I just updated to the last RC candidate. When I reopened Orion, the main page was displayed upside down!
There was nothing I could do make right-side up.
Well, obviously I expected this to be right side up! As it stands now, I have to use my laptop upside down to get to websites.
The other thing I expect is that you realize that this is just a lame April Fool's Joke!
