With the development on canonical differential equation, new algorithms for generating short IBP systems, the era of analytic computations of multi-loop multi-leg and multi-scale Feynman integrals is coming. We analytically computed all 2-loop 6-point planar massless Feynman integrals, and also computed all 3-loop 5-point planar massless Feynman integrals. Those examples represent the state-of-the-art Feynman integral computations and will in future provide precision physics input for the LHC and the next generation of colliders.
