+- Update to release 3.9.5
+  * Fix a bug in `Inverse` for non-normalized units.
+  * Turn `IsGroupOfUnitsOfMagmaRing`, `IsUnitGroupOfGroupRing`
+    and `IsNormalizedUnitGroupOfGroupRing` properties into
+    categories.
+  * Turn `IsSymmetric`, `IsUnitary` into properties.
+  * Implement computation of MIP-related invariants of p-groups
+    and their modular group algebras.
