After reading UL2.0 documentation which was provided in the answer to this question, I was trying to find any kind of data about Ultralight 1.0, in order to summarize changes or evolution of the protocol, so I would be able to determine what needs have been driving this protocol's evolution.
However, I've found nothing (related topics links at the end or beggining of UL2.0 wiki post, nor search results inside the wiki).
Maybe is it because UL1.0 is previous to the API and then it's not inside the wiki? If then, I've been looking for it outside the wiki, but with same results. Anyone knows where can I find data about the evolution of UL protocol, or a reference to UL1.0 as I have for UL2.0?
Thanks in advance
