- Added a helper to "optimize" regular expressions that match one of many
  literal words; this can save 20% and more lexing time with lexers that
  highlight many keywords or builtins.

- New styles: "xcode" and "igor", similar to the default highlighting of
  the respective IDEs.

- The command-line "pygmentize" tool now tries a little harder to find the
  correct encoding for files and the terminal (#979).

- Added "inencoding" option for lexers to override "encoding" analogous
  to "outencoding" (#800).

- Added line-by-line "streaming" mode for pygmentize with the "-s" option.
  (PR#165)  Only fully works for lexers that have no constructs spanning
  lines!

- Added an "envname" option to the LaTeX formatter to select a replacement
  verbatim environment (PR#235).

- Updated the Makefile lexer to yield a little more useful highlighting.

- Lexer aliases passed to ``get_lexer_by_name()`` are now case-insensitive.

- File name matching in lexers and formatters will now use a regex cache
  for speed (PR#205).

- Pygments will now recognize "vim" modelines when guessing the lexer for
  a file based on content (PR#118).

- The NameHighlightFilter now works with any Name.* token type (#790).

- Python 3 lexer: add new exceptions from PEP 3151.

- Opa lexer: add new keywords (PR#170).

  literals (PR#176).

  guessing so that plain XML isn't always taken as Lasso (PR#163).

Version 0.11
------------
(codename Straußenei, released Aug 23, 2008)

fixes and new features.

- Lexers added:

  * YAML, thanks to Kirill Simonov
  * ActionScript 3, thanks to Pierre Bourdon
  * Cheetah/Spitfire templates, thanks to Matt Good
  * Lighttpd config files
  * Nginx config files
  * Gnuplot plotting scripts
  * Clojure
  * POV-Ray scene files
  * Sqlite3 interactive console sessions
  * Scala source files, thanks to Krzysiek Goj

- Lexers improved:

  * C lexer highlights standard library functions now and supports C99
    types.
  * Bash lexer now correctly highlights heredocs without preceding
    whitespace.
  * Vim lexer now highlights hex colors properly and knows a couple
    more keywords.
  * Irc logs lexer now handles xchat's default time format (#340) and
    correctly highlights lines ending in ``>``.
  * Support more delimiters for perl regular expressions (#258).
  * ObjectiveC lexer now supports 2.0 features.

- Added "Visual Studio" style.

- Updated markdown processor to Markdown 1.7.

- Support roman/sans/mono style defs and use them in the LaTeX
  formatter.

- The RawTokenFormatter is no longer registered to ``*.raw`` and it's
  documented that tokenization with this lexer may raise exceptions.

- 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.


Version 0.10
------------
(codename Malzeug, released May 06, 2008)

- Lexers added:

  * Io
  * Smalltalk

  * 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.

  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.

-------------
(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.
