# WAI Quantum: deprecations Each item of a WAI Quantum public surface that is deprecated, the version that deprecated it, its replacement, and the version that removes it (or will). An item is listed here from the release that deprecates it, at least one minor release before the release that removes it; removal comes only in a major release (before 1.0, a 0.y release). What is public, and how a deprecated item says so where it is used, is in [VERSIONING.md](VERSIONING.md). | Package | Item | Deprecated in | Replacement | Removed in | |---|---|---|---|---| Nothing is deprecated today.
