+- Update to new upstrem release 3.7.0
+  * Fixed a bug in Augmentation returning an integer zero for
+    zero element of a group ring, being calculated as the sum
+    over an empty list. Now it will properly return the zero
+    element of the underlying ring
+  * Fixed a bug in PcPresentationOfNormalizedUnit that may cause
+    NaturalBijectionToPcNormalizedUnitGroup returning wrong
+    results for p>2.
