I have been busy testing the WordPress 3.1 beta and it is working very well indeed, no problems yet running on Apache2 webserver on my OpenSuse 11.3 machine. I used a local webserver instead of my website to run it as it made testing easier, and I used it to develop the new look of my website again, so I have the good looking index.php once more.
I cannot wait for the new version to go stable!
