In the past I've used <base> tags to "version" a deploy. The index.html was in the root directory and all other assets (including API endpoints, as it was a single-page app) were in a timestamped subdirectory, with a <base> tag pointing to that subdirectory. It seemed to work well, but there are issues with <base> tags you should read up on first.
