Typical. The *day* after I stay up all night migrating from drupal to wordpress 2.6, they release wordpress 2.7 (Coltrane). How dare they give me shiny new goodness!
It's very shiny indeed. It took me all of 5 minutes to upgrade (with only one false attempt; fortunately, "bzr revert -r 1" saved me).
Is every day of being a wordpress user like this?
