# Description In the past we named the process of completely removing a command and providing a basic error message pointing to the new alternative "deprecation". But this doesn't match the expectation of most users that have seen deprecation _warnings_ that alert to either impending removal or discouraged use after a stability promise. # User-Facing Changes Command category changed from `deprecated` to `removed`
