 # Changelog
 
+
+## 5.5.0-rc.0 (2025-09-26)
+
 ### Bug fixes
 
 - `ERC165Checker`: Ensure the `supportsERC165` function returns false if the target reverts during the `supportsInterface(0xffffffff)` call. ([#5810](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5880))
 
 ### Breaking changes
 
-- `ERC6909` and the its extensions (`ERC6909ContentURI`, `ERC6909Metadata` and `ERC6909TokenSupply`) are no longer marked as draft since [EIP-6909](https://eips.ethereum.org/EIPS/eip-6909) is now final. Developers must update the import paths. Contracts behavior is not modified.
-- `SignerERC7702` is renamed as `SignerEIP7702`. Imports and inheritance must be updated to that new name and path. Behavior is unmodified.
-- `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`.
+- `ERC6909` and its extensions (`ERC6909ContentURI`, `ERC6909Metadata` and `ERC6909TokenSupply`) are no longer marked as draft since [EIP-6909](https://eips.ethereum.org/EIPS/eip-6909) is now final. Developers must update the import paths. Contracts behavior is not modified. ([#5929](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5929))
+- `SignerERC7702` is renamed as `SignerEIP7702`. Imports and inheritance must be updated to that new name and path. Behavior is unmodified. ([#5932](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5932))

Developers using their upgradeable variants from `@openzeppelin/contracts-upgradeable` must update their imports to use the equivalent version available in `@openzeppelin/contracts`. ([#5944](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5944), [#5942](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5942))
 - Update minimum pragma to 0.8.24 in `Votes`, `VotesExtended`, `ERC20Votes`, `Strings`, `ERC1155URIStorage`, `MessageHashUtils`, `ERC721URIStorage`, `ERC721Votes`, `ERC721Wrapper`, `ERC721Burnable`, `ERC721Consecutive`, `ERC721Enumerable`, `ERC721Pausable`, `ERC721Royalty`, `ERC721Wrapper`, `EIP712`, `ERC4626` and `ERC7739`. ([#5726](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5726))
 
 ### Deprecation
 
-- `Initializable` and `UUPSUpgradeable` are no longer transpiled. An alias is present in the `@openzeppelin/contracts-upgradeable` package that redirect to the corresponding file in `@openzeppelin/contracts`. These alias 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.
-- `ECDSA` signature malleability protection is partly deprecated. See documentation for more details.

+
+### Changes by category
+
+#### Tokens
+
+- `ERC4626`: compute `maxWithdraw` using `maxRedeem` and `previewRedeem` so that changes to the preview functions affect the max functions. ([#5130](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5130))
+
+#### Cross-chain
+

+
+#### Cryptography
+

+
+##### Other
+
+- `WebAuthn`: Add a library for verifying WebAuthn Authentication Assertions. ([#5809](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5809))

+- `ECDSA`: Add `recoverCalldata` and `tryRecoverCalldata`, variants of `recover` and `tryRecover` that are more efficient when signatures are in calldata. ([#5788](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5788))
+- `SignatureChecker`: Add `isValidSignatureNowCalldata(address,bytes32,bytes calldata)` for efficient processing of calldata signatures. ([#5788](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5788))
+
+#### Structures
+
+- `Checkpoints`: Add a new checkpoint variant `Checkpoint256` using `uint256` type for the value and key. ([#5748](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5748))

+- `Bytes`: Add `splice(bytes,uint256)` and `splice(bytes,uint256,uint256)` functions that move a specified range of bytes to the start of the buffer and truncate it in place, as an alternative to `slice`. ([#5733](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5733))
+- `Bytes`: Add a `clz` function to count the leading zero bits in a `bytes` buffer. ([#5725](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/5725))
