MB oil specs

What's the difference between MB229.3 and MB 229.5? Does it represent a physical difference in the oil, or just the date at which the parameters were established?

My understanding about the specifications is that they are just approval.
I bet there is lot of oil that will be good, but since the manufacturer did not apply for approval, the approval was not process.
Oil recommendations are very tricky subject and generated tons of forum disputes.
MB does not disclosure detail but they do recommend the same oil for gasoline and diesel engine, what was big no-no on oil classes I had years ago.
So the rumors about "donations" that trigger the approval might have something to it.
