KALKULATOR - VERSION HISTORY
============================

VERSION 1.48 - 97/01/31

   Changes in physical constants: new values added, some of the
   old ones corrected or revised.

VERSION 1.47 - 97/01/02

   The two missing pixels at the bottom of the Display Line
   have been restored (16-bit version only).

   Font files reverted from .FNT to .FON standard to avoid
   problems in the 16-bit version.

VERSION 1.45 - 96/12/26

   A Result Variable can be now assigned to every expression;
   this makes chained calculations easier.

   The Expression Line now stays highlighted after an expression
   has been evaluated; its contents will be erased after any new
   input.

   Introduced a simpler method to add a regression line to an
   existing graph canvas.

   The graph Undo button now works as a toggle.

   The tabbed control widgets in the Main Panel have been
   reworked (somewhat different look and feel).

   The program will now find the fonts even if the working
   directory is not set to the program directory.

VERSION 1.42 - 96/11/20

   A new feature: simultaneous function graphs of any combination
   of expression lines, with joint min/max evaluation.

   The Main Panel buttons (and some others) have been replaced
   with a different button type, using significantly less of
   Windows' resources (especially important for Win 3.1 users).

   General cleanup of the help file.

   New update and upgrade policy: all free for the lifetime of
   the program, without version limit.

VERSION 1.40 - 96/11/05

   A major new feature: computer math operations, including
   conversions between binary, octal, hex and decimal, also
   8, 16 and 32-bit word lengths.

   The Linear Algebra and Polynomial Root panels are now called
   from the new Extras menu (their buttons are no longer in the
   Bottom Line).

   For users whose email programs have problems handling file
   attachements: Kalkulator will now create a registration key
   file when you enter your key code obtained in email (in mail,
   by phone, etc.)

   The missing exponent in the Boltzmann constant has been added.

VERSION 1.31 - 96/08/29

   A bug fix: no more locking when a data buffer is sorted while
   scrolled down (16-bit version only).

   The default directory for statistical and linear algebra files
   is now always set to the Kalkulator home directory, which could
   not be the case if the program was executed from a third-party
   shell (registered copies only).

   New topics in the HOWTO.TXT file.

VERSION 1.30 - 96/07/15

   Problem with saving multiple .kal files has been fixed.

VERSION 1.29 - 96/06/23

   There is now an option to keep Kalkulator window on top in the
   Mini Layout mode.

   The Escape key no longer closes the graph panel; use Enter.

   A check has been added against too narrow plot limits.

   A bug occuring in data point insert operation in the XY mode
   has been fixed.

VERSION 1.28 - 96/06/12

   The definition of harmonic average has been corrected.
   Small touch-ups in the program and in its Help file.

VERSION 1.27 - 96/05/29

   Fixed problem (?) with screen fonts on some systems.

   Small changes in how Data Grids handle errors in user input.

   New ordering information in the Help file: HOW TO REGISTER
   BY PHONE, FAX OR ON THE WEB USING A CREDIT CARD.

VERSION 1.25 - 96/05/14

   An autoscroll option has been added: the Expression line
   will scroll to the next expression slot upon a successful
   computation.

   A [Clear] button has been added to the Root Panel.

VERSION 1.24 - 96/04/22

   A new feature: finding real and complex roots of polynomial
   equations with real coefficients (linear, square, cubic;
   also quartic in the registered version).

   Pressing the F1 key will now bring context-sensitive help in
   most of the dialog boxes.

VERSION 1.23 - 96/03/31

   A bug, introduced in V1.21 has been fixed: Kalkulator no
   longer refuses to do sums and derivatives.

VERSION 1.21 - 96/03/18

   32-bit: first release for Windows/95
   16-bit: brought in sync with the 32-bit version

VERSION 1.20 - 96/03/12

   A major new feature: linear algebra operations (matrix and
   vector algebra, matrix inversion, systems of simultaneous
   linear equations).

   The editor for data buffer has been redesigned: now it uses
   a data grid.

   The maximum length of an expression has been increased to
   72 operands/operators or 120 characters (registered copies).

   The reciprocal function has been renamed from inv to rcp.

   A bug fix: no more lockups when the user attempts to perform
   column-wise data buffer computation if arithmetic errors
   occur at some of the points.

VERSION 1.10 - 96/02/12

   A maintenance release (despite round version number). Fixed bug
   causing non-rounded display of some values describing plots in
   log scale.

VERSION 1.09 - 96/01/14

   Sound effects added.

   Important ONLY for some European users: a "." is now used as
   the decimal point, regardless of regional settings.

VERSION 1.07 - 95/12/14

   Expressions, not just values, are accepted wherever numerical
   input is expected. A "Mini Layout" option introduced. Physical
   constants added.

VERSION 1.04 - 95/11/25

   Workaround around a compiler bug, affecting user functions.

VERSION 1.00 - 95/11/11

   The original release.
