Strips ?ver= from front-end CSS and JavaScript URLs when it equals the WordPress version, hiding it from the page source. Plugin and theme versions are left alone.
Shows when a download was last updated and an optional version number above its content, reassuring buyers that the product is maintained.
Greets visitors who arrive through an affiliate link with a small banner naming the person who referred them, which builds trust and lifts conversions.
Replaces the version number on your theme's and plugins' CSS and JavaScript URLs with the file's last-modified time, so browsers and CDNs cache files for a long time but always fetch a fresh copy right after you change one.
Stops browsers on large screens from downloading huge image versions by leaving very wide sizes out of the responsive srcset list.
Replaces the ?ver= value on plugin and theme CSS and JavaScript files with a short hash, so scanners cannot read your exact plugin versions from the page source, while caches still refresh whenever a version changes.
Serves any post or page as clean Markdown when .md is added to its address (or ?format=markdown), and publishes an /llms.txt index of your pages and recent posts for AI tools.
Makes WordPress generate WebP versions instead of JPEG and PNG for every image size it creates on upload, which usually cuts image weight by a quarter or more.
Adds a dashboard widget with the PHP, database and WordPress versions, memory limit, upload limit and active theme at a glance.
Stops the long technical "background update" debug emails WordPress sends after automatic updates on development, beta and nightly versions.
Adds a lightweight /wp-json/site/v1/ping endpoint for uptime monitors. It answers 200 only when WordPress can reach the database, and 503 otherwise, without exposing any versions.
Shows a completely different menu in a theme location for each WPML language, for sites whose language versions have different structures rather than translated copies.
Links matching pages across your country sites (such as example.com, example.co.uk and example.com.au) with hreflang tags, assuming each page uses the same path on every domain.
