XF 1.3 Xenforo Hidden Testing OutDated Feature?

i never seen this b4 not untill i upgraded to 1.3.1

so i am unsure if this is some add one doing this or something that xenforo came with...


See the Red Outlined 11 <-- what is this?

the other columns, Update checker, Rebuild add one caches, Install & Upgrade thats from an add one i know...

i just want to be clear if the Outdated Add-ones is apart of the Xenforo Core Installation as there was no mention of this in update email i got from xenforo...

+ any other hidden features 1.3.1?
