I understand that Vernish + Apache makes the websites load much faster even faster than using Litespeed or nginx.

I need to know first when 6.5.1 version will be out because it has the option to switch to Vernish

And secondly, what tutorial to follow to do it on my server, I see a member called
Jakarta added a tutorial here
http://forum.lxcenter.org/index.php?t=msg&goto=104513& . I wonder if its still fine to use it to implement Varnish on my server and if the settings will remain there on Kloxo-MR updates.

I see people on this forum (
Spacedust indeed) keep complaining about issues that shows up after updated to last version, or in general after Kloxo-RM updates. So, is it dangerous to use yum update ?, better to block kloxo-RM updates ?, make server backup before update,etc ? I don't want to move all my sites to Kloxo-RM panel and get in trouble after some update although I'am sure Mustafa its always there to help as to fix the problem.
