@ -22,6 +22,7 @@ Breaking Changes:
* Modifiers: return does not skip part in modifier after ``_``
* Placeholder statement `_` in modifier now requires explicit `;`.
* ``ecrecover`` now returns zero if the input is malformed (it previously returned garbage)
* The ``constant`` keyword cannot be used for constructors or the fallback function.
* Removed ``--interface`` (Solidity interface) output option
* JSON AST: General cleanup, renamed many nodes to match their C++ names.
* Json Output: srcmap-runtime renamed to srcmapRuntime
