  In this work we report on a new version of FeynCalc, a Mathematica package
widely used in the particle physics community for manipulating quantum field
theoretical expressions and calculating Feynman diagrams. Highlights of the new
version include greatly improved capabilities for doing multiloop calculations,
including topology identification and minimization, optimized tensor reduction,
rewriting of scalar products in terms of inverse denominators, detection of
equivalent or scaleless loop integrals, derivation of Symanzik polynomials,
Feynman parametric as well as graph representation for master integrals and
initial support for handling differential equations and iterated integrals. In
addition to that, the new release also features completely rewritten routines
for color algebra simplifications, inclusion of symmetry relations between
arguments of Passarino--Veltman functions, tools for determining matching
coefficients and quantifying the agreement between numerical results, improved
export to LaTeX and first steps towards a better support of calculations
involving light-cone vectors.
