maybe I'm not in the right place writing. But the situation is that after migration to Webpack 4 I had to change the style extractor to mini-css-extract-plugin from extract-text-webpack-plugin. From now on hashing began not to work properly: if I change styles, the hash of entry scripts changes, but if I change scripts, the hash of styles does not change.

I use the same settings as I did with webpack 3. Then I studied the problem length and breadth. Solving is simple:

output: {
        filename: '[name].[chunkhash].js'
},
plugins: [
        new webpack.HashedModuleIdsPlugin(),
        new ExtractCSS({
            filename: '[name].[contenthash].css'
        })
]

+ extract runtime chunk aka manifest

But now I dont have any glue.
I'm just created repo with this issue: https://github.com/mishelen/reproduce_hash_invalidation webpack settings are in config folder
