pySᴇᴄDᴇᴄ is a computer tool to evaluate Feynman integrals and their weighted sums (amplitudes) using the method of sector decomposition and numerical integration. The new release of pySᴇᴄDᴇᴄ version 1.6 comes with a significant performance boost (3x–9x in common scenarios), and new features to make the evaluation and asymptotic expansion of amplitudes and integrals easier and faster. In this article we briefly review these features.
