v5.6.1

Compare Source

• InteroperableAddress: Fix overflow in the parsing functions that caused silent misparse of large interoperable addresses. (#​6372)

v5.6.0

Compare Source

Breaking changes

• Strings: The escapeJSON function now escapes all control characters in the range U+0000 to U+001F per RFC-4627. Previously only backspace, tab, newline, form feed, carriage return, double quote, and backslash were escaped. Input strings containing any other control character (e.g. null 0x00) or raw bytes in U+0001–U+001F will now produce different, longer output (e.g. \u0000 for null). (#​6344)
• ERC1155: Performing batch transfers with exactly one id/value in the batch no-longer calls IERC1155Receiver.onERC1155Received. IERC1155Receiver.onERC1155BatchReceived is called instead (with arrays of length one). (#​6170)
• ERC1967Proxy and TransparentUpgradeableProxy: Mandate initialization during construction. Deployment now reverts with ERC1967ProxyUninitialized if an initialize call is not provided. Developers that rely on the previous behavior and want to disable this check can do so by overriding the internal _unsafeAllowUninitialized function to return true. (#​5906)
• ERC721 and ERC1155: Prevent setting an operator for address(0). In the case of ERC721 this type of operator allowance could lead to obfuscated mint permission. (#​6171)
• RLP: The encode(bytes32) function now encodes bytes32 as a fixed size item and not as a scalar in encode(uint256). Users must replace calls to encode(bytes32) with encode(uint256(bytes32)) to preserve the same behavior. (#​6167)
• ERC4337Utils: The parseValidationData now returns a ValidationRange as the last return tuple value indicating whether the validationData is compared against a timestamp or block number. Developers must update their code to handle this new return value (e.g. (aggregator, validAfter, validUntil) -> (aggregator, validAfter, validUntil, range)). (#​6215)
• SignerWebAuthn: The _rawSignatureValidation function now returns false when the signature is not a valid WebAuthn authentication assertion. P256 fallback is removed. Developers can add it back by overriding the function. (#​6337)
• Memory: The setFreeMemoryPointer function is renamed to unsafeSetFreeMemoryPointer. Developers should use unsafeSetFreeMemoryPointer instead of setFreeMemoryPointer after v5.6.0. (#​6348)
• Memory: Remove the asBytes32 and asPointer function to reduce the risk of mistakes when manipulating memory pointers. (#​6340)

Changes by category

Account

• Account: Update default version of the ERC-4337 entrypoint to v0.9. (#​6135)
• AccountERC7579: Do not revert and perform the uninstall if the onUninstall hook of a module reverts. (#​6142)
• ERC4337Utils: Added the paymasterSignature function to extract the signature in paymasterAndData after Entrypoint v0.9. Similarly, a variant of paymasterData that receives a flag to exclude the signature from the returned data. (#​6215)
• ERC4337Utils: Added variants of packValidationData(address,uint48,uint48) and packValidationData(bool,uint48,uint48) that receive a ValidationRange argument, could be timestamp or block number. Similarly, the parseValidationData now returns a ValidationRange too. (#​6215)

Tokens

• ERC1155: Introduce the _checkAuthorized internal virtual function to encapsulate isApprovedForAll and msg.sender == from checks. (#​6133)
• ERC1155: Call IERC1155Receiver.onERC1155BatchReceived when performing a batch transfers with exactly one id/value in the batch. (#​6170)
• ERC4626: Allow overriding underlying assets transfer mechanisms through new internal virtual functions (_transferIn and _transferOut). (#​5970)
• ERC721URIStorage: Add _suffixURI, an internal getter for retrieving the custom tokenURI without the base prefix. (#​6175)
• Add ERC-165 detection for the IERC6909ContentURI, IERC6909TokenSupply and IERC6909Metadata interfaces in the ERC6909ContentURI, ERC6909TokenSupply and ERC6909Metadata contracts respectively. (#​6246) and (#​6247)

Cross-chain

• BridgeFungible, BridgeERC20 and BridgeERC7802: Added bridge contracts to handle crosschain movements of ERC-20 (and ERC-7802) tokens. (#​5914) (#​6328)
• CrosschainLinked: Added a new helper contract to facilitate communication between a contract on one chain and counterparts on remote chains through ERC-7786 gateways. (#​5914)
• ERC20Crosschain: Added an ERC-20 extension to embed an ERC-7786 based crosschain bridge directly in the token contract. (#​5914)
• InteroperableAddress: Reject inputs with both chain reference and addresses empty. (#​6340)

