Version 3.1.8 of the Akismet plugin for WordPress is now available.
This update improves compatibility with plugins that rewrite admin URLs. It also reduces the amount of space Akismet uses in the database and reduces the size of the Akismet API requests. A fix is also included for a bug that could have caused comment moderation emails to be sent for some comments that were caught as spam.
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.
