Some tests are probably out of date. Feel free to make a PR to fix those :)

[Semigradsky]

This error happens because browserslist defaults is dynamic. We should pass browsers option in tests.

I have fixed it in 2ca6df0

[Semigradsky]

@MoOx how about publish new version?
https://github.com/MoOx/postcss-cssnext/milestones/v2.11.0

[MoOx]

Yeah why not. Do you want me to cut a release from master? Not sure why you created a milestone with an issue that's look fixed in master.

[Semigradsky]

I just forgot to close issue.
