+*   `preload` preserves readonly flag for associations.

+    See #15853.

+
+*   Assume numeric types have changed if they were assigned to a value that
+    would fail numericality validation, regardless of the old value. Previously
+    this would only occur if the old value was 0.
+
+    Example:
+
+        model = Model.create!(number: 5)
+        model.number = '5wibble'
+        model.number_changed? # => true
+
+    Fixes #14731.

+
+*   `reload` no longer merges with the existing attributes.
+    The attribute hash is fully replaced. The record is put into the same state
+    as it would be with `Model.find(model.id)`.
+
+    *Sean Griffin*
+
+*   The object returned from `select_all` must respond to `column_types`.
+    If this is not the case a `NoMethodError` is raised.
+
+    *Sean Griffin*
+
 *   `has_many :through` associations will no longer save the through record
     twice when added in an `after_create` callback defined before the
     associations.
