Microsoft Security Essentials new update?

Last Sept. 28, 2016, MSE came out with a new Definition Update, version, v 4.10.205 (KB3193414, 119 MB). I didn't d/l & install it because I thought I'd wait until I knew more about the advisability of installing it. But I see MSE is still updating the current version in WU: KB2310138 (Def. 1.239.etc ). Does anyone have any further info on the new MSE Update, because I can't find any info on it? What I'm basically asking is the new update reliable & easy to install?

Thanks for your reply.

I already use MSE & have updated it w/o any problems. Last def. update is also 1.239.1096.0. I'm merely curious why there doesn't seem to be any details/info about the supposed Sept. 28, 2016 Definition Update of KB3193414 since it came out--unless I've missed it. I'll keep searching...

Thanks, Layback Bear. You have clarified the issue for me, & my MSE is up to date. BTW, my browser is IE11--sorry for the confusion. Thank you again.
