منسوخ

Also known as obsoleteness

Obsolescence is the process of becoming antiquated, out of date, old-fashioned, no longer in general use, no longer useful, or superseded by innovation, or the condition of being in such a state. When used in a biological sense, it means imperfect or rudimentary when compared with the corresponding part of other organisms. The international standard IEC 62402:2019 Obsolescence Management defines obsolescence as the "transition from available to unavailable from the manufacturer in accordance with the original specification".
