I guess this can jump directly to 0.15.1 now.

[vaga9938]

Okay, I'll check it out and make a PR based on the results. Wait for it.

[vaga9938]

I checked, it works fine.

[felipecrs]

@blakeblackshear, I think you can merge this one too.

[felipecrs]

@vaga9938 there are some conflicts to fix.

[vaga9938]

@felipecrs Fixed the conflict.

[felipecrs]

@vaga9938 please compare the config.yaml with the stable one, for example it's missing the authenticated web interface port mapping (but it may be missing more).

@blakeblackshear I think you should probably surrender the ownership of this variant and let someone else maintain it if they need.

I think none of us actually need or have a CPU to easily test this, and keeping such an old version around is probably worse than not.

Not to mention receiving support requests about it.

If you want, I can send a PR to remove it.
