Those got updated in 1.1.0 Live, yes. Whether intended by HBS as a bugfix/balancing pass or not, though...
I am guessing it is an accident, as it isn't noted in the patch notes. Also, some of the <blank>, + and ++ values changed.
So, it appears that the Actuator values on the actuators that were updates all swapped their "InventorySize" and "Tonnage" values. There are also a number of occasions where the + / ++ values changed and wasn't sure if that was intentional.
Here is an example from the Gear_Actuator_Coventry_B40-Extended.json file:

With 1.1 do I have to reapply this patch?
Yes - these would need to be reapplied.
Though, I have now integrated the 'Mechs, Vehicles and Weapons fixes into the Variants mod at least.
