Adobe Flash Player 10.3 Release Candidate

Adobe have a release candidate for their Flash player. I have installed the flashplugin-nonfree package in Debian from the contrib repository, so trying out the release candidate simply involved download and unpacking the Flash Player 10.3 Release Candidate 1 tar.gz from Adobe, and dropping libflashplayer.so into /usr/lib/flashplugin-nonfree.
