pygmentize option to use them.
- Changed behavior of in Operator for tokens.
- Added mimetypes for all lexers.
- Fixed some problems lexing Python strings.
- Fixed tickets: #167, #178, #179, #180, #185, #201.

### Version 0.6

(codename Zimtstern, released Dec 20, 2006)

- Added option for the HTML formatter to write the CSS to an external file in "full document" mode.
- Added RTF formatter.
- Added Bash and Apache configuration lexers (thanks to Tim Hatch).
- Improved guessing methods for various lexers.
- Added @media support to CSS lexer (thanks to Tim Hatch).
- Added a Groff lexer (thanks to Tim Hatch).
- License change to BSD.
- Added lexers for the Myghty template language.
- Added a Scheme lexer (thanks to Marek Kubica).
- Added some functions to iterate over existing lexers, formatters and lexers.
- The HtmlFormatter's get_style_defs() can now take a list as an argument to generate CSS with multiple prefixes.
- Support for guessing input encoding added.
- Encoding support added: all processing is now done with Unicode strings, input and output are converted from and optionally to byte strings (see the `encoding` option of lexers and formatters).
- Some improvements in the C(++) lexers handling comments and line continuations.
