As promised, v3.0.5 is finally here ready for download. Per made a great five minute video tour earlier this week, which you can watch to see what's new.
And new it is indeed. We've made a good number of performance, stability and load-balancing fixes as well as making umbraco much more enjoyable for all you Firefox-savvy people.
Downloads and a full change log is on CodePlex, an installer and the source can be downloaded early next week.
Enjoy!
