The number one reason people give us for not upgrading to the latest version of WordPress is fear that their plugins won’t be compatible. As part of our continuing efforts to make WordPress core, plugin, and theme upgrades as painless as possible, Michael Adams developed and launched a beta of a new “Compatibility” feature in the plugin directory, powered by your votes. When viewing a plugin in the directory, select a WordPress version and a plugin version from the drop-downs. If there has been feedback about this WordPress / plugin version combination, we’ll show you what percentage of responses marked that combination as compatible vs how many marked it as incompatible.
If you log in, you’ll be able to help us gather this information! Just select a WordPress version / plugin version combination and click the “Works” or the “Broken” button. Please note that this shouldn’t be used to report minor issues with a plugin. You should mark a plugin as “Broken” only if its core functionality is truly broken when run on the specified WordPress version.
