2001/12/14 Calcoo 1.3.4

	* Changed: RPN mode: behavior of the <Enter> button
	           Finally calcoo can satisfy all tastes for the
		   behavior of the <Enter> button. Now there is an option
		   that sets its behavior to traditional or HP-28-like.

2001/12/10 Calcoo 1.3.3 (for Debian GNU/Linux only)

	* Changed: RPN mode: behavior of the <Enter> button
	           Now it works like in most HP calculators. (In 1.3.2
		   it was set to work as in HP-28, which was not quite
		   standard).

	* Added:   keyboard shortcuts for parenthesis buttons
	
2001/12/3 Calcoo 1.3.2

	* Fixed:   RPN mode: behavior of the <Enter> button pressed
	           when the number has just been entered

	* Changed: now options and info/help have separate windows

	* Changed: code cleanups

	* Added:   engineering display format (the exponent is 
	           a multiple of 3)

	* Fixed:   incorrect behavior when "=" is pressed before all parens
		   are closed

	* Fixed:   adjacent opening parens are now possible

	* Fixed:   GtkErrors if the options applied are the same as the
	           current ones
	
	* Added:   "Help" tab in the info window

	* Changed: register X is not reset by changing the mode now
	
2001/11/19 Calcoo 1.3.1

	* Changed: body design, button arrangement

	* Fixed:   RPN mode: the bugfix of the previous version introduced
	           another bug - sometimes the stack was pushed twice.

	* Added:   displays for Y, Z, and T registers

	* Changed: the number of registers in RPN mode reduced from
	           infinity to 4 to comply with traditions

	* Changed: rearrangements in processing binary operations, digit
	           keys, and parentheses

	* Added:   more shortcuts
	
2001/11/16 Calcoo 1.3.0

	* Changed: body design, button arrangement

	* Fixed:   RPN mode: in earlier versions entering of a new number
	           did not push the stack. Thanks to Christian Weisgerber
	           for finding this bug.

	* Fixed:   PRN mode: in earlier versions recalling from the memory
	           did not push the stack.

	* Added:   a button to swap X and memory registers

	* Added:   another memory register
	
	* Added:   displays for memory

	* Changed: icons for memory buttons

	* Removed: optimization and other flags from configure.in
	
2001/11/13 Calcoo 1.2.4

	* Fixed:   a nasty bug introduced in version 1.2.2, which 
	           caused crashes when display was getting full

	* Changed: pixmaps for digit "1" (thanks to Daniel Richard G.) 

	* Added:   more keyboard shortcuts (thanks to Daniel Richard G.) 
	
2001/11/11 Calcoo 1.2.3

	* Added:   the state of RPN/Standard option is now saved in
	           $HOME/.calcoo, and is restored when calcoo is restarted

	* Added:   keyboard shortcuts for basic buttons

	* Added:   help tab in the info window

	* Changed: information about the current state of "enforced e
	           format" and deg/rad is now stored in "cpu"; as a 
	           result now it is affected by undo/redo

	* Fixed:   tan of 90 degrees now yields overflow instead of a large
	           number 

	* Fixed:   undo/redo in the previous versions did not affect memory -
	           now it does

	* Changed: code cleanups, rearrangements in the cpu structure

	* Changed: the icon for the RPN "Enter" button
	
	* Changed: now 0! yields 1 instead of overflow

	* Changed: defaults moved to default.h

	           expressions improved

	           is there is no fractional part
	
	* Changed: behavior of "copy": overflow message is now copied

	           format is enforced

	* Changed: evaluation of trigonometric functions tweaked to have 
	           cosine of 90 degrees equal to 0.0 rather than to 10e-17 
	           and so on

	* Added:   man page

	* Fixed:   bug in the evaluation of the factorial of large numbers
