-- ⚡ Added "Load Style" methods to `TMVCActiveRecord` as suggested by https://github.com/danieleteti/delphimvcframework/issues/675
+- ⚡ Added "Load Style" methods to `TMVCActiveRecord` (more info https://github.com/danieleteti/delphimvcframework/issues/675)
+
+  - `TMVCActiveRecord` support "Factory Style" and "Load Style" methods when loads data from database.
+
+    Using "Factory Style" methods (available from the first version) the result list is returned by the loader method (as shown in this piece of code from the `activerecord_showcase` sample).
+
+    ```delphi
+      Log('>> RQL Query (2) - ' + cRQL2);
+      lCustList := TMVCActiveRecord.SelectRQL<TCustomer>(cRQL2, 20);
+      try
+        Log(lCustList.Count.ToString + ' record/s found');
+        for lCustomer in lCustList do
+        begin
+          Log(Format('%5s - %s (%s)', [lCustomer.Code.ValueOrDefault,
+            lCustomer.CompanyName.ValueOrDefault, lCustomer.City]));
+        end;
+      finally
+        lCustList.Free;
+      end;
+    ```
+
+    For some scenarios would be useful to have also "Load Style" methods where the list is filled by the loader method (not instantiated internally).
+
+    ```delphi
+      Log('>> RQL Query (2) - ' + cRQL2);
+      lCustList := TObjectList<TCustomer>.Create;
+      try
+        lRecCount := TMVCActiveRecord.SelectRQL<TCustomer>(cRQL2, 20, lCustList); //new in 3.4.0-neon
+        Log(lRecCount.ToString + ' record/s found');
+        for lCustomer in lCustList do
+        begin
+          Log(Format('%5s - %s (%s)', [lCustomer.Code.ValueOrDefault,
+            lCustomer.CompanyName.ValueOrDefault, lCustomer.City]));
+        end;
+      finally
+        lCustList.Free;
+      end;
+    ```
