Yes.

This code becomes between a factor 40 and 100 slower moving from 0.6.4 to 0.7:

using StaticArrays

u = @SVector [1.0, 0.0, 0.0]
v = @SVector [0.0, 1.0, 0.0]

function _normals(tangents, ::Type{Val{1}})
    PT = eltype(tangents)
    D  = length(tangents)
    T  = eltype(PT)

    n = zeros(T,D+1)
    b = Array{T}(D,D)

    for i in 1:D+1
        fill!(b, zero(T))
        for j in 1:D
            for k in 1:i-1
                b[k,j] = tangents[j][k]
            end
            for k in i:D
                b[k,j] = tangents[j][k+1]
            end
        end
        n[i] = (-1)^(i-1) * det(b)
    end

    n *= (-1)^D / norm(n)
    normals = SVector{1,PT}([PT(n)])

    metric = T[dot(tangents[i], tangents[j]) for i in 1:D, j in 1:D]
    volume = sqrt(abs(det(metric))) /  D

    return normals, volume

end

ts = @SVector [u,v]

_normals(ts, Val{1})
@time _normals(ts, Val{1})
