This was already the case in the experimental 0.5.0 mode. * 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. + * References Resolver: Turn missing storage locations into an error. This was already the case in the experimental 0.5.0 mode. * Syntax Checker: Named return values in function types are an error. * Syntax Checker: Disallow unary ``+``. This was already the case in the experimental 0.5.0 mode. * View Pure Checker: Strictly enfore state mutability. This was already the case in the experimental 0.5.0 mode. |
