Changes between Version 1 and Version 2 of Ticket #31282

-              v1
+              v2
+It seems that I can no longer pass a list of pks to RelatedManager.set(..).
+Alternatively, passing a list of objects works as expected.
 {{{
+>>> i = ProductImage.objects.get(pk=100)
+>>> p.images.set([100])
+>>> p = Product.objects.all()[0]
+>>> p
+<Product: <Product pk=587 barcode=041390007019>>
+>>> p.images.set([1])
