May 04, 2007 - Release 0.4
---------------------------

 - Dynamically allocate more memory if the string buffer runs out of space when
   reading a String object from an input stream.
 - Added new arguments to configuration::find_parameter() to allow for a list of
   sections and a list of parameters in sections.
   The new arguments are section index and parameter index (default = 0).
 - Added a copy contructor to the regex class. This prevents multiple frees in the destructor.

Mar 29, 2003 - Patch 0.3.1
---------------------------

 - String constructor and assignment from char * are more robust from NULL pointers.
 - Bugfix in the configuration class: Do not read the config file in the home
   directory if the HOME environment variable doesn't exist.

Nov 22, 2002 - Release 0.3
--------------------------

 - New functions: String::escape(), String::unescape()
 - Uses the XML2 library
 - Bug Fixes in configuration class: segfault when finding a parameters
   that is not in the user-sepcific config tree.
   Check if a configuration file exists before feeding it to the XML parser.

Sep 28, 2002 - Patch 0.2.3
--------------------------

 - Bugfix: In configuration::find_parameter(), check if the parameter node exists
   before retrieving its contents.
 - New feature: substring selection by regular expression, with
      substring String::operator()(const regex &r);
 - Bugfix: Reading a String object from an istream now checks for
   end-of-file.
 - Bugfix: conversion of an empty string to a date or hour object
   now makes the values of such an object 0 (null) instead of giving
   a segmentation fault.
 - The class UTC combines the date and hour classes. The most basic
   functions of the UTC class are now implemented.
   These include constructors and conversion to and from String objects.
 - New functions: date::proper(), hour::proper() and UTC::proper().
   Return true if the object holds a proper clock time and/or calendar
   date; false if at least one value is out of range.

Sep 02, 2002 - Patch 0.2.2
--------------------------

 - date::format() is now properly implemented
 - New operator to read an 'hour' object from an istream:
    istream & operator >> (istream &, hour &)
 - New function 'String hour::format()'. The default format is HH:MM:SS
   in 24 hour clock.
 - New function 'hour now()' read the current time of day.

Jul 27, 2002 - Patch 0.2.1
---------------------------

 - Improved the XML library configuration.
 - BUG FIX: testaxe crashed without a config file.
 - Reinstated the metronome demo
 - BUG FIX: acltest.cpp included the obsolete complex number test.
