CSS versioning / caching best practice

I recently ran into an issue where I updated some styling in /wp-content/uploads/espresso/templatesevent_espresso_style.css but the users of my site didn’t see the changes until at least a day later. I assume that’s due to typical browser caching of css and js files. That said when I “view source” of the affected pages, I can see that “?ver=3.4.1” is appended to the file path within the tag for the css file I changed.

My question is what’s the best practice for making sure that after making a change to css/js files I can force the browser to reload the changed resource? Is there a way to force an increment of the appended “ver” value? Also is this an Event Espresso or a WordPress feature?

Thanks in advance!

It’s a WordPress feature that can be overridden by using a plugin like this one:
