 ### Features
 
+* (types) [#23919](https://github.com/cosmos/cosmos-sdk/pull/23919) Add MustValAddressFromBech32 function.
 * (all) [23708](https://github.com/cosmos/cosmos-sdk/pull/23708) Add unordered transaction support.
   * Adds a `--timeout-timestamp` flag that allows users to specify a block time at which the unordered transactions should expire from the mempool.
