💁‍♂️ My bad, thanks a ton for digging into it, @maxjacobson! I will make sure to add tests later, too.

Hey @localheinz thanks for looking into this!

Did some playing around in a php playground to confirm that this looks like it'll do the right thing: https://www.tehplayground.com/zbTW7R0p3HD408nB

Some real tests would be better but for now I'm satisfied :)

[localheinz]

Thank you, @maxjacobson!

Let's tag this, too, what do you think?

This will help at least all the folks who have required the latest version, or use the ^ operator (despite the fact that it is an unstable package)!

[maxjacobson]

@localheinz I'm open to it, but think we have some more work to do with our release process. Are you pulling in the test reporter at a specific tag when you use it? I sort of think everyone is just pulling in the latest master.

Some context: #54 isn't closed yet. #61 was merged, but we haven't perfectly adopted its recommendations - note that our releases don't include any downloads.

According to http://semver.org/#spec-item-4

Major version zero (0.y.z) is for initial development. Anything may change at any time. The public API should not be considered stable.

I never require unstable dependencies using the ^ or any other wildcard operators - I always pin to a concrete version.

Yup, good call. Tagging 0.4.2 today #102
