### 0.8.4 (unreleased)
|
||||
|
||||
Important Bugfixes:
|
||||
* ABI Decoder V2: For two-dimensional arrays and specially crafted data in memory, the result of ``abi.decode`` can depend on data elsewhere in memory. Calldata decoding is not affected.
|
||||
|
||||
|
||||
Language Features:
|
||||
* Assembly / Yul: Allow hex string literals.
|
||||
* Possibility to use ``bytes.concat`` with variable number of ``bytes`` and ``bytesNN`` arguments which behaves as a restricted version of `abi.encodePacked` with a more descriptive name.

"description": "The ABI specification uses pointers to data areas for everything that is dynamically-sized. When decoding data from memory (instead of calldata), the ABI decoder did not properly validate some of these pointers. More specifically, it was possible to use large values for the pointers inside arrays such that computing the offset resulted in an undetected overflow. This could lead to these pointers targeting areas in memory outside of the actual area to be decoded. This way, it was possible for ``abi.decode`` to return different values for the same encoded byte array.",
