Version 2.5.4 of the Akismet plugin for WordPress has been released. This is a maintenance release with minor fixes and improvements:
* Less Javascript and CSS is loaded in wp-admin
* Added link previews and a link removal button to comment moderation pages
* The Akismet configuration and stats pages are now under the Jetpack menu when Jetpack is installed.
* Old Akismet comment metadata is removed to save space
Read the changelog for full details.
Like all 2.5+ releases, this plugin requires WordPress 3.0 or higher. To upgrade, visit the Plugins tab of your wp-admin dashboard and follow the instructions.
Akismet 
Updated to the latest and the Akismet window still doesn’t fully open, it leaves a narrow one open at the top of the page with a scrollbar being the only way to view the stats.
There is an issue with Firefox and the stats page. We have a fix that will be included in the next version of the plugin. You can update the admin.php from http://plugins.trac.wordpress.org/export/560614/akismet/trunk/admin.php to get the fix now.
