Drop support for webpack 4 and node <= 10 - For older webpack or node versions please use html-webpack-plugin 4.x
Entry javascript resources are now being loaded deferred in the <head> tag to improve the page load performance by default - You can set the scriptLoading option to 'blocking' to keep the previous behaviour
Setting publicPath to '' (an empty string) will no longer calculate a relative path from the html file to the assets anymore - You can set the publicPath option to 'auto' to keep the previous behaviour
Plugins for html-webpack-plugin which add additional assetTags should provide a meta attribute
Drop support for appcache-webpack-plugin
