Changed: upgrade to PostCSS 6

All postcss plugins dependencies have been updated to latest version to ensure full PostCSS 6 compatibility.

Some breaking (minor) changes:

image-set polyfill change 2x from 144dpi to 192dpi
whitespace changes for image-set polyfill output
rebeccapurpule is now an hexa number
custom-selector does not output useless (empty) blocks with a selector with no rules associated

You can expect some other since all postcss plugins used have been updated to latest versions. If you have unexpected regression, please check corresponding plugins changelog before opening an issue.

Added: warning is emitted is you use custom property sets and `@apply`

This feature won't be included in next the major release of postcss-cssnext.

This most likely won't get any more support from browser vendors as the spec is yet considered deprecated and alternative solutions are being discussed. Read more about the reason here https://github.com/pascalduez/postcss-apply

In order to fix this, here is a warning. You are welcome. Read more about this issue

0.4.0 - 2014-10-23

Changed: color feature has been exploded to multiples features (#40).

Before

var output = cssnext(input, {
  features: {
    // providing `true` (or omitting this value) instead of the following object
    //  was the default behavior
    color: {
      color: true
      hexAlpha: true
      hwb: true
      rebeccapurple: true
    }
  }
})

Now

var output = cssnext(input, {
  // as usual if you where using all features, you can just omit this values
  features: {
    colorFunction: true,
    colorHexAlpha: true,
    colorHwb: true,
    colorRebeccapurple: true
    }
  }
})

Changed: cssnext options are not passed to all plugins anymore. You know need to specify feature options by passing object to features properties
(#39).

Before

//eg: preserve custom properties
var output = cssnext(input, {
  preserve: true
})

Now

//eg: preserve custom properties
var output = cssnext(input, {
  features: {
    customProperties: {
      preserve: true
    }
  }
})

Added: more control on sourcemap is possible using the new map option (direct postcss option). Using this option make sourcemap one to be ignored and change the return value of cssnext() (object instead of string)

This change have been made to avoid collision between options (of each features).
