 # Changelog
 
 
+## 4.9.4 (2023-12-07)
+
+- `ERC2771Context` and `Context`: Introduce a `_contextPrefixLength()` getter, used to trim extra information appended to `msg.data`.
+- `Multicall`: Make aware of non-canonical context (i.e. `msg.sender` is not `_msgSender()`), allowing compatibility with `ERC2771Context`.
+
 ## 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))
