[Bug] is it a break change v5.0.5?

[SoloJiang]

Before this version, the plugin works well with webpack4, but now it updated postcss to v
8 which only can work with webpack5. The change has maked our projects build failed.

Why is postcss not compatible with webpack5?
Our unit tests seem to be all green with webpack4.

It can however be a node.js version. What version are you on?

I have the same issue @NMFR, I am running node 12.22.1 and npm 6.14.12

This is a breaking dependency and it is actually breaking the default install of the Phoenix Framework

Should be fixed in 5.0.6.

Released:

• 5.0.6 with a revert of the cssnano and postcss major upgrade.
• 6.0.0 with the cssnano and postcss major upgrade.

Reopen if there are still problems on 5.0.6 please.
