The latest version of this license is in http://www.latex-project.org/lppl.txt %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Version 5.2 of diffcoeff initializes two variables that other- wise can conflict with other packages and improves handling of an empty differentiation variable argument. There are some small additions to the documentation. 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.
