Changes introduced in this version are organized by these topics:

The third output argument of the solver fminimax, maxfval, is described in the documentation as the maximum of the objective functions in the input fun evaluated at the solution x, that is, max(fval). Before this release, fminimax actually returned the maximum of the objective functions in the reformulated minimax problem internally constructed by the algorithm. This value was typically very close to, but not necessarily equal to, max(fval). fminimax now returns the exact value of max(fval) in the output maxfval.
The iterative display for fminimax includes a new column with header Objective value that reports the objective function value of the nonlinear programming reformulation of the minimax problem. The column header Max{F,constraints} has been changed to Max constraint, and the column now contains the maximum violation among all constraints, both internally constructed and user-provided.
The iterative display for fgoalattain now shows the value of the attainment factor in the Attainment factor column. A new column, Max constraint, contains the maximum violation among all constraints, both internally constructed and user-provided.
