These checks can be disabled using ``unchecked { ... }``. * Code Generator: Cause a panic if a byte array in storage is accessed whose length is encoded incorrectly. + * Code Generator: Use ``revert`` with error signature ``Panic(uint256)`` and error codes instead of invalid opcode on failing assertions. + * Command Line Interface: JSON fields `abi`, `devdoc`, `userdoc` and `storage-layout` are now sub-objects rather than strings. * Command Line Interface: Remove the ``--old-reporter`` option. * Command Line Interface: Remove the legacy ``--ast-json`` option. Only the ``--ast-compact-json`` option is supported now. * General: Remove global functions ``log0``, ``log1``, ``log2``, ``log3`` and ``log4``. + * Parser: Exponentiation is right associative. ``a**b**c`` is parsed as ``a**(b**c)``. + * Scanner: Remove support for the ``\b``, ``\f``, and ``\v`` escape sequences. * Standard JSON: Remove the ``legacyAST`` option. * Type Checker: Function call options can only be given once. - * Type System: Unary negation can only be used on signed integers, not on unsigned integers. - * Type System: Disallow explicit conversions from negative literals and literals larger than ``type(uint160).max`` to ``address`` type. - * Type System: Disallow enums with more than 256 members. - * Parser: Exponentiation is right associative. ``a**b**c`` is parsed as ``a**(b**c)``. - * Code Generator: Use ``revert`` with error signature ``Panic(uint256)`` and error codes instead of invalid opcode on failing assertions. - * Type System: Explicit conversions from literals to integer type is as strict as implicit conversions. - * Type System: Explicit conversions from literals to enums are only allowed if the value fits in the enum. - * Type System: Explicit conversions between two types are disallowed if it changes more than one of sign, width or kind at the same time. * Type System: Declarations with the name ``this``, ``super`` and ``_`` are disallowed, with the exception of public functions and events. - * Type System: Disallow ``type(super)``. * Type System: Disallow ``msg.data`` in ``receive()`` function. - * Command Line Interface: JSON fields `abi`, `devdoc`, `userdoc` and `storage-layout` are now sub-objects rather than strings. - * Scanner: Remove support for the ``\b``, ``\f``, and ``\v`` escape sequences. + * Type System: Disallow ``type(super)``. + * Type System: Disallow enums with more than 256 members. + * Type System: Disallow explicit conversions from negative literals and literals larger than ``type(uint160).max`` to ``address`` type. + * Type System: Explicit conversions between two types are disallowed if it changes more than one of sign, width or kind at the same time. + * Type System: Explicit conversions from literals to enums are only allowed if the value fits in the enum. + * Type System: Explicit conversions from literals to integer type is as strict as implicit conversions. + * Type System: Unary negation can only be used on signed integers, not on unsigned integers. Language Features: * Super constructors can now be called using the member notation e.g. ``M.C(123)``. Bugfixes: - * Type Checker: Perform proper integer arithmetic when using constants in array length expressions. + * Type Checker: Perform proper truncating integer arithmetic when using constants in array length expressions. AST Changes: - * New AST Node ``IdentifierPath`` replacing in many places the ``UserDefinedTypeName`` - - -AST Changes: - * New node type: unchecked block - used for ``unchecked { ... }``. + * New AST Node ``IdentifierPath`` replacing in many places the ``UserDefinedTypeName``. + * New AST Node ``UncheckedBlock`` used for ``unchecked { ... }``. ### 0.7.6 (unreleased)
