This plugins appends the file modification time to style and script URLs, so that changes are effected immediately, even if the theme or plugin version is not changed.
It will not slow down your site because resources are only reloaded when they change.

A plugin that you must install. I can’t build a site without installing this plugin. I hope it gets updated regularly and supports newer versions of WordPress. I love you Albert Peschar.
This plugin is awesome. Solved my problem of css version in a flash. It should be by default in wordpress installation.
Seems to work well as intended!
This logic of adding a hash based on last edited date is pure genius and keeps our clients from seeing broken sites.
Amazing that it only has 100+ installs. Life was so much harder when I had to tell clients to clear their browser cache all the time, and users had a bad experience until their browser cache was refreshed. This plugin completely removes those hassles. Thanks a lot.
