Since our latest update, we’ve also upgraded a few other Performancing WordPress themes for maximum compatibility with WordPress 2.7 and above.

Similar to the earlier upgrades, these new versions include provisions for threaded comments, post classes, image classes and gravatar support.

Again, while only a few core files were changed in these, we recommend backing up your existing theme folder and uploading the updated folder (copying modifications you have made), just to make sure it works.
