@ -19,6 +19,7 @@ Breaking Changes:
|
||||
* Type Checker: Disallow arithmetic operations for boolean variables.
|
||||
* Type Checker: Disallow conversions between ``bytesX`` and ``uintY`` of different size.
|
||||
* Remove obsolete ``std`` directory from the Solidity repository. This means accessing ``https://github.com/ethereum/soldity/blob/develop/std/*.sol`` (or ``https://github.com/ethereum/solidity/std/*.sol`` in Remix) will not be possible.
|
||||
* Syntax Checker: Named return values in function types are an error.
|
||||
|
||||
Language Features:
|
||||
* General: Allow appending ``calldata`` keyword to types, to explicitly specify data location for arguments of external functions.
