DreamCalc 3 Pre-Release History

The following were pre-release versions of DreamCalc 3. DC3 was first released in March 2005.

DC3.0.19 Beta Public Release

Neon back-lit screen added to "Classic Metal" skin.
Several minor tweaks.

DC3.0.18 Beta Public Release

Function graphing data may now be exported as value lists.
Full User Guide added to the installation package.
Physical constant values have been updated to CODATA 2002 values.
Fixed bug where zero could not be entered into TVM registers.
Fixed RPN stack roll bug.
Fixed decimal point localization issue in graphing parser.
Fixed bug where setting read-only flag on data file caused settings to revert to default.
PRIMEQ function added to graphing parse list.
Tweaks to RPN mode.
Numerous tweaks, including changes to help menus.

DC3.0.17 Beta Public Release

Re-labeled some keys so as to be compatible with RPN. Actual RPN behavior has not changed.
Due to a request, the "Enhanced Graphics" option has been re-added (previously in DC2). Now called "Low Res Graphics".

Fixed minor bug involving paper roll and on-screen formula display where additional zeros could be shown with braces under certain circumstances.
Fixed minor bug where changes to the 'Anti-Alias Graphics' option did not persist between application launches. This option has been renamed to 'Enhance Graphics' in any case, as it now also controls high-lighting.

DreamCalc 1 Release History

DreamCalc 1 was first released in early 2003.

DC1.2.4

Modified behaviour of keys when using keyboard. Keyboard presses no long have an auto repeat effect and the behaviour of the [SHIFT] key has been subtly modified so that you can hold it down while pressing other keys.
The View Paper Roll F12 option now toggles the Paper Roll Window. Additionally, the main window now retains active focus when the Paper Roll Window is shown.
Fixed bug where the [+/-] button in the Simple Calculator view wrongly operated back space. Don't know how I missed this one.
Some minor changes and updates.

DC1.2.3

New 'RCL/STO' key added to facilitate multiple memory storage. DreamCalc can now store 16 variable values, in addition to the independent 'Min/MR' functions. To implement this, the back space key has been moved to the numeric keypad, and the 'Cancel' button, which was of limited use, is no-longer present.
Fixed bug where erroneous results were given when the calculator was placed in scientific precision AND engineering mode at the same time.
Fixed bug where pressing CTRL-C in the Paper Roll Window copied the current value displayed in the calculator's LCD display, rather than the selected paper roll text.
Fixed 'bug' where on some systems, DreamCalc reported 'RichEdit line insertion error'. This was due to the fact that Microsoft seems to have broken backward compatibility in a crucial DLL update. Modified DreamCalc so it does not use the affected DLL.
Fixed bug where pressing 'E' on the keyboard while in hex base-n mode actually operated the 'EXP' key, rather than appending the value 'E' to the display.
Some minor changes and updates.

DC1.2.2

Fixed bug affecting copy & paste functions. Previously, DreamCalc only recognised the decimal point '.' symbol as a decimal separator. When copying and pasting, DreamCalc now uses the decimal separator symbol specified in the user's regional settings under Windows.
Added new high contrast skin to improve accessibility.

DC1.2.1

Fixed bug where the 10^x function gave an erroneous result when x contained a decimal value, rather than an integer.
Modified main window re-sizing code so that DreamCalc runs under WINE for Linux.
Introduced patch version number, so that full version number is of form major.minor.patch.

DC1.2

First public release.

DC1.1 Beta Release

Beta release.

DC1.0 Alpha Release

Alpha release.
