 ### Bug Fixes
 
 * [\#9401](https://github.com/cosmos/cosmos-sdk/pull/9401) Fixes incorrect export of IBC identifier sequences. Previously, the next identifier sequence for clients/connections/channels was not set during genesis export. This resulted in the next identifiers being generated on the new chain to reuse old identifiers (the sequences began again from 0).
+* [\#9408](https://github.com/cosmos/cosmos-sdk/pull/9408) Update simapp to use correct default broadcast mode.
 
 * [\#9513](https://github.com/cosmos/cosmos-sdk/pull/9513) Fixes testnet CLI command. Testnet now updates the supply in genesis. Previously, when using add-genesis-account and testnet together, inconsistent genesis files would be produced, as only add-genesis-account was updating the supply.
