+*   Remove deprecated arguments in `assert_nothing_raised`.
+
+    *Rafel Mendonça França*
+
+*   `Date.to_s` doesn't produce too many spaces. For example, `to_s(:short)`
+    will now produce `01 Feb` instead of ` 1 Feb`.
+
+    Fixes #25251.
+
+    *Sean Griffin*
+
+*   Introduce Module#delegate_missing_to.
+
+    When building a decorator, a common pattern emerges:
+
+        class Partition
+          def initialize(first_event)
+            @events = [ first_event ]
+          end
+
+          def people
+            if @events.first.detail.people.any?
+              @events.collect { |e| Array(e.detail.people) }.flatten.uniq
+            else
+              @events.collect(&:creator).uniq
+            end
+          end
+
+          private
+            def respond_to_missing?(name, include_private = false)
+              @events.respond_to?(name, include_private)
+            end
+
+            def method_missing(method, *args, &block)
+              @events.send(method, *args, &block)
+            end
+        end
+
+    With `Module#delegate_missing_to`, the above is condensed to:
+
+        class Partition
+          delegate_missing_to :@events
+
+          def initialize(first_event)
+            @events = [ first_event ]
+          end
+
+          def people
+            if @events.first.detail.people.any?
+              @events.collect { |e| Array(e.detail.people) }.flatten.uniq
+            else
+              @events.collect(&:creator).uniq
+            end
+          end
+        end
+
+    *Genadi Samokovarov*, *DHH*
+
+*   Rescuable: If a handler doesn't match the exception, check for handlers
+    matching the exception's cause.
+
+    *Jeremy Daer*
