How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

N/A

Est. acquisition value

N/A

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

    We recently switched to WP Compress and the cache would stay stale even after content updates. This plugin helped change that!!!

    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!

    Whether I’m working on the frontend or the backend, I don’t want to change the version of my external files, each time I make a change.If you’re developing, this is a must-have!
