The emacs 20.4-5 packages add global key bindings for \C-h and [delete]. That's REALLY RUDE for those of us who have been using Emacs for years, have our Emacs configured exactly the way we want it, and don't want anything to change. There's already a mechanism in Emacs for making C-h do the right thing on systems where the backspace key generates C-h. See, for example, the "Keyboard Translations" node in the Emacs info page. Alternatively, people can remap their backspace key to delete using xmodmap; that is what I do, and that remapping broke because of the global bindings you added. And shame on you for making this patently user-visible change without documenting it in the changelog.
I am not sure what change are you talking about - we did not patch any of the keybindings for emacs in the package we shipped
