### 0.4.10 (unreleased)
Features:
* Commandline interface: Do not overwrite files unless forced.
* Add ``assert(condition)``, which throws if condition is false.
* Introduce ``.transfer(value)`` for sending Ether.
* Code generator: Support ``revert()`` to abort with rolling back, but not consuming all gas.
