first pass through CHANGELOGS to extract 4_1_release_notes. [ci skip]

Extract **notable changes**, **deprecations** and **removals** from
each CHANGELOG.

I tried to reference the commits and pull requests for new features
and deprecations.

In the process I also made some minor changes to the CHANGELOGS.

The 4_1_release_notes guide is declared WIP.

     This will help to catch subtle bugs like:
 
-      def recent?(days = 3)
-        self.created_at >= days.ago
-      end
+        def recent?(days = 3)
+          self.created_at >= days.ago
+        end
 
     The above code would check if the model is created within the last 3 **seconds**.
 
-    In the future, Numeric#{ago,until,since,from_now} should be removed completely,
+    In the future, `Numeric#{ago,until,since,from_now}` should be removed completely,
     or throw some sort of errors to indicate there are no implicit conversion from
     Numeric to AS::Duration.
