Serious New Java Flaw Affects All Versions of Windows
I think that's what this update 20 addresses, if I'm not mistaken. Update 19 just came out a couple weeks ago, so the fast manner in which 20 came out is apparently to plug this flaw.
It normally uninstalls the old version but I found it sometimes leaves behind old Firefox plugins so I now make sure it is clean before installing the new version.
