 ### Improvements
 
+* [\#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`.
 * [\#11089](https://github.com/cosmos/cosmos-sdk/pull/11089]) Now cosmos-sdk consumers can upgrade gRPC to its newest versions.
 * [\#10439](https://github.com/cosmos/cosmos-sdk/pull/10439) Check error for `RegisterQueryHandlerClient` in all modules `RegisterGRPCGatewayRoutes`.
