@ -8,6 +8,7 @@ Compiler Features:
Bugfixes:
* Code Generator: Avoid including references to the deployed label of referenced functions if they are called right away.
* ContractLevelChecker: Properly distinguish the case of missing base constructor arguments from having an unimplemented base function.
* SMTChecker: Fix internal error when using the custom NatSpec annotation to abstract free functions.
* TypeChecker: Also allow external library functions in ``using for``.
