Breaking Change in 0.4.0

Paths like /src/somefile.png used to be served in development, but only by accident. They never worked in production builds. Since 0.4.0, we don’t serve static files by default in development anymore either. This removes a dangerous inconsistency that we never intentionally supported.

If you need a static file to be part for the build, import it from JavaScript and you will get its filename. This ensures it gets included into the production build as well, and its filename contains the content hash.

If you used static files with <link href>, read this new guide on how to make sure these files get included into the builds. For example, you can replace <link href="/src/favicons/favicon-32.png"> with <link href="./src/favicons/favicon-32.png">, and then Webpack will recognize it and include it into the build.

If you referenced some other files from index.html, please file an issue to discuss your use case. In the meantime, you can serve them from a separate static server until your use case is supported.
