i was curious to know litespeed 4.1.1 is really ready to be used in production servers ? presently i am using 4.0.20 on my server and pretty much happy with it but 4.1.x seems to have much more features / optimization which is making me lean towards upgrade ,so i was keeping an eye on forum to see whether any major issues encountered but i see many petty issues arising and build is regularly updated , so i want to ask community whether i should upgrade now or still wait ?
