Mike Dietrich erklärt die Unterschiede der Konzepte deprecated und desupported:
Deprecated is a signal that something may disappear in the future and does not get enhanced anymore. No activity required except of taking note for your future plans. Desupported means that we don't fix anything anymore for a desupported feature or product - and it may even disappear. But often desupported features are still there and can be used on your own risk only.
Diese Begriffe habe ich in der Vergangenheit mit Sicherheit auch eher unscharf verwendet.
