Is there a detailed OS X Change log out there?

I'm looking for a site that gives a detailed and comprehensive list of the changes between each version of OS X (ie 10.1 to 10.2 to 10.3 etc.)



This would encompass both features and more importantly navigation changes (ie the evolution of the system preferences, so if I were to help someone over the phone repair their internet, how would the button positions and layouts differ from OS 10.3 to 10.4).



Thanks in advanced.Is there a detailed OS X Change log out there?
The function of preference files is similar in OS 9 and OS X, so I would say they have carried over for more than a decade. This is one of a dozen details about Mac OS 9 and earlier that made the transition to a UNIX-based system fairly smooth.



I don't know of anything from Apple that shows a chronology of Mac OS, but the link below is useful. Scroll down to the section ';Versions';.



I've used Mac OS almost daily from OS 7.5 to now and I can say that the differences you would encounter between 10.2 and 10.4 are so few as to be insignificant. Network setup is identical. The big difference is in the function that lies in the background. OS 10.4 can use more advances applications, most notably those related to video and audio. For 10.5, I would say there are a few advances in the ability to use advanced applications, but the big difference is in some important system functions, such as partitioning without erasing data, Time Machine, Cover Flow, and multi-touch keypad.



Even so, there are some minor differences in all major releases of OS X. I did telephone support for Apple for many years and I can assure you, 90 percent of the calls can be handled from one computer with the latest OS installed. The other ten percent require occasionally taking a look at older systems, so you would need at least three computers. For tech support today, you need to have the option to look quickly at 10.2, 10.4, and 10.5. Add a 10.3 system as a luxury.
