[ChrisHines]

See commit messages for details.

There are more dependencies that we could upgrade, but I only upgraded github.com/go-kit/log so far. Here's the list of possible upgrades at this moment:

Should we bump any of these?

LGTM

Let's update the rest of the libraries before tagging 0.12. I can take care of that if you want me to.

[ChrisHines]

It's easy enough for me to do it. I'll add another commit here soon.

[ChrisHines]

Well, now the race detector is failing github.com/go-kit/kit/sd/eureka integration tests. It may not be related to the dependency upgrades, though. The race seems to be between something in the sd/eureka package and something in the github.com/hudl/fargo package and as far as I can tell the last commit didn't upgrade github.com/hudl/fargo or any of its dependencies.

Thoughts?

[sagikazarmark]

The eureka tests are flaky. Haven't been able to figure out why, but then again, it'll probably be deprecated and removed at some point.

Just for the record this pulls the latest patch release for each minor, which is what we wan't but wasn't obvious to me.

[ChrisHines]

Yes. I double checked the logs to make sure it did that because I wasn't sure either.

[sagikazarmark]

This PR was the last item in the v0.12.0 milestone. Is there anything else we want to do before a new release?

[ChrisHines]

I don't have anything else.
