The change to make all INPUT fields 100% width should have been an option, not forced upon existing users and certainly not something that is a "point" change because it breaks existing layouts. Can you please considering reverting that and make it some sort of wp-config option instead?
I understand the desire for the default but shouldn't that be set for new installs instead of existing installs? Now it means that the update requires us to go back and change all existing code just to prevent the 100% width from taking effect.
And since this is a large breaking change shouldn't it be in a major update instead of a minor / bug-fix update?
