v4.8.0

Note Don't miss the section on Breaking changes at the end.

• Governor: make the relay function payable, and add support for EOA payments. (#3730)
• GovernorCompatibilityBravo: remove unused using statements. (#3506)
• ERC20: optimize _transfer, _mint and _burn by using unchecked arithmetic when possible. (#3513)
• ERC20Votes, ERC721Votes: optimize getPastVotes for looking up recent checkpoints. (#3673)
• ERC20FlashMint: add an internal _flashFee function for overriding. (#3551)
• ERC4626: use the same decimals() as the underlying asset by default (if available). (#3639)
• ERC4626: add internal _initialConvertToShares and _initialConvertToAssets functions to customize empty vaults behavior. (#3639)
• ERC721: optimize transfers by making approval clearing implicit instead of emitting an event. (#3481)
• ERC721: optimize burn by making approval clearing implicit instead of emitting an event. (#3538)
• ERC721: Fix balance accounting when a custom _beforeTokenTransfer hook results in a transfer of the token under consideration. (#3611)
• ERC721: use unchecked arithmetic for balance updates. (#3524)
• ERC721Consecutive: Implementation of EIP-2309 that allows batch minting of ERC721 tokens during construction. (#3311)
• ReentrancyGuard: Reduce code size impact of the modifier by using internal functions. (#3515)
• SafeCast: optimize downcasting of signed integers. (#3565)
• ECDSA: Remove redundant check on the v value. (#3591)
• VestingWallet: add releasable getters. (#3580)
• VestingWallet: remove unused library Math.sol. (#3605)
• VestingWallet: make constructor payable. (#3665)
• Create2: optimize address computation by using assembly instead of abi.encodePacked. (#3600)
• Clones: optimized the assembly to use only the scratch space during deployments, and optimized predictDeterministicAddress to use fewer operations. (#3640)
• Checkpoints: Use procedural generation to support multiple key/value lengths. (#3589)
• Checkpoints: Add new lookup mechanisms. (#3589)
• Arrays: Add unsafeAccess functions that allow reading and writing to an element in a storage array bypassing Solidity's "out-of-bounds" check. (#3589)
• Strings: optimize toString. (#3573)
• Ownable2Step: extension of Ownable that makes the ownership transfers a two step process. (#3620)
• Math and SignedMath: optimize function max by using > instead of >=. (#3679)
• Math: Add log2, log10 and log256. (#3670)
• Arbitrum: Update the vendored arbitrum contracts to match the nitro upgrade. (#3692)

Breaking changes

• ERC721: In order to add support for batch minting via ERC721Consecutive it was necessary to make a minor breaking change in the internal interface of ERC721. Namely, the hooks _beforeTokenTransfer and _afterTokenTransfer have one additional argument that may need to be added to overrides:

 function _beforeTokenTransfer(
     address from,
     address to,
     uint256 tokenId,
</tr></table>