Cryptography

• MessageHashUtils: Add helper functions to build EIP-712 domain typehash and separator with fields selectively enabled/disabled. (#​5908)
• SignatureChecker: Add isValidERC1271SignatureNowCalldata, a variant of isValidERC1271SignatureNow that takes the signature from calldata. (#​6123)
• TrieProof: Add library for verifying Ethereum Merkle-Patricia trie inclusion proofs. (#​5826)
• WebAuthn: Verification now returns false instead of reverting when client data contains an out-of-bounds challengeIndex. (#​6329)

Structures

• Accumulator: Check that slices being added (shift or push) are in the reserved space. (#​6302)
• DoubleEndedQueue: Add tryPushBack, tryPopBack, tryPushFront, tryPopFront, tryFront, tryBack, and tryAt function variants that do not revert. (#​6020)
• EnumerableMap: Add support for Bytes4ToAddressMap types. (#​6091)
• EnumerableSet: Add support for Bytes4Set type. (#​6091)

Utils

• Arrays: Add replace functions enabling in-place array modification of address[], bytes32[] and uint256[] arrays, with new content from another array. (#​5995)
• Arrays: Add slice and splice functions for value types (uint256[], bytes32[], address[]). (#​5965)
• Bytes: Add replace functions that replaces a portion of a bytes buffer with content from another buffer. (#​5995)
• Bytes: Add the toNibbles function that expands the nibbles (4 bits chunk) of a bytes buffer. Used for manipulating Patricia Merkle Trees keys and paths. (#​5826)
• Memory: Add a isReserved(Slice) function that checks if the memory occupied by the slice is reserved (i.e. before the free memory pointer). (#​6302)
• RLP: Encode bytes32 as a fixed size item and not as a scalar in encode(bytes32). Scalar RLP encoding remains available by casting to a uint256 and using the encode(uint256) function. (#​6167)
• RLP: Fix RLP encoding validity check when decoding long lists or strings (#​6051)
• RLP: Perform a memory copy when decoding bytes objects containing a single byte instead of returning a reference to the input. (#​6303)

v5.5.0

Compare Source

Bug fixes

• AccountERC7579: Prevent revert in isModuleInstalled for fallback modules when additionalContext has fewer than 4 bytes. The function now returns false instead of reverting, ensuring ERC-7579 compliance. (#​5961)
• ERC165Checker: Ensure the supportsERC165 function returns false if the target reverts during the supportsInterface(0xffffffff) call. (#​5880)
• AccountERC7579: Prevent revert in isModuleInstalled for fallback modules when additionalContext has fewer than 4 bytes. The function now returns false instead of reverting, ensuring ERC-7579 compliance. (#​5961)

Breaking changes

• Account: Add signature argument to the internal _validateUserOp function for custom signature handling logic. Developers overriding it must now provide the signature from the user operation (i.e. userOp.signature) to keep compatibility. (#​5976)
• AccountERC7579: Installing and uninstalling fallback modules now require the corresponding initData and deInitData arguments to be at least 4 bytes long (matching the selector to which the fallback module is registered). It now reverts with ERC7579CannotDecodeFallbackData instead of treating the missing bytes as 0x00. (#​5974)
• ERC6909 and its extensions (ERC6909ContentURI, ERC6909Metadata and ERC6909TokenSupply) are no longer marked as draft since EIP-6909 is now final. Developers must update the import paths. Contracts behavior is not modified. (#​5929)
• SignerERC7702 is renamed as SignerEIP7702. Imports and inheritance must be updated to that new name and path. Behavior is unmodified. (#​5932)
• ERC721Holder, ERC1155Holder, ReentrancyGuard and ReentrancyGuardTransient are flagged as stateless and are no longer transpiled. Developers using their upgradeable variants from @openzeppelin/contracts-upgradeable must update their imports to use the equivalent version available in @openzeppelin/contracts. (#​5944, #​5942)
• Update minimum pragma to 0.8.24 in AccessControlEnumerable, Arrays, CircularBuffer, EIP712, EnumerableMap, EnumerableSet, ERC1155, ERC1155Burnable, ERC1155Pausable, ERC1155Supply, ERC1155URIStorage, ERC20Votes, ERC4626,ERC721Burnable, ERC721Consecutive, ERC721Enumerable, ERC721Pausable, ERC721Royalty, ERC721URIStorage, ERC721Votes, ERC721Wrapper, ERC7739, Heap, MerkleTree, MessageHashUtils, Strings, Votes and VotesExtended. (#​5723, #​5726, #​5965)

Deprecation

• Initializable and UUPSUpgradeable are no longer transpiled. Aliases are present in the @openzeppelin/contracts-upgradeable package that redirect to the corresponding files in @openzeppelin/contracts. These aliases will be removed in the next major release. Developers are advised to update their imports to get these files directly from the @openzeppelin/contracts package. #​5941
• ECDSA signature malleability protection is partly deprecated. See documentation for more details. #​5814
