# ActivityPub 9.0

A new major version of ActivityPub, the WordPress plugin that lets people on Mastodon and other fediverse apps follow your site.

Version 9.0 adds a setting that controls how quickly posts reach followers. Images get a blurred preview that other fediverse apps can show while the images load. The release also has ten security fixes.
