+Version 0.8.2 portable (2007.07.01):
+	* added: the portable version of the program TTCalc
+	  it uses *.ini config file from the same folder where
+	  is the executable file, and it's much smaller in size
+	  (in the portable version there's only one kind
+	  of precision and the program is packed with UPX - 
+	  the Ultimate Packer for eXecutables)
+	  there are no other differences between version 0.8.1 and this one
+		 
 Version 0.8.1 (2007.04.17):
 	* changed: on win9x the configuration file is in a folder like:
 	  "c:\windows\data application\ttcalc\" now
