        *   Renamed `"binary"` output mode to `"multi_hot"` for
            `CategoryEncoding`, `StringLookup`, `IntegerLookup`, and
            `TextVectorization`. Multi-hot encoding will no longer automatically
            uprank rank 1 inputs, so these layers can now multi-hot encode
            unbatched multi-dimensional samples.
        *   Added a new output mode `"one_hot"` for `CategoryEncoding`,
