Perfect solution

Especially after the update to allow a custom version string, either through a GUI setting or programmatic hook, this plugin fixes a persistent problem when doing site updates. Too often we have browsers holding onto cached CSS/etc after doing an update. We want them cached, but wanted a way to invalidate those when changes are made. This now allows us to use the version as a “point in time” refresh point. Caching will happen until we tell it a new version is installed. It works perfect for us. Thanks so much to Mwale for sharing this freely!
