 * `files` lists patterns that match files in the distribution directory. These can be single files or glob-like patterns that match a number of files.
 
-* `versionedFiles` is like `files` but should be used for build artifacts that already include a hash in the filename, which is used for cache busting. The Angular service worker can optimize some aspects of its operation if it can assume file contents are immutable.
+* `versionedFiles` has been deprecated. As of v6 `versionedFiles` and `files` options have the same behavior. Use `files` instead.
 
 * `urls` includes both URLs and URL patterns that will be matched at runtime. These resources are not fetched directly and do not have content hashes, but they will be cached according to their HTTP headers. This is most useful for CDNs such as the Google Fonts service.<br>
