the best way to know is to found MFT Zeiss data-sheet, or buy both, try and tell us...
There are two reasons for recalculating an optic: a glass becomes unavailable (case of the 38mm biogon) or the optical quality does not meet users' expectations (case of the 80F2.8 hasselblad in its early days ...)
If the recalculation of the 110mm is contemporaneous with that of the biogon, we can think of the first possibility (taking into account the stocks to be exhausted), otherwise, it is advisable to push the investigation a little further to see if there is not an opportunity to find one of the two models better suited to the subjects photographed and the desired rendering ...
I have only one 110F2.0, in PQS/6008 mount, I believe it is last FE formula, it is good as you can expect for such wide open lense... (like noctilux F1.0, canon 50F0.95....not like noctilux F0.95)
You want it? : you need it!
You need it? : you must have!
