Precision tests of the unitary of the CKM matrix is an active area in the search for new physics. The desire for additional determinations of the matrix element |Vub| and a long-standing 2-3σ discrepancy between results from inclusive B→Xu and exclusive B→π processes motivate the study of QCD B→π semi-leptonic form factors on the lattice. The status of our preliminary B→πlν results will be discussed by highlighting updates to our analysis. The final results of this project will provide updates to the 2015 RBC/UKQCD B→πlν result.
