+Plone 6.0 makes changes to two viewlet managers:
+
+-   Plone 6.0 removes the `plone.documentactions` (`IDocumentActions`) viewlet manager.
+    In Plone 5.2 it was already empty.
+-   Plone 6.0 adds the `plone.belowcontentdescription` (`IBelowContentDescription`) viewlet manager.
+    By default this has no viewlets.
+
 One final change is that Plone 6.0 moves the `plone.footer` viewlet from `plone.app.layout/viewlets` to `plone.app.portlets`.
 The viewlet remains in manager `plone.portalfooter`.
 It renders the portlets from the `plone.footerportlets` portlet manager.
