### Deprecated

* (x/upgrade) [\#9906](https://github.com/cosmos/cosmos-sdk/pull/9906) Deprecate `UpgradeConsensusState` gRPC query since this functionality is only used for IBC, which now has its own [IBC replacement](https://github.com/cosmos/ibc-go/blob/2c880a22e9f9cc75f62b527ca94aa75ce1106001/proto/ibc/core/client/v1/query.proto#L54)
* (types) [\#10948](https://github.com/cosmos/cosmos-sdk/issues/10948) Deprecate the types.DBBackend variable and types.NewLevelDB function. They are replaced by a new entry in `app.toml`: `app-db-backend` and `tendermint/tm-db`s `NewDB` function. If `app-db-backend` is defined, then it is used. Otherwise, if `types.DBBackend` is defined, it is used (until removed: [\#11241](https://github.com/cosmos/cosmos-sdk/issues/11241)). Otherwise, Tendermint config's `db-backend` is used.
