I am continuously getting these warnings in my code:
```julia
LB = Array{candidateKeypoint,1}(0)
H̄ = Array{Any}(3,3)
for extremum in LA′
α1Star = 0.0
α2Star = 0.0
α3Star = 0.0
σ = 0.0
x = 0.0
y = 0.0
ω = 0.0
for i = 1:5
H̄ = Hessian(extremum.o, extremum.s, extremum.m, extremum.n)
ḡ = ThreeDgradient(extremum.o, extremum.s, extremum.m, extremum.n)
αStar = alphaStar(H̄, ḡ)
ω = omega(H̄, ḡ, extremum.o, extremum.s, extremum.m, extremum.n)[1]
δOE = δMin * 2^(extremum.o - 1)
α1Star = αStar[1]
α2Star = αStar[2]
α3Star = αStar[3]
σ = (δOE/δMin) * σMin * 2^((α1Star + extremum.s)/nSpo)
x = δOE * (α2Star + extremum.m)
y = δOE * (α2Star + extremum.n)
extremum.s, extremum.m, extremum.n = round(Int64, extremum.s + α1Star), round(Int64, extremum.m + α2Star), round(Int64, extremum.n + α3Star)
if max(abs(α1Star), abs(α2Star), abs(α3Star)) < 0.6 || extremum.s < 1 || extremum.s > 3
break
end
end
if max(abs(α1Star), abs(α2Star), abs(α3Star)) < 0.6 && extremum.s > 0 && extremum.s < 4
push!(LB, candidateKeypoint(extremum.o, extremum.s, extremum.m, extremum.n, extremum.intensity, σ, x, y, ω))
end
end
```

Any suggestions please?

You mean in addition to the suggestion that follows `WARNING` above the stacktrace?

HI @Tamas_Papp! Thanks for the reply.
Hence the doubt.

It may be that a dependency has not updated their deprecation warnings. Three lines down from `WARNING` it even tells you which:

Since you’re on Julia 0.6.4 on JuliaPro and ColorTypes presumably has been on 0.7 for [quite some time](https://github.com/JuliaGraphics/ColorTypes.jl) now, there’s really nothing to do here. Maybe upgrade JuliaPro once it’s released for 0.7/1.0.
