+# Release 2.0.3
+
+2.0.3 is a maintenance release with no public API or ABI changes. Compared
+with 2.0.2, the project now has:
+
+* AddressSanitizer and UndefinedBehaviorSanitizer coverage in CI, so the
+  regular test suite is exercised under both sanitizers.
+* A repeatable `--cmake-arg` option for `scripts/mutation_test.py`, allowing
+  mutation runs to cover alternate CMake configurations such as ThreadSanitizer.
