* Added an update_column method on ActiveRecord. This new method updates a given attribute on an object, skipping validations and callbacks. It is recommended to use #update_attribute unless you are sure you do not want to execute any callback, including the modification of the updated_at column. It should not be called on new records.

* Singular associations (has_one, belongs_to) no longer have a proxy and simply returns the associated record or nil. This means that you should not use undocumented methods such as bob.mother.create - use bob.create_mother instead.
* Support the :dependent option on has_many :through associations. For historical and practical reasons, :delete_all is the default deletion strategy employed by association.delete(*records), despite the fact that the default strategy is :nullify for regular has_many. Also, this only works at all if the source reflection is a belongs_to. For other situations, you should directly modify the through association.

* The behavior of association.destroy for has_and_belongs_to_many and has_many :through is changed. From now on, 'destroy' or 'delete' on an association will be taken to mean 'get rid of the link', not (necessarily) 'get rid of the associated records'.
