As far as I can tell, the Maxim folks still recommend... http://www.maximintegrated.com/app-notes/index.mvp/id/126 ...for things like the OneWire Library.
The differences between that document and the library are small...

The rules in table 2 here... Reading and Writing 1-Wire® Devices Through Serial Interfaces | Analog Devices ...are supposed to be used for networks with "new" and "old" devices. But I think Maxim is trying to achieve greater reliability over longer distances. I don't think that's within the scope of a general purpose Arduino library.
