MaxLoop is intended to provide symbolic tools for calculations involving = scattering amplitudes and loop diagrams while remaining entirely within = the Maxima environment. Its current capabilities include: - Lorentz indices, metrics, vectors, and tensor contractions; - scalar products and kinematic substitutions; - noncommutative Dirac chains; - Dirac traces and spinor completeness relations; - polarization sums; - utilities for constructing and simplifying squared amplitudes; - dimensional-regularization expressions and extraction of UV poles and = finite parts; - symbolic infrastructure for Passarino=E2=80=93Veltman functions; - analytic and numerical support for selected (A_0), (B_0), and (C_0) = configurations. The current version of MaxLoop is not (yet) a complete replacement of = FeynCalc or Project X (the standard packages in the area) but it is a = first step in this direction. The repository includes a user guide, examples, regression tests, and = separate smoke, standard, and full-audit test suites. MaxLoop is free software distributed under the GNU General Public = License, version 2 or, at your option, any later version = (GPL-2.0-or-later). This is a first public release, and several parts of the package are = still under active development. In particular, general tensor reduction, = arbitrary-mass (C_0) functions, (D_0) functions, automated diagram = generation, and complete renormalized one-loop workflows are not yet = fully implemented. Comments, bug reports, suggestions concerning Maxima programming = practices, and contributions would be very welcome. Issues may be = reported through the GitLab repository. I would also be grateful for any advice regarding the possible inclusion = or listing of MaxLoop among external packages developed for Maxima. Best regards, Prof. Alfonso R.
