1.
deprecated, not recommended, discouraged
Something that is officially or unofficially discouraged from use, though not outright prohibited. Very common in IT and software development contexts to describe outdated features, functions, or practices that should be avoided in favor of newer alternatives.

このライブラリは非推奨になったので、代替のライブラリに移行してください。
This library has been deprecated, so please migrate to an alternative library.
Formed from 非 (non-, not) + 推奨 (recommendation). Primarily used in IT, software development, and technical documentation as a direct equivalent of English "deprecated." Outside of tech, it can be used more generally for anything that is not recommended.
In software contexts, 非推奨 typically means a feature still works but will be removed in a future version and should be replaced with a newer alternative.
COMMON COLLOCATIONS:
- 非推奨になる: to become deprecated
- 非推奨のAPI: deprecated API
- 非推奨の機能: deprecated feature
- 非推奨警告: deprecation warning
SIMILAR WORDS:
- 推奨: recommended — the positive counterpart
- 廃止: abolished, discontinued — stronger than 非推奨; the feature has been completely removed
- 旧式: outdated, old-fashioned — describes something old but without the explicit discouragement
