 ### API Breaking Changes
 
+* (x/crisis) [#16216](https://github.com/cosmos/cosmos-sdk/issues/16216) `NewKeeper` now takes a `KVStoreService` instead of a `StoreKey`, methods in the `Keeper` now take a `context.Context` instead of a `sdk.Context` and return an `error` instead of panicking.
 * (x/gov) [#15988](https://github.com/cosmos/cosmos-sdk/issues/15988) `NewKeeper` now takes a `KVStoreService` instead of a `StoreKey`, methods in the `Keeper` now take a `context.Context` instead of a `sdk.Context` and return an `error` (instead of panicking or returning a `found bool`). Iterators callback functions now return an error instead of a `bool`.
 * (x/auth) [#15985](https://github.com/cosmos/cosmos-sdk/pull/15985) The `AccountKeeper` does not expose the `QueryServer` and `MsgServer` APIs anymore.
 * (x/authz) [#15962](https://github.com/cosmos/cosmos-sdk/issues/15962) `NewKeeper` now takes a `KVStoreService` instead of a `StoreKey`, methods in the `Keeper` now take a `context.Context` instead of a `sdk.Context`. The `Authorization` interface's `Accept` method now takes a `context.Context` instead of a `sdk.Context`.
