Breaking Changes in 0.5.0

Global ESLint Plugin Versions

If you used a global ESLint installation for the editor integration, you’ll need to install these versions of global ESLint packages.

Moving index.html into public Folder

You’ll also need to create a new folder called public in the root of your project. Then, move index.html and files it references (such as a favicon) into that folder.

You can no longer reference any files from ./src in index.html. Instead, public/index.html can now only reference files other inside of the public folder using a special variable called %PUBLIC_URL%.

For example, instead of:

<link rel="shortcut icon" href="./src/favicon.ico">

You would need to move both index.html and src/favicon.ico into the public folder, and change <link> to look like this:

<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico">

This ensures it become a part of the build output, and resolves correctly both with client-side routing and non-root homepage in package.json. Read more about using the public folder and why these changes were made.
