Update from the BIPM watt balance

This paper reports the latest progress made on the BIPM watt balance project. The type A uncertainty of the Planck constant measurements was reduced from 1.4 parts in 10⁶ to about 5 parts in 10⁷. The new magnet was successively fabricated and assembled with an expected high uniformity of the flux density of several parts in 10⁴. Several new components are being introduced into the apparatus which we expect to reduce the type B measurement uncertainty significantly.
