[Pkg-javascript-devel] node-postcss 7.x -> 8.x transition - work started in experimental

[Pirate Praveen]

Hi,

I have uploaded node-postcss 8.0.5-1 to experimental.

autopkgtests for node-css-loader, node-postcss-filter-plugins, 
node-postcss-minify-font-values, node-postcss-modules-extract-imports, 
node-postcss-modules-values, node-postcss-reporter failed with this 
error

pkg-js-autopkgtest-require FAIL stderr: postcss.plugin was deprecated. 
Migration guide:

and rainloop rebuild failed with
