@jamesscholeyweb cssnext uses old postcss api. U can install gulp-postcss5 and use postcss4 compatible versions of the other plugins.

@TrySound Thanks Bogdan, am I right in thinking that cssnext is just a collection of postcss plugins? I could achieve the same result bringing in the plugins I require alone?

[TrySound]

@jamesscholeyweb You are right. But if not all plugins use new api you will get some deprecation warnings. Errored was only postcss-import, I think.

@TrySound Well latest postcss-import works fine with the 5.0 api, so I'll just build in what I require. What I don't understand is if cssnext is just a collection of modules to accompany postcss why they don't just pull in the latest versions on install? Anyway I have it working as I require with latest version of postcss and import. Thanks Bogdan
