In #8396 (first released in @apollo/client@3.5.0-beta.0), we adopted the Node.js recommendation to specify "type": "module" in package.json, so all .js modules within the @apollo/client package will be interpreted (correctly) as ECMAScript modules. Since we also provide various CommonJS bundles for consumption by Node.js and older bundlers, those CommonJS bundles now have a .cjs file extension, rather than .cjs.js, so Node.js won't misinterpret them as ECMAScript modules.

Unfortunately, as I was first made aware by @SimenB in apollographql/zen-observable-ts#156 (comment), switching to a .cjs file extension for CommonJS bundles can cause problems for React Native's Metro bundler. This PR updates our CHANGELOG.md to provide guidance on a workaround until facebook/metro#535 is resolved. I wish we could solve this problem unilaterally, but it seems like the React Native / Metro maintainers will have to take action here.
