 ## [Unreleased]
 
+### Improvements
+
+* (x/genutil) [#17296](https://github.com/cosmos/cosmos-sdk/pull/17296) Add `MigrateHandler` to allow reuse migrate genesis related function.
+    * In v0.46, v0.47 this function is additive to the `genesis migrate` command. However in v0.50+, adding custom migrations to the `genesis migrate` command is directly possible.
+
 ## [v0.46.14](https://github.com/cosmos/cosmos-sdk/releases/tag/v0.46.14) - 2023-07-17
