Webpack 3 support

Is there any planned support for webpack 3? I'm getting error
`        compiler.hooks.compilation.tap(pluginName, compilation => {
TypeError: Cannot read property 'compilation' of undefined
    at RtlCssPlugin.apply (\node_modules\rtl-css-transform-webpack-plugin\dist\plugin.js:46:24)
`
which I guess is because this plugin uses webpack 4.
