Dependency	postcss-cssnext
Current Version	2.11.0
Type	devDependency

The version 3.0.0 is not covered by your current version range.

Without accepting this pull request your project will work just like it did before. There might be a bunch of new features, fixes and perf improvements that the maintainers worked on for you though.

I recommend you look into these changes and try to get onto the latest version of postcss-cssnext. Given that you have a decent test suite, a passing build is a strong indicator that you can take advantage of these changes by merging the proposed change into your project. Otherwise this branch is a great starting point for you to work on the update.

Release Notes

3.0.0

Removed: support for node 0.12

Node 4+ is supported.

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.
