@ -12,6 +12,7 @@ Bugfixes:
* Optimizer: fix related to stale knowledge about SHA3 operations
* Disallow unknown options in ``solc``.
* Proper type checking for bound functions.
* Type Checker: ``super.x`` does not look up ``x`` in the current contract.
* Code Generator: expect zero stack increase after `super` as an expression.
* Allow inheritance of ``enum`` definitions.
* Inline assembly: support the ``address`` opcode.
