# Changelog


## 4.9.3 (2023-07-28)

- `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](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/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](https://github.com/OpenZeppelin/openzeppelin-contracts/pull/4484))

## 4.9.2 (2023-06-16)

- `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.
