New Features

MONGOID-5930 Add Mongoid::Config.allow_reparenting_via_nested_attributes (PR)

Add Mongoid::Config.allow_reparenting_via_nested_attributes, defaulting to true. When false, this prevents dependent has_many records from being reparented via use of nested attributes. When true, records may be reparented via nested attributes.

This setting will default to false in Mongoid 9.1, and will be removed in Mongoid 10.

MONGOID-5751 avoid unnecessary autosaves of unchanged subtrees (PR)

The legacy behavior of associations with autosave: true resulted in all #save being invoked on all children of those associations, whether those children actually needed it or not. All corresponding after_save hooks were invoked as well, recursively, clear to the bottom of the autosave tree.

This PR adds an option to change this behavior, ensuring that subtrees are only autosaved if there are any changed documents in the subtree.

Mongoid.autosave_saves_unchanged_documents = true

The default is true, allowing the legacy behavior to prevail. If your program depends on this legacy behavior, you are encouraged to rewrite the affected code and set the value to false. The default value of this option will be false in Mongoid 9.1, and will go away in Mongoid 10. At that point the legacy autosave behavior will be removed.
