The name and packaging changes differentiate different emulsions. The change took place in, I think, 2007. Films made from 2007 onward are referenced in the 2007 Kodak 4016 PDF.
The older versions of T-Max 100 developed in T-Max Developer used the following temperature/time combinations for small-tank processing:
20°C, 8 minutes (current version 7.5minutes)
21°C, 7.5 minutes (current version 7 minutes)
22°C, 7 minutes (current version 6.5 minutes)
24°C, 6 ½ minutes (current version 6 ¼ minutes)
The emulsions were changed, not the developer. Don’t put much faith in the Massive Development Chart. Some values are correct. Some became obsolete as emulsions changed. Some have always been wrong. Trust the film-maker’s data. Better still, do your own testing using the maker’s data as a starting point.
Here’s the older data in the 2002 Kodak PDF F32
