PHI-1.3 released

I’m please to announce a new version of PHI – distributed with FeynCalc-4.1.1.

PHI adds tools to FeynCalc for manipulating covariant derivatives etc. of effective theories like Chiral Perturbation Theory. Moreover, PHI provides an alternative way of creating coupling definitions for FeynArts – convenient for generating a large number of Feynman rules from different Lagrangians.

This is mostly a bug fix and maintenance release.

For a full list of changes, see the read-me file and the change-log.
