* (x/mint) [#25599](https://github.com/cosmos/cosmos-sdk/pull/25599) Add max supply param.
* (x/gov) [#25615](https://github.com/cosmos/cosmos-sdk/pull/25615) Decouple `x/gov` from `x/staking` by making `CalculateVoteResultsAndVotingPowerFn` a required parameter to `keeper.NewKeeper` instead of `StakingKeeper`.
`BondedTokens` has been renamed to `ValidatorPower` and `TotalBondedTokens` has been renamed to `TotalValidatorPower` to allow for multiple validator power representations.
