-Version 0.9.1 (2009.02.07):
+Version 0.9.2 (2010.09.24):
+    * added:   Italian translation made by
+               Damiano Monaco <dmonax at gmail.com>
+    * added:   menu: edit->swap (ctrl+W)
+               swapping the input for the output edit
+
+    Changes from TTMath 0.9.2 relating to TTCalc:
+    * fixed:   Big::Add() sometimes incorrectly rounded the last bit from its mantissa
+    * fixed:   Big::ToString method
+               in some cases when in the output string the exponent should be equal zero
+               the method changes the exponent to one so the last digit from the mantissa
+               was lost
+   
+
+Version 0.9.1 (2010.02.07):
     * fixed:   the pad window didn't take into account following options (from display tab):
                grouping, input commas and parameter separators
     * updated: Chinese translation
