 ### Improvements
 
+* (signing) [#14087](https://github.com/cosmos/cosmos-sdk/pull/14087) Add SignModeHandlerWithContext interface with a new `GetSignBytesWithContext` to get the sign bytes using `context.Context` as an argument to access state.
 * (server) [#14062](https://github.com/cosmos/cosmos-sdk/pull/14062) Remove rosetta from server start.
 * [13882] (https://github.com/cosmos/cosmos-sdk/pull/13882) Add tx `encode` and `decode` endpoints to amino tx service.
   > Note: These endpoints encodes and decodes only amino txs.

 * [#13794](https://github.com/cosmos/cosmos-sdk/pull/13794) Most methods on `types/module.AppModule` have been moved to 
 extension interfaces. `module.Manager.Modules` is now of type `map[string]interface{}` to support in parallel the new 
 `cosmossdk.io/core/appmodule.AppModule` API.
-* (signing) [#13701](https://github.com/cosmos/cosmos-sdk/pull/) Add `context.Context` as an argument to SignModeHandler's `GetSignBytes` method and `x/auth/signing.VerifySignature`. You can pass `nil` for now, it will only be used once SIGN_MODE_TEXTUAL is live.
+* (signing) [#13701](https://github.com/cosmos/cosmos-sdk/pull/) Add `context.Context` as an argument `x/auth/signing.VerifySignature`.
 * (x/group) [#13876](https://github.com/cosmos/cosmos-sdk/pull/13876) Add `GetMinExecutionPeriod` method on DecisionPolicy interface.
 * (x/auth)[#13780](https://github.com/cosmos/cosmos-sdk/pull/13780) Querying with `id` (type of int64) in `AccountAddressByID` grpc query now throws error, use account-id(type of uint64) instead.
 * (snapshots) [14048](https://github.com/cosmos/cosmos-sdk/pull/14048) Move the Snapshot package to the store package. This is done in an effort group all storage related logic under one package.
