Version 3.0.4 of the Akismet plugin for WordPress is now available.
This update adds better compatibility with Apache 2.4, allows https author URLs to be removed from comments, removes the “Check for Spam” button from the “Trash” and “Approved” queues, and allows for automatic API key configuration when Jetpack is installed and connected to a WordPress.com account.
To upgrade, visit the Updates page of your WordPress dashboard and follow the instructions. If you need to download the plugin zip file directly, links to all versions are available in the WordPress plugins directory.
