- Fixed bug in error reporting that made error messages appear several times.
- Added evaluation time display, if evaluation takes more than one second
- Added NumIntegrate(Expr,Variable,Start,Stop) function as wrapper for ROMBERG

Pre16:
- Fixed bug in IF-THEN-ELSE display
- Added function NumDiff(Expr,Var,Value) for numerical derivative into `Numerical' feature.

Pre17:
- Fixed brackets for MDEFINE (:=)
- Fixed bug in error handling: Error was not shown, when previous command was not displayed
- Fixed bug concerning modification of subexpressions (for example SELECTION feature): Modifying more than one expression at a time produced wrong results.
- Added functions for handling data lists in the form [[x0,y0],[x1,y1],...] ("Tables"). Those are included in the 'Numerical' feature. Function name: TableOpApply(Table1, Table2,..., function(x,y1,y2,...)). See Palette for demos.
- Added syntax highlighting for known expressions. The keywords were taken from the Emacs Maxima mode.
