@ -23,6 +23,8 @@ Bugfixes:
* Commandline Interface: When linking only accept exact matches for library names passed to the ``--libraries`` option. Library names not prefixed with a file name used to match any library with that name.
* SMTChecker: Fix internal error in magic type access (``block``, ``msg``, ``tx``).
* TypeChecker: Fix internal error when using user defined value types in public library functions.
* TypeChecker: Fix internal error when using arrays and structs with user defined value types before declaration.
* TypeChecker: Improved error message for constant variables with (nested) mapping types.
* Yul Assembler: Fix internal error when function names are not unique.
* Yul IR Generator: Do not output empty switches/if-bodies for empty contracts.
