 ### Features
 
+* (x/bank) [#14045](https://github.com/cosmos/cosmos-sdk/pull/14045) Add CLI command `spendable-balances`, which also accepts the flag `--denom`.
+* (x/slashing, x/staking) [#14363](https://github.com/cosmos/cosmos-sdk/pull/14363) Add the infraction a validator commited type as an argument to a `SlashWithInfractionReason` keeper method.
 * (client) [#13867](https://github.com/cosmos/cosmos-sdk/pull/13867/) Wire AutoCLI commands with SimApp.
 * (x/distribution) [#14322](https://github.com/cosmos/cosmos-sdk/pull/14322) Introduce a new gRPC message handler, `DepositValidatorRewardsPool`, that allows explicit funding of a validator's reward pool.
-* (x/slashing, x/staking) [#14363](https://github.com/cosmos/cosmos-sdk/pull/14363) Add the infraction a validator committed type as an argument to a `SlashWithInfractionReason` keeper method.
 * (x/evidence) [#13740](https://github.com/cosmos/cosmos-sdk/pull/13740) Add new proto field `hash` of type `string` to `QueryEvidenceRequest` which helps to decode the hash properly while using query API.
 * (core) [#13306](https://github.com/cosmos/cosmos-sdk/pull/13306) Add a `FormatCoins` function to in `core/coins` to format sdk Coins following the Value Renderers spec.
 * (math) [#13306](https://github.com/cosmos/cosmos-sdk/pull/13306) Add `FormatInt` and `FormatDec` functions in `math` to format integers and decimals following the Value Renderers spec.
