GRAMMATICA VERSION INFORMATION
==============================

Version 0.3 (2003-05-04):
-------------------------

    o Created XML generated documentation
      The release documentation is now available in both text and 
      HTML format. Both formats are generated with XSLT from a single 
      source.

    o Added look-ahead loop detection
      The look-ahead calculation now detects grammar loops and all 
      grammar ambiguities. It should no longer be possible to cause 
      infinite loops with a malformed grammar.

    o Added ambiguity resolution inside alternatives
      Some ambiguities inside productions couldn't previously be 
      resolved by the LL(k) parser. Productions like ["one"] "one" 
      "two" contain an ambiguity between the first element and the 
      second, but it is not inherent. This is now handled correctly 
      by adding look-ahead sets for individual production elements.

    o Added expected tokens to parse errors
      The parse error exceptions now contains a list of the expected 
      tokens for the unexpected token errors.

    o Added automatic unit tests for the parser
      A JUnit class testing the LL(k) parser has been added. These 
      tests are executed upon every build to verify the integrity of 
      the parser.


Version 0.2 (2003-04-20):
-------------------------

    o Addition of an internal regular expression library
      This improves tokenizer performance by at least 100% compared 
      to using the GNU RegExp library.

    o Addition of an analyzer framework with parser callbacks
      A code generator has also been added to create default methods 
      for all tokens and productions in the grammar.

    o Major refactorings of the tokenizer and parser classes
      Various other classes have also been improved to simplify 
      future feature additions.


Version 0.1 (2003-03-29):
-------------------------

    o First alpha release
