Release notes 

Finished and cleaned up the polynomial factoring and polynomial division C code, so polynomial operations give better results and are 30 times faster in some cases. The "simplify quick" option gives much better results now, sometimes better than any other simplify option. The coloring scheme was improved: all prompt and normal text is now the terminal emulator's default color for text (usually uncolored); expressions remain colored if color mode is enabled. m4 Mathomatic can now easily be made to work under BSD Unix.

Changelog 

View the full changelog

Many tweaks and corrections to simplification and polynomial operations were made.

4/21/11 - Created m4 Mathomatic input file "tests/trig". Lists all trig and
          hypertrig functions, allowing testing of their simplification
          and manipulation.

4/22/11 - Sped up polynomial operations to be another 30 times faster
          in some cases. Finished and cleaned up the polynomial factoring
          and division C code. Thanks again to Kingsley G. Morse Jr. for
          showing me this needed to be done.

          The "simplify quick" command was changed to not combine unlike
          denominators, making it much more useful, doing better
          simplification than any other simplify option sometimes.

4/23/11 - The tally command now returns the ending total and sets it as the
          current equation.

          Fixed an old bug just discovered today where expressions like
          (x - y)*(x^99 - y^99) were being factored into something huge
          with the simplify and fraction commands, which are the only
          commands that do polynomial factoring.

          Improved coloring scheme: all prompt and normal text is now the
          terminal emulator's default color for text (usually uncolored).
          Expressions remain colored if color mode is enabled. Thanks to
          Carl U. Grayser for the good idea.

4/26/11 - Improved the fraction command by factoring polynomials first.
          Specifying the "numerator" and "denominator" options together
          will make the fraction command return with failure if the result
          is not a fraction, otherwise the entire fraction is returned.

          Allow setting "M4" makefile variable to "gm4" (GNU m4), so that
          m4 Mathomatic can work under BSD Unix after installation.
          Be sure to use gmake to compile Mathomatic under BSD Unix;
          Non-GNU Unix make and Unix m4 do not work with Mathomatic.
