@openzeppelin/contracts - npm Package Versions

4.4.2 (2022-01-11)

Bugfixes

• GovernorCompatibilityBravo: Fix error in the encoding of calldata for proposals submitted through the compatibility interface with explicit signatures. (#3100)

4.4.1 (2021-12-14)

• Initializable: change the existing initializer modifier and add a new onlyInitializing modifier to prevent reentrancy risk. (#3006)

Breaking change

It is no longer possible to call an initializer-protected function from within another initializer function outside the context of a constructor. Projects using OpenZeppelin upgradeable proxies should continue to work as is, since in the common case the initializer is invoked in the constructor directly. If this is not the case for you, the suggested change is to use the new onlyInitializing modifier in the following way:

 contract A {
-    function initialize() public   initializer { ... }
+    function initialize() internal onlyInitializing { ... }
 }
 contract B is A {
     function initialize() public initializer {
         A.initialize();
     }
 }

4.4.0 (2021-11-25)

• Ownable: add an internal _transferOwnership(address). (#2568)
• AccessControl: add internal _grantRole(bytes32,address) and _revokeRole(bytes32,address). (#2568)
• AccessControl: mark _setupRole(bytes32,address) as deprecated in favor of _grantRole(bytes32,address). (#2568)
• AccessControlEnumerable: hook into _grantRole(bytes32,address) and _revokeRole(bytes32,address). (#2946)
• EIP712: cache address(this) to immutable storage to avoid potential issues if a vanilla contract is used in a delegatecall context. (#2852)
• Add internal _setApprovalForAll to ERC721 and ERC1155. (#2834)
• Governor: shift vote start and end by one block to better match Compound's GovernorBravo and prevent voting at the Governor level if the voting snapshot is not ready. (#2892)
• GovernorCompatibilityBravo: consider quorum an inclusive rather than exclusive minimum to match Compound's GovernorBravo. (#2974)
• GovernorSettings: a new governor module that manages voting settings updatable through governance actions. (#2904)
• PaymentSplitter: now supports ERC20 assets in addition to Ether. (#2858)
• ECDSA: add a variant of toEthSignedMessageHash for arbitrary length message hashing. (#2865)
• MerkleProof: add a processProof function that returns the rebuilt root hash given a leaf and a proof. (#2841)
• VestingWallet: new contract that handles the vesting of Ether and ERC20 tokens following a customizable vesting schedule. (#2748)
• Governor: enable receiving Ether when a Timelock contract is not used. (#2849)
• GovernorTimelockCompound: fix ability to use Ether stored in the Timelock contract. (#2849)

4.3.3 (2021-11-08)

• ERC1155Supply: Handle totalSupply changes by hooking into _beforeTokenTransfer to ensure consistency of balances and supply during IERC1155Receiver.onERC1155Received calls.

4.3.2 (2021-09-14)

• UUPSUpgradeable: Add modifiers to prevent upgradeTo and upgradeToAndCall being executed on any contract that is not the active ERC1967 proxy. This prevents these functions being called on implementation contracts or minimal ERC1167 clones, in particular.

4.3.1 (2021-08-26)

• TimelockController: Add additional isOperationReady check.
