The only way for a human language to stay the same is for people to stop speaking it, i.e. Latin - France has trouble keeping French the same, and English is the polar opposite with no ruling body and a history of katamari damacy-ing words from every other language.
Words can mean multiple things, and if there's enough of a gap a new word or usage will rise to fill its place.
Delete works, of course, and I think the opposite to "new feature just dropped" in tech circles is "killed" or "killed off", as in killedbygoogle.com
