-`Initializable`: Add `_initializableStorageSlot` function that returns a pointer to the storage struct. The function allows customizing with a custom storage slot with an `override`.
-`GovernorSuperQuorum`: Add a governance extension to support a super quorum. Proposals that meet the super quorum (and have a majority of for votes) advance to the `Succeeded` state before the proposal deadline.
-`P256`: Adjust precompile detection in `verifyNative` to consider empty `returndata` on invalid verification. Previously, invalid signatures would've reverted with a `MissingPrecompile` error in chains with RIP-7212 support.
-`GovernorVotesSuperQuorumFraction`: Add a variant of the `GovernorSuperQuorum` extensions where the super quorum is expressed as a fraction of the total supply.
