It was *such* a major change that Value and its ilk were completely replaced, not moved aside. Value was a lazy value. The original transforms system was based on lazy evaluation of expressions, for the sake of efficiency. (The new transforms system achieves the same sort of efficiency but in a more general and extensible framework.) To port code, you really have to look not for replacements for things like Value, but for how the structure changed so that they are not needed. Essentially, you have to look at one level higher than the Value level--look at what you were trying to do with the code, not at how you implemented it via Value. Unless you were using Value et al for your own purposes, rather than in Bbox etc, looking at this higher level should take you straight to the translations in the table that Mike made to help guide the transition.
