Does Flux support N-dimensional convolutions, where N>3?

While this works:

Conv((1,1,1), 1=>1)(rand(1,1,1,1,1)) #3D convolution

This throws an error:

Conv((1,1,1,1), 1=>1)(rand(1,1,1,1,1,1)) #4D convolution
#ERROR: MethodError: no method matching conv!(::Array{Float64,6}, ::Array{Float64,6}, ::Array{Float64,6}; pad=(0, 0, 0, 0), stride=(1, 1, 1, 1), dilation=(1, 1, 1, 1))
