v3.0.0

This release upgrades PostCSS to version 8 which results in better performance and enable further optimization in future. As it's now a peer dependency it might be a breaking change because you've to install it yourself now if you're not using npm >= v7. Apart from that all deprecations are removed now, meaning they are not throwing a warning anymore.
