An explicit conversion is now required before invoking an ``address`` member from a contract. * 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: Disallow functions without implementation to use modifiers. 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: Strictly require visibility specifier for functions. This was already the case in the experimental 0.5.0 mode. * Syntax Checker: Disallow unary ``+``. This was already the case in the experimental 0.5.0 mode. diff --git a/libsolidity/analysis/SyntaxChecker.cpp b/libsolidity/analysis/SyntaxChecker.cpp index 5d16a33f..77492499 100644 --- a/libsolidity/analysis/SyntaxChecker.cpp +++ b/libsolidity/analysis/SyntaxChecker.cpp @@ -213,8 +213,6 @@ bool SyntaxChecker::visit(ContractDefinition const& _contract) bool SyntaxChecker::visit(FunctionDefinition const& _function) { - bool const v050 = m_sourceUnit->annotation().experimentalFeatures.count(ExperimentalFeature::V050); - if (_function.noVisibilitySpecified()) { string suggestedVisibility = _function.isFallback() || m_isInterface ?
