Version 1.1 (November 2026) adds the tests of the method on the six autonomous problems of the FDE-testset (Brugnano, Gurioli, Iavernaro, Vikerpuur, Fractal Fract. 9 (2025) 312; Section 6.5 of the revised article): code/pi_solver.py, code/fde_testset_problems.py, code/17_fde_testset.py and data/part10_testset.json, and code/print_figures.py, which redraws all figures in the final print style.
