+### 0.6.3 (2020-02-18)
+
+Language Features:
+ * Allow contract types and enums as keys for mappings.
+ * Allow function selectors to be used as compile-time constants.
+ * Report source locations for structured documentation errors.
+
+
+
+Compiler Features:
+ * AST: Add a new node for doxygen-style, structured documentation that can be received by contract, function, event and modifier definitions.
+ * Code Generator: Use ``calldatacopy`` instead of ``codecopy`` to zero out memory past input.
+ * Debug: Provide reason strings for compiler-generated internal reverts when using the ``--revert-strings`` option or the ``settings.debug.revertStrings`` setting on ``debug`` mode.
+ * Yul Optimizer: Prune functions that call each other but are otherwise unreferenced.
+
+
+Bugfixes:
+ * Assembly: Added missing `source` field to legacy assembly json output to complete the source reference.
+ * Parser: Fix an internal error for ``abstract`` without ``contract``.
+ * Type Checker: Make invalid calls to uncallable types fatal errors instead of regular.
+
