Strange warning on PyPlot for 1.7.0 "vendor() is depreciated ..."

I’m using 1.7.0 on my Intel machines now with the MKL Blas and happily avoiding the OpenBlas problem. I got this message from PyPlot the first time I call it from 1.7.0 in a new REPL session but not for calls
after that

┌ Warning: `vendor()` is deprecated, use `BLAS.get_config()` and inspect the output instead
│   caller = npyinitialize() at numpy.jl:67
└ @ PyCall ~/.julia/packages/PyCall/3fwVL/src/numpy.jl

Is this anything to take seriously? PyPlot seems to be working fine.

Thanks, seems a solution is in the works.
