 ## [Unreleased]
 
+## [v0.37.78] - TBD
+
+### Bug Fixes
+
+* (rest) [\#5508](https://github.com/cosmos/cosmos-sdk/pull/5508) Fix `x/distribution` endpoints to properly return height in the response.
+* (x/genutil) [\#5499](https://github.com/cosmos/cosmos-sdk/pull/) Ensure `DefaultGenesis` returns valid and non-nil default genesis state.
+* (x/genutil) [\#5775](https://github.com/cosmos/cosmos-sdk/pull/5775) Fix `ExportGenesis` in `x/genutil` to export default genesis state (`[]`) instead of `null`.
+* (genesis) [\#5086](https://github.com/cosmos/cosmos-sdk/issues/5086) Ensure `gentxs` are always an empty array instead of `nil`.
+
+### Improvements
+
+* (rest) [\#5648](https://github.com/cosmos/cosmos-sdk/pull/5648) Enhance /txs usability:
+  * Add `tx.minheight` key to filter transaction with an inclusive minimum block height
+  * Add `tx.maxheight` key to filter transaction with an inclusive maximum block height
