Deprecation

Deprecation is the discouragement of use of something human-made, such as a term, feature, design, or practice. Typically something is deprecated because it is claimed to be inferior compared to other options available.

Something may be deprecated when it cannot be controlled,^{[clarification needed]} such as a term. Even when it can be controlled, something may be deprecated even when it might be useful – for example, to ensure compatibility – and it may be removed or discontinued at some time after being deprecated.^[1]
