Hi John, good idea in principle, but the amount of incompatible code changes between versions is surprisingly large. On top of that, XDS philosophy has always been that there is a single "best" algorithm (which may be fine-tuned in subsequent releases). The main arguments for that are: - it is scientifically more satisfactory - it is a support nightmare to have more than one versions/ algorithms.
