   This change may increase the file size of your bundles, and may change some behavior in your app if your code touches upon one of the edge cases where Loose mode differs from native JavaScript. There are notes in the linked PR about how to turn Loose mode back on if you need to, but consider migrating to Compiler Assumptions when you can. If you have already customized your babel config, this change probably won't affect you.

   Rather than calculating SHA digest of all the files in the paths watched by the compiler, we are now comparing the modified time of the `manifest.json` file versues the latest modified timestamp of files and directories in watched paths. Unlike calculating digest, which only looked at the files, the new calculation also considers directory timestamps, including the parent ones (i.e. `config.source_path` folder timestamp will be checked together will timestamps of all files and directories inside of it).
