  (note: suicide is deprecated).

• Include keccak256() as an alias to sha3().
• Support shifting constant numbers.

Bugfixes:

• Commandline interface: Disallow unknown options in solc.
• Name resolver: Allow inheritance of enum definitions.
• Type checker: Proper type checking for bound functions.
• Type checker: fixed crash related to invalid fixed point constants
• Type checker: fixed crash related to invalid literal numbers.
• Type checker: super.x does not look up x in the current contract.
• Code generator: expect zero stack increase after super as an expression.
• Code generator: fix an internal compiler error for L.Foo for enum Foo defined in library L.
• Code generator: allow inheritance of enum definitions.
• Inline assembly: support the address opcode.
• Inline assembly: fix parsing of assignment after a label.
• Inline assembly: external variables of unsupported type (such as this, super, etc.)
  are properly detected as unusable.
• Inline assembly: support variables within modifiers.
