@ -27,6 +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: Disallow specifying base constructor arguments multiple times in the same inheritance hierarchy. This was already the case in the experimental 0.5.0 mode.
* 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.
