+# Release Notes for OpenMDAO 3.4.1
+
+November 13, 2020
+
+OpenMDAO 3.4.1 contains mostly bug fixes, and adds a complex-compatible
+two-argument arctangent function.
+
+PR #1760 allows multiple sets of src_indices to be given to connections.
+Previously, if an input was promoted using some set of src_indices, one could not connect an output to it using another set of src_indices.
+This difference in behavior has been fixed.
