The biggest change we did that affected plugins was to eliminate native
widgets for IFRAMEs and overflow:auto elements, so that the parent widget
for all plugins is associated with the root of the toplevel content

There were no fundamental changes in rendering model, but there were some
general rendering changes that exposed bugs in the Linux Flash plugin in
windowless mode (see ).

"He was pierced for our transgressions, he was crushed for our iniquities;
the punishment that brought us peace was upon him, and by his wounds we are
healed. We all, like sheep, have gone astray, each of us has turned to his
own way; and the LORD has laid on him the iniquity of us all." [Isaiah
