Miss allChunks option in Release Notes and Migration instruction

[SanSan-]

Documentation Is:

Release Notes has no words about allChunks remove from options and what to do

• [ V] Missing
• [ V] Needed
• [ V] Confusing
• [ X] Not Sure?

Detail

I have no answer about migration from 0.12.0 to 2.x.x, cause latest version don't support allChunks options. SO didn't help too.

Your Proposal for Changes

Add to Release Notes or Documentation what to do with allChunks option in new versions.

[alexander-akait]

We don't have the allChunks option in our options for v0.12.0, we have many examples here in docs https://github.com/webpack-contrib/mini-css-extract-plugin, please clarify what you can't achieve

so, yes, i see. i think it is uncompatible with thread-loader in new versions, cause when they together

  module: {
    rules: [
       ...,
      {
        test: /\.scss$/,
        use: [          
          loaders.getCacheLoader(path.resolve(settings.cacheDir, 'css')),
          loaders.getThreadLoader('css'),
          MiniCssExtractPlugin.loader,
          'css-loader',
          'sass-loader'
        ]
      },
      ...
   },
   plugins: [
    ...,
    new MiniCssExtractPlugin({
      filename: `./css/[name].bundle${settings.resourcePrefix}.css`
    }),

following error is thrown

Module build failed (from ./node_modules/thread-loader/dist/cjs.js): Thread Loader (Worker 0) You forgot to add 'mini-css-extract-plugin' plugin (i.e. plugins new minicssextractplugin() )

it wasn't like this before, in 0.12.0
