N360 product update

I've just received a second N360 product update via LU. The first one was this morning, the one fixing problems with Anti-Spam. This one required me to apply a patch/hotfix and restart Norton.

 

However, this second  product update was much smaller in size (193kb, roughly). I received this via an automatic LU rather than a manual one. Yet, I have had no need to apply a hotfix/patch for this one (even when manually doing a LU straight after). Has anyone else received this second product update.

Norton 360 V. 22.5.2.15
