-*   Fixed ActiveRecord::Relation#becomes! and changed_attributes issues for type column
+*   PostgreSQL, no longer disables user triggers if system triggers can't be
+    disabled. Disabling user triggers does not fulfill what the method promises.
+    Rails currently requires superuser privileges for this method.
+
+    If you absolutely rely on this behavior, consider patching
+    `disable_referential_integrity`.

+
+*   Restore aborted transaction state when `disable_referential_integrity` fails
+    due to missing permissions.

+    *Toby Ovod-Everett*, *Yves Senn*
+
+*   PostgreSQL, print warning message if `disable_referential_integrity` fails
+    due to missing permissions.
+
+    *Andrey Nering*, *Yves Senn*
+
+*   Allow `:limit` option for MySQL bigint primary key support.
+
+    Example:
+
+        create_table :foos, id: :primary_key, limit: 8 do |t|
+        end
+
+        # or
+
+        create_table :foos, id: false do |t|
+          t.primary_key :id, limit: 8
+        end
+
+    *Ryuta Kamizono*
+
+*   `belongs_to` will now trigger a validation error by default if the association is not present.
+    You can turn this off on a per-association basis with `optional: true`.
+    (Note this new default only applies to new Rails apps that will be generated with
+    `config.active_record.belongs_to_required_by_default = true` in initializer.)
