Use ``abi.encodePacked`` for unpadded encoding. * Code Generator: Signed right shift uses proper arithmetic shift, i.e. rounding towards negative infinity. Warning: this may silently change the semantics of existing code! @@ -22,6 +27,7 @@ Breaking Changes: * Parser: Disallow trailing dots that are not followed by a number. * Type Checker: Disallow arithmetic operations for boolean variables. * Type Checker: Disallow conversions between ``bytesX`` and ``uintY`` of different size. + * Type Checker: Only accept a single ``bytes`` type for ``.call()`` (and family), ``keccak256()``, ``sha256()`` and ``ripemd160()``. * 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. |
