Fix CuArray compatibility with NNlib

[maleadt]

ref JuliaGPU/CuArrays.jl@da7107b
fix JuliaGPU/CuArrays.jl#327

OT: what does the -0 mean? CuArrays 1-1.0.1 just has NNlib = "0.5".

It should be:

OT: what does the -0 mean

Compatible up to 1.0 (exclusive)

NNlib = "0.5".

Compatible 0.5 - 0.6 (exclusive). This is "semver notation" for pre 1.0.

[maleadt]

This is "semver notation" for pre 1.0.

Right; then why did JuliaRegistrator convert the NNlib = "0.5, 0.6" compatibility line in Project.toml to a non semver-compatible 0.5-0? I had expected it to be just 0.5-0.6 is why I was confused by the -0.

There was some normalization that ran but I thought that was a one time thing. This looks wrong, yes. cc @StefanKarpinski

Because when I wanted to follow semver strictly, people didn't like that it would require people to change their version bounds when new 0.x versions were released. So for now normalization is done considering all 0.x versions to be compatible. Unless there's a 0.7 version to be incompatible with, 0.5-0.6 is equivalent to 0.5-0.

Is this good to go? Users are running into this.
