Just move to grunt-postcss, because it is more official way to use Autoprefixer.

[joseluisq]

@ai Great! So this case I think you may to add to README.md some explaination about this and the official link to grunt-postcss.

[ai]

@joseluisq Autoprefixer’s README.md has link only for grunt-postcss ;).

[joseluisq]

@ai sure
In general, do you recommend to use grunt-postcss instead grunt-autoprefixer right?
If It's true, Is grunt-autoprefixer deprecated?

[ai]

@joseluisq yeap, I recommends grunt-postcss.

But I can’t deprecate grunt-autoprefixer beause it is not my project.

[joseluisq]

@ai I understand now I will refer to grunt-postcss for official way.
Thanks 👍

@nDmitry this issue is not closed yeat, because you didn’t display result.warnings().

BTW, PostCSS Runner Guidelines is highly recommended for Autoprefixers plugins too.

[nDmitry]

@ai do you think I should deprecate this plugin in favour of grunt-postcss?

[ai]

@nDmitry Yeap, grunt-postcss updates faster and it is better for ecosystem. And you need to maintain only one project.

[nDmitry]

@ai so be it)

[nDmitry]

Ok, guidelines are passed too.
