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.
