The latest test of LFU in RK and RK from LHCb e-Print: 2212.09153 [hep-ex] quote the individual BRs of B->K(*)ee and B->K(*)mumu in the q2 bin [1.1-6]. The new RK() measurements quoted in this paper are included in the flavio. However, we added the individual BRs.

New measurement of B+->K+nunu branching fraction was published recently in 2023 e-Print: 2311.14647 [hep-ex] by Belle II. This is the first ever signal observed by Belle II consisting of di-neutrino in the final state. In the same paper the world average of B+->K+nunu branching fraction is also mentioned. We added both the details in the flavio.
