Release Notes

OpenZeppelin/openzeppelin-contracts (@​openzeppelin/contracts)

v4.9.6

Compare Source

• Base64: Fix issue where dirty memory located just after the input buffer is affecting the result. (#​4929)

v4.9.5

Compare Source

• Multicall: Make aware of non-canonical context (i.e. msg.sender is not _msgSender()), allowing compatibility with ERC2771Context. Patch duplicated Address.functionDelegateCall in v4.9.4 (removed).

v4.9.4

Compare Source

• ERC2771Context and Context: Introduce a _contextPrefixLength() getter, used to trim extra information appended to msg.data.

v4.9.3

Compare Source

Note
This release contains a fix for GHSA-g4vp-m682-qqmp.

• ERC2771Context: Return the forwarder address whenever the msg.data of a call originating from a trusted forwarder is not long enough to contain the request signer address (i.e. msg.data.length is less than 20 bytes), as specified by ERC-2771. (#​4481)
• ERC2771Context: Prevent revert in _msgData() when a call originating from a trusted forwarder is not long enough to contain the request signer address (i.e. msg.data.length is less than 20 bytes). Return the full calldata in that case. (#​4484)

v4.9.2

Compare Source

• MerkleProof: Fix a bug in processMultiProof and processMultiProofCalldata that allows proving arbitrary leaves if the tree contains a node with value 0 at depth 1.

Compare Source

• Governor: Add a mechanism to restrict the address of the proposer using a suffix in the description.
