### 0.6.12 (2020-07-22)
Language Features:
* NatSpec: Implement tag ``@inheritdoc`` to copy documentation from a specific base contract.
* Wasm backend: Add ``i32.ctz``, ``i64.ctz``, ``i32.popcnt``, and ``i64.popcnt``.
Compiler Features:
* Code Generator: Avoid double cleanup when copying to memory.
* Code Generator: Evaluate ``keccak256`` of string literals at compile-time.
* Optimizer: Add rule to remove shifts inside the byte opcode.
* Peephole Optimizer: Add rule to remove swap after dup.
* Peephole Optimizer: Remove unnecessary masking of tags.
* Yul EVM Code Transform: Free stack slots directly after visiting the right-hand-side of variable declarations instead of at the end of the statement only.
Bugfixes:
* SMTChecker: Fix error in events with indices of type static array.
* SMTChecker: Fix internal error in sequential storage array pushes (``push().push()``).
* SMTChecker: Fix internal error when using bitwise operators on fixed bytes type.
* SMTChecker: Fix internal error when using compound bitwise operator assignments on array indices inside branches.
* Type Checker: Fix internal compiler error related to oversized types.
* Type Checker: Fix overload resolution in combination with ``{value: ...}``.
Build System:
* Update internal dependency of jsoncpp to 1.9.3.
