The latest version of this license is in http://www.latex-project.org/lppl.txt %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Version 5.3 of diffcoeff fixes a bug that arose in the use of the differential in beamer, introduces an alternative way of specifying orders of differentiation and reintroduces the override option. Version 5.0 of diffcoeff introduced many interface incompat- ibilities with version 4, which is still available through the trailing optional argument in the \usepackage statement, e.g., \usepackage{diffcoeff}[=v4] Version 5 requires xtemplate from the l3packages bundle and the mleftright package.

## diffcoeff – Write differential coefficients easily and consistently

This package allows the easy and consistent writing of ordinary, partial and other derivatives of arbitrary (algebraic or numeric) order. For mixed partial derivatives, the total order of differentiation is calculated by the package. Optional arguments allow specification of points of evaluation (ordinary derivatives), or variables held constant (partial derivatives), and the placement of the differentiand (numerator or appended).

The package is built on xtemplate and the configurability it enables, extending to differentials (including simple line elements) and jacobians.
