SmeftFR v3 [Comput.Phys.Commun. 294 (2024) 108943, 2302.01353, https://www.fuw.edu.pl/smeft/] is a publicly available code that enables derivation of Feynman rules for interaction vertices from the dimension-5, dimension-6, and (so far) all bosonic dimension-8 SMEFT operators. Obtained Feynman rules allow for consistent numerical (e.g. in MadGraph) or symbolic (e.g. in FeynArts, FeynCalc, FormCalc) calculations in SMEFT to the 1/Λ^4 order in the EFT expansion, including dimension-6 squared and dimension-8 terms, which is a novelty in the literature. In my talk, I will discuss some of the most important new features of SmeftFR v3, such as choosing among and using one of the predetermined input schemes, including one for the CKM matrix. I will also provide practical examples of usage of the code and describe some of its possible applications.
