No, not a treatment for high blood pressure but the new beta version 2 of Blogger. It does look to have some enhancements - the one I would be most interested in is the facility to add labels to posts. At the moment, fiddling with the template is only allowed through the new user-friendly interface - you can't yet do it in raw html and css. So I'm keeping the old template until this is allowed. Unfortunately, this means labels can't yet be used.
