Summary: `metro-bundler` v0.21 contains a rewritten bundling mechanism, with simplified logic and much faster rebuild times, called delta bundler. This release contains a couple of breaking changes: * Now, when using a custom transformer, the list of additional babel plugins to apply are passed to the `transform()` method. These are used in non-dev mode for optimization purposes (Check https://github.com/facebook/metro-bundler/commit/367a5f5db805a9445e6f07ba9551d4fba259d1c7#diff-40653f0c822ac59a5af13d5b4ab31d84 to see how to handle them from the transformer). * Now, when using a custom transformer outputting `rawMappings`, the transformer does not need to call the `compactMappings` method before returning (check https://github.com/facebook/metro-bundler/commit/d74685fd1d292cde18ee332e835921a99b0c0d66#diff-40653f0c822ac59a5af13d5b4ab31d84 for more info). * We've removed support for two config parameters: `postProcessModules` and `postProcessBundleSourcemap`.
