 # Changelog
 
+
+## 4.9.0-rc.0 (2023-05-09)
+
+- `ReentrancyGuard`: Add a `_reentrancyGuardEntered` function to expose the guard status. ([#3714](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3714))
+- `ERC721Wrapper`: add a new extension of the `ERC721` token which wraps an underlying token. Deposit and withdraw guarantee that the ownership of each token is backed by a corresponding underlying token with the same identifier. ([#3863](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3863))
+- `EnumerableMap`: add a `keys()` function that returns an array containing all the keys. ([#3920](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3920))
+- `Governor`: add a public `cancel(uint256)` function. ([#3983](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3983))
+- `Governor`: Enable timestamp operation for blockchains without a stable block time. This is achieved by connecting a Governor's internal clock to match a voting token's EIP-6372 interface. ([#3934](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3934))
+- `Strings`: add `equal` method. ([#3774](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3774))
+- `IERC5313`: Add an interface for EIP-5313 that is now final. ([#4013](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4013))
+- `IERC4906`: Add an interface for ERC-4906 that is now Final. ([#4012](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4012))
+- `StorageSlot`: Add support for `string` and `bytes`. ([#4008](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4008))
+- `Votes`, `ERC20Votes`, `ERC721Votes`: support timestamp checkpointing using EIP-6372. ([#3934](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3934))
+- `ERC4626`: Add mitigation to the inflation attack through virtual shares and assets. ([#3979](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3979))
+- `Strings`: add `toString` method for signed integers. ([#3773](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3773))
+- `ERC20Wrapper`: Make the `underlying` variable private and add a public accessor. ([#4029](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4029))
+- `EIP712`: add EIP-5267 support for better domain discovery. ([#3969](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3969))
+- `AccessControlDefaultAdminRules`: Add an extension of `AccessControl` with additional security rules for the `DEFAULT_ADMIN_ROLE`. ([#4009](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4009))
+- `SignatureChecker`: Add `isValidERC1271SignatureNow` for checking a signature directly against a smart contract using ERC-1271. ([#3932](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3932))
+- `SafeERC20`: Add a `forceApprove` function to improve compatibility with tokens behaving like USDT. ([#4067](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4067))
+- `ERC1967Upgrade`: removed contract-wide `oz-upgrades-unsafe-allow delegatecall` annotation, replaced by granular annotation in `UUPSUpgradeable`. ([#3971](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3971))
+- `ERC20Wrapper`: self wrapping and deposit by the wrapper itself are now explicitelly forbiden. ([#4100](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4100))
+- `ECDSA`: optimize bytes32 computation by using assembly instead of `abi.encodePacked`. ([#3853](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3853))
+- `ERC721URIStorage`: Emit ERC-4906 `MetadataUpdate` in `_setTokenURI`. ([#4012](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4012))
+- `ShortStrings`: Added a library for handling short strings in a gas efficient way, with fallback to storage for longer strings. ([#4023](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4023))
+- `SignatureChecker`: Allow return data length greater than 32 from EIP-1271 signers. ([#4038](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4038))
+- `UUPSUpgradeable`: added granular `oz-upgrades-unsafe-allow-reachable` annotation to improve upgrade safety checks on latest version of the Upgrades Plugins (starting with `@openzeppelin/upgrades-core@1.21.0`). ([#3971](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3971))
+- `Initializable`: optimize `_disableInitializers` by using `!=` instead of `<`. ([#3787](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3787))
+- `Ownable2Step`: make `acceptOwnership` public virtual to enable usecases that require overriding it. ([#3960](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3960))
+- `UUPSUpgradeable.sol`: Change visibility to the functions `upgradeTo ` and `upgradeToAndCall ` from `external` to `public`. ([#3959](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3959))
+- `TimelockController`: Add the `CallSalt` event to emit on operation schedule. ([#4001](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4001))
+- Reformatted codebase with latest version of Prettier Solidity. ([#3898](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3898))
+- `Math`: optimize `log256` rounding check. ([#3745](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3745))
+- `ERC20Votes`: optimize by using unchecked arithmetic. ([#3748](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3748))
+- `Multicall`: annotate `multicall` function as upgrade safe to not raise a flag for its delegatecall. ([#3961](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3961))
+- `ERC20Pausable`, `ERC721Pausable`, `ERC1155Pausable`: Add note regarding missing public pausing functionality ([#4007](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4007))
+- `ECDSA`: Add a function `toDataWithIntendedValidatorHash` that encodes data with version 0x00 following EIP-191. ([#4063](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4063))
+- `MerkleProof`: optimize by using unchecked arithmetic. ([#3745](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/3745))
+
 ### Breaking changes
 
 - `EIP712`: Addition of ERC5267 support requires support for user defined value types, which was released in Solidity version 0.8.8. This requires a pragma change from `^0.8.0` to `^0.8.8`.
