Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
Actively maintainedHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

I was impressed with the level of support provided with the recent issue where the plugin stopped displaying due to Mozilla’s PDFjs, and they started using mjs files. Thank you for an excellent plugin.

The plugin doesn’t work when it is updated to version 2.2. Are there any CORS issues?

After updating to v 2.2, pdf files are not displayed with a shortcode.I don’t want to underestimate the rating, because the plugin worked great for many years before.
