I have complicated plug-ins which responsible for cache , it is paid plug-in
every update he required to re-place index.php

So if you update my blog automatically my server load will increase x10 times and could go even down. And 1 more thing that to press 1 button to update is not complicated.

I prefer to skip this update and if same politics will continue integrate, to do something without me , it could be hard to find what cause the issue. I will stay on 3.6 without future updates until in 4.0 it will be fixed or migrate to Joomla or Drupal . lets see what we will be in future
