[dependabot]

Bumps @openzeppelin/contracts from 4.5.0 to 4.7.1.

Release notes

Sourced from @​openzeppelin/contracts's releases.

v4.7.1

⚠️ This is a patch for a medium severity issue affecting SignatureChecker and a high severity issue affecting ERC165Checker. For more information visit the security advisories (1, 2).

• SignatureChecker: Fix an issue that causes isValidSignatureNow to revert when the target contract returns ill-encoded data. (#3552)
• ERC165Checker: Fix an issue that causes supportsInterface to revert when the target contract returns ill-encoded data. (#3552)

v4.7.0

• TimelockController: Migrate _call to _execute and allow inheritance and overriding similar to Governor. (#3317)
• CrossChainEnabledPolygonChild: replace the require statement with the custom error NotCrossChainCall. (#3380)
• ERC20FlashMint: Add customizable flash fee receiver. (#3327)
• ERC4626: add an extension of ERC20 that implements the ERC4626 Tokenized Vault Standard. (#3171)
• SafeERC20: add safePermit as mitigation against phantom permit functions. (#3280)
• Math: add a mulDiv function that can round the result either up or down. (#3171)
• Math: Add a sqrt function to compute square roots of integers, rounding either up or down. (#3242)
• Strings: add a new overloaded function toHexString that converts an address with fixed length of 20 bytes to its not checksummed ASCII string hexadecimal representation. (#3403)
• EnumerableMap: add new UintToUintMap map type. (#3338)
• EnumerableMap: add new Bytes32ToUintMap map type. (#3416)
• SafeCast: add support for many more types, using procedural code generation. (#3245)
• MerkleProof: add multiProofVerify to prove multiple values are part of a Merkle tree. (#3276)
• MerkleProof: add calldata versions of the functions to avoid copying input arrays to memory and save gas. (#3200)
• ERC721, ERC1155: simplified revert reasons. (#3254, (#3438))
• ERC721: removed redundant require statement. (#3434)
• PaymentSplitter: add releasable getters. (#3350)
• Initializable: refactored implementation of modifiers for easier understanding. (#3450)
• Proxies: remove runtime check of ERC1967 storage slots. (#3455)

Breaking changes

• Initializable: functions decorated with the modifier reinitializer(1) may no longer invoke each other.

v4.7.0-rc.0

This prerelease is now available for open review! Let us know your feedback and if you find any security issues.

We have a bug bounty with rewards of up to USD $25,000 and a special POAP for submitting a valid issue.

See the announcement for more details.

v4.6.0

• crosschain: Add a new set of contracts for cross-chain applications. CrossChainEnabled is a base contract with instantiations for several chains and bridges, and AccessControlCrossChain is an extension of access control that allows cross-chain operation. (#3183)
• AccessControl: add a virtual _checkRole(bytes32) function that can be overridden to alter the onlyRole modifier behavior. (#3137)
• EnumerableMap: add new AddressToUintMap map type. (#3150)
• EnumerableMap: add new Bytes32ToBytes32Map map type. (#3192)
• ERC20FlashMint: support infinite allowance when paying back a flash loan. (#3226)
• ERC20Wrapper: the decimals() function now tries to fetch the value from the underlying token instance. If that calls revert, then the default value is used. (#3259)
• draft-ERC20Permit: replace immutable with constant for _PERMIT_TYPEHASH since the keccak256 of string literals is treated specially and the hash is evaluated at compile time. (#3196)
• ERC1155: Add a _afterTokenTransfer hook for improved extensibility. (#3166)
• ERC1155URIStorage: add a new extension that implements a _setURI behavior similar to ERC721's _setTokenURI. (#3210)
• DoubleEndedQueue: a new data structure that supports efficient push and pop to both front and back, useful for FIFO and LIFO queues. (#3153)
• Governor: improved security of onlyGovernance modifier when using an external executor contract (e.g. a timelock) that can operate without necessarily going through the governance protocol. (#3147)
• Governor: Add a way to parameterize votes. This can be used to implement voting systems such as fractionalized voting, ERC721 based voting, or any number of other systems. The params argument added to _countVote method, and included in the newly added _getVotes method, can be used by counting and voting modules respectively for such purposes. (#3043)
