Overview of changes in gcalctool 5.8.11 * Fixed bug #163538 (http://bugzilla.gnome.org/show_bug.cgi?id=163538) Backspace results in mal-formed expression. * = button is now also a one step undo. (This feature was temporary disabled by the previous redo/undo patch.) * Removed gotos from do_expression function.
