 ### Breaking Changes
 - [\#355](https://github.com/cosmos/iavl/pull/355) `Get` in `iavlServer` no longer returns an error if the requested key does not exist. `GetResponse` now contains a `NotFound` boolean to indicate that a key does not exist, and the returned index will be that of the next occupied key.
 
 ### Improvements

+- [\#355](https://github.com/cosmos/iavl/pull/355) Add support for `GetByIndex` to `iavlServer` and RPC interface.

+### Bug Fixes
++ [\#385](https://github.com/cosmos/iavl/pull/385) Fix `GetVersioned` - now it works with `LazyLoadVersion`.
