 ### Improvements
 
+* [\#11511](https://github.com/cosmos/cosmos-sdk/pull/11511) Add api server flags to start command.
 * [\#11484](https://github.com/cosmos/cosmos-sdk/pull/11484) Implement getter for keyring backend option.
 * [\#11449](https://github.com/cosmos/cosmos-sdk/pull/11449) Improved error messages when node isn't synced.
 * [\#11349](https://github.com/cosmos/cosmos-sdk/pull/11349) Add `RegisterAminoMsg` function that checks that a msg name is <40 chars (else this would break ledger nano signing) then registers the concrete msg type with amino, it should be used for registering `sdk.Msg`s with amino instead of `cdc.RegisterConcrete`.
