[Q] update SuperSU in play store? topic

I updated some apps a couple days ago in the google play store and noticed that there is an update for SuperSU. So my question is should I update SuperSU that way? And do I even need the update?
My current version of SuperSU is v1.34 and I have android 4.1.2.

I rooted my xcover 2 about a month ago using these instructionshttp://forum.xda-developers.com/showthread.php?p=40232503#post40232503 .

Thanks in advance!
