Many people I am sure are confused as to why their existing enhancements are taking so long to ugprade. Essentially, Sage went to what is called “object oriented programming” with level 4.X. This is as large a change as when DOS went to Windows. Senior Programmers have instantly become Junior Programmers. Each and every enhancement has to be rewritten in a language that most programmers have to learn from scratch. The programs have to be rewritten as the module gets adapted to OOP. For example, when Sales Order changed to 4.10, then all enhancements that affect Sales Order have to be rewritten at that time.
