 ## CHANGELOG:
 ## ====================
+##  Version 1.3
+##  1. Made definition of "hack" GetMark conditional on base class not
+##     implementing it properly, to allow for migration in wx code base
+##     while taking advantage of improvements therein for some platforms.
+##
 ##  Version 1.2
 ##  1. Converted docstrings to reST format, added doc for ePyDoc.
 ##  2. Renamed helper functions, vars etc. not intended to be visible in public
