 Versioning in SilverStripe is handled through the [Versioned](api:SilverStripe\Versioned\Versioned) class. As a [DataExtension](api:SilverStripe\ORM\DataExtension) it is possible to be applied to any [DataObject](api:SilverStripe\ORM\DataObject) subclass. The extension class will automatically update read and write operations done via the ORM via the `augmentSQL` database hook.
 
+<div class="notice" markdown="1">
+There are two complementary modules that improve content editor experience around "owned" nested objects (e.g. elemental blocks).
+Those are in experimental status right now, but we would appreciate any feedback and contributions.
+
+You can check them out on github:
+  - https://github.com/silverstripe/silverstripe-versioned-snapshots
+  - https://github.com/silverstripe/silverstripe-versioned-snapshot-admin
+
+The first one adds extra metadata to versions about object parents at the moment of version creation.
+The second module extends CMS History UI adding control over nested objects.

+##### Rewriting asset references{#tagtoshortcode}
 
 Your `img` and `a` tag references to your assets may now be pointing to a location in your assets folder that has been moved. There is a task available which will look through all your tables containing `HTMLText` and `HTMLVarchar` fields looking for broken references and then rewrite them to the new location of the file.
