Changes since 14.3.6:
- Perfected the user interface for the sum, product, and integrate
commands.
- Restored initial full simplify in the limit command for better
results, that was unintentionally removed in version 14.1.0.
- Fixed an endless loop in simplification; results look better, too.
- Added "set save" command, which makes all current session options
permanent, by saving them in "~/.mathomaticrc". "set no save"
removes this file.
- Added "mathomatic -s" option, which stands for secure mode. This is
a run-time option that disallows shelling out and writing files, and
was created for use on public servers that can't use the SECURE
compile-time define.
- Doubled the default maximum mathematical expression size to allow
larger expressions.
- A fatal compilation error when compiling with defines other than
UNIX was fixed.
- Slight improvement made to simplification; results are more simple
and stable.
- The maximum integer that can be factored has been raised from 14 to
15 decimal digits.
- Small fix made to fraction command and "simplify fraction" for
better looking fractions.
- Added a "simplify quickest" command option, which does no
unfactoring nor factoring.
- Made full simplification more efficient and simpler by cutting out
unnecessary loops.
- Improved the divide command and enabled its use in the symbolic math
library. Enabled code and variables commands in library, too.
Currently, library output of these 3 commands can only be gathered
by redirecting to a file.
- Added "set autoselect" and "set auto" options. Use "set no auto" to
always store entered expressions into equation spaces, unless it is
a command.
Changes since 14.2.7:
12/23/08 - Simplified makefile.
12/26/08 - Fixed rules for simplifying "(x^n)^m" so "misc/john.in" and
others simplify better. Works similar to Maxima now.
12/27/08 - Numeric GCD now properly returns the other parameter, if
either parameter is 0. Renamed "misc/polyroots.c" to
"misc/roots.c" and simplified this example code.
12/30/08 - Added "update" script, which updates the function
prototypes in "cproto.h".
1/1/09 - Optionally factor out the gcd of integer coefficients when
improving readability, for example: 6x+4y becomes 2*((3*x) +
(2*y)). This is now the default.
1/13/09 - Added descriptions of all interesting math scripts in
"tests/README.txt".
1/16/09 - Allow nintegrate and "integrate definite" commands in the
symbolic math library; the bounds are specified in the two
equation spaces following the current equation.
1/18/09 - Made expression and equation entry always consecutively
numbered equation spaces, unless memory is exhausted.
1/19/09 - Made consistent list command output with only one newline
after each equation space.
1/21/09 - Fixed erroneous doubling of parentheses display when solving
and showing steps with "set debug 2".
1/22/09 - Added -b option, to conveniently set bold color mode from
the command line.
1/25/09 - Improved looks of eliminate command by not solving if
equation is already solved.
2/3/09 - Table of contents was added to the Mathomatic User's Manual.
2/5/09 - Added display of any numerical fractions when calculating or
using calculate command; for example, entering "1/2+3/8" now
results in "answer = 0.875 = 7/8".
2/6/09 - Removed erroneous lsqrt() routine obtained from Wikipedia, so
that matho-sumsq works properly now.
2/7/09 - Disable pause command when appropriate (when input not a tty
and for symbolic math library).
2/8/09 - Polished up educational example scripts in "tests" directory.
2/11/09 - Entry of a function now results in "Named functions
currently not implemented" error message.
2/12/09 - Bugfix to matho-primes and added "misc/limits.c".
2/15/09 - The fraction command was fixed to give better results. "set
display2d" flag now no longer affects any results at all, it
only affects 2D output mode.
2/17/09 - Renamed -h (HTML) option to -x, -h is now the help option.
Added -w option to set wide output mode.
3/9/09 - Found the correct formulas for solving the general cubic
equation on Wikipedia, so "tests/cubic.in" always gives
correct answers now.
3/12/09 - Tweak made to simplify result beautifier: factoring priority
only given to real variables now, special constant variables
pi#, e#, and i# have no effect and behave like any constant
now.
3/15/09 - Corrected and improved parse_complex() C function for more
complex number functionality and a bug fix.
3/18/09 - Added "set negate_highest_precedence" option, which allows
the negate operator to be the lower precedence of times and
divide, like it is in Maxima and most other math programs.
3/24/09 - Made "set no autosolve" mode more useful by making it solve
if a solve variable is entered with an equals sign. This
allows easy entry of both single variable expressions (with
no =) and solve variables (with =) while in this mode.
3/27/09 - Selecting equations by entering the equation number was
returning with error if the equation space was empty.
Fixed, you can now select any previously allocated equation
space.
Changes since 12.7.7:
10/10/07 - Proper error reporting for shelling out (! command).
10/12/07 - Created directory "m4" to play with using m4 to allow easily
entering functions through macros.
10/14/07 - Improved "set dir" to display the new current directory and to
default to the home directory.
10/17/07 - Entering "=" by itself now swaps equation sides instead of doing
nothing.
10/18/07 - New "mathomatic.ico" file with transparent background.
10/21/07 - Increased speed of taylor command up to 3 times by not doing an
unnecessary simplification.
Added "tests/distance.in".
10/22/07 - Fixed a small problem in calculate command, allowing instant
calculation of (2+2i)^99 now.
Entering any power of any complex number should work now.
10/29/07 - Solving now reports what degree polynomial the equation is.
11/12/07 - Fixed 3 bugs in optimize command.
11/16/07 - Fixed another bug in optimize command.

icon files for Linux.

command.
Allow upper case when parsing infinity constant name "inf", required by CygWin
version and maybe others.
The makefiles no longer strip the created executables.
Reordered source code so many functions can be defined returning "void" (which
means no return value).
Added "tests/how_limit_works.in" tutorial and restored "doc/notes.html".
Testing change to only one kind of partial unfactoring (partial_flag =
true/false, default true), completely distinct from full unfactoring. Used
throughout, let me know if this breaks anything.
Added "simplify fraction" option, which simplifies like Maxima's ratsimp().
Changes:
- Remove GPL preamble in "primes/*.c", so everything is LGPL.
- Allow entering "e#" and "i#" as "e" and "i". Display "e", "i", and "pi" as
"e#", "i#", and "pi#".

confused with commands. This is a bug fix.

Added to obsolete.mk checking for IGNORE_RECOMMENDED.
I did not manually go through and fix any aesthetic tab/spacing issues.
I have tested the above patch on DragonFly building and packaging
subversion and pkglint and their many dependencies.
I have also tested USE_ABI_DEPENDS=no on my NetBSD workstation (where I
have used IGNORE_RECOMMENDED for a long time). I have been an active user
of IGNORE_RECOMMENDED since it was available.
As suggested, I removed the documentation sentences suggesting bumping for
"security" issues.
As discussed on tech-pkg.
I will commit to revbump, pkglint, pkg_install, createbuildlink separately.
Note that if you use wip, it will fail! I will commit to pkgsrc-wip
later (within day).
