EVERYBODY wants that! And I mean ABSOLUTELY EVERYBODY! Updates are now mandatory everywhere, in both Windows and Linux, and GPU manufactureres would LOVE to make the old cards obsolete, even if technically the new cards aren't much better.
So expect to see the old certificate invalidated quickly and automatically, in the name of security, of course!
