+Version 0.8.1 (2007.04.17):
+ * changed: on win9x the configuration file is in a folder like:
+ "c:\windows\data application\ttcalc\" now
+ * changed: the program uses the TTMath 0.8.1 now
+ * added: from TTMath 0.8.1:
+ root(x, index), bitand(x,y), bitor(x,y), bitxor(x,y)
+ /band(x,y), bor(x,y), bxor(x,y)/
+ asinh(x), acosh(x), atanh(x), acoth(x) /atgh(x), actgh(x)/
+ * changed: from TTMath 0.8.1: calculations are much faster now
+ especially the factorial() function
+ * changed: from TTMath 0.8.1: the way of parsing operators
+
Version 0.8.0 (2007.04.02):
* added: the del key deletes a variable or a function now
(if the focus is on the list)
