Feel free to offer your reasons for your answers. I'm aware of people (some very experienced) who are no longer able to run in ultrapeer mode effectively or suffer some related problems. Not to mention a sudden rash of crashes or other odd behaviour due to the new version. The beta seemed to be added to the official version rather rashly/hastily. How about sorting out the problems before releasing it as an "official" version. Almost as though there was a race against time to get "something" out.
