+- `SuperToken` now implements [EIP-2612](https://eips.ethereum.org/EIPS/eip-2612) (permit extension for EIP-20 signed approvals).
+- `SuperfluidPool` now has additional methods `increaseMemberUnits` and `decreaseMemberUnits` which allow the pool admin to change member units parameterized with delta amounts.
+
+### Breaking
+- `SuperfluidPool` does no longer mint and burn EIP-721 tokens (NFTs) on member unit updates. The gas overhead of this operation caused friction for integrations with other protocols (e.g. Uniswap V4).
