 * [#13794](https://github.com/cosmos/cosmos-sdk/pull/13794) `types/module.Manager` now supports the
 `cosmossdk.io/core/appmodule.AppModule` API via the new `NewManagerFromMap` constructor.
 * [#14019](https://github.com/cosmos/cosmos-sdk/issues/14019) Remove the interface casting to allow other implementations of a `CommitMultiStore`.
+* [#14175](https://github.com/cosmos/cosmos-sdk/pull/14175) Add `server.DefaultBaseappOptions(appopts)` function to reduce boiler plate in root.go.
