WordPress 2.8.1 is now available for download or upgrade according to the WordPress Development Blog. This release includes a bunch of bug fixes and security updates, including an important one that affects a few plugins (details here). The update highlights are listed on the dev blog post and all the changes since 2.8 are on the Trac. I don’t see the upgrade bar on this blog yet, but it should be soon. Since 2.8.1 is now released, I wish Dev4Press would redo their benchmarks.
