The page for the Release Candidate version of Flash 10.1 contains this text:

"Adobe® Flash® Player 10.1 is the first runtime release of the Open Screen Project that enables uncompromised Web browsing of expressive applications, content and video across devices."

Does putting the words "Adobe" and "uncompromised web browsing" in the same sentence constitute false advertising, a warranty or just wishful thinking on their part? :-)

So everyone is going to rush to queue up a Release Candidate of 10.1 to 'patch' this vulnerability? I think not...are we waiting for more 10.0.x.x updates, or will 10.1 be Release quality soon?

I decided to only run the flash un-installer that was provided on the RC page and see how painful or not it is to not have flash.

I also wonder if those that do install the RC will actually read the RC directions and do the un-install step first before installing the RC. And is the un-install just one of those preferred steps or a real requirement.

My attempt to do without flash didn't even last 2 hours. OpenDNS uses flash for some of it's 'stats' information. So RC7 (10.1) it is.

I imagine that a lot of web pages are probably broken without flash

Adobe updated the bulletin to provide release dates for Flash (10 June) and Acrobat products (29 June).

Firefox users: use Flashblock extension to only allow Flash in your browser on a case-by-case basis, i.e. block it until you want it.
