POCOSOLV UPDATES SUMMARY
------------------------

Version 1.0d: 5 March 2006
 1. The 8-bit solver is now available as a plugin DLL for Sokoban++ and
    compatible Sokoban software. See the user guide for more information.
 2. Recognizes '-' (hyphen) as an empty floor cell, in addition to ' '
    (space) and '_' (underscore), because it is also common in e-mail.
 3. Minor changes to output formatting.

Version 1.0c: 9 October 2005
 1. Version 1.0b in fact did not recognize '_' as an empty floor cell, as
    claimed below (see 1.). This change is now in effect.

Version 1.0b: 18 September 2005
 1. Recognizes '_' as an empty floor cell, in addition to ' '. To avoid
    unwanted formatting, some people use underscores instead of spaces when
    sending puzzles by e-mail.
 2. Allows the perimiter wall of a puzzle layout to define a non-rectangular
    shape by treating leading and trailing floor cells as wall cells.
 3. Updated user guide
 4. Added Updates.txt to files distributed in release

Version 1.0a: 21 August 2005
 1. Allows '/' as the command line parameter assignment operator as an
    alternative to '=', because batch files in a Windows command prompt may look
    for and swallow '='.
 2. Updated and made small corrections to the user guide

Version 1.0: 14 August 2005
 1. First release
