 ### CLI Breaking Changes
 
+* (x/genutil) [#13535](https://github.com/cosmos/cosmos-sdk/pull/13535) Replace in `simd init`, the `--staking-bond-denom` flag with `--default-denom` which is used for all default denomination in the genesis, instead of only staking.
 * (tx) [#12659](https://github.com/cosmos/cosmos-sdk/pull/12659) Remove broadcast mode `block`.
