An excuse isn't needed. How will it change your life not knowing 1-2 insignificant changes? A large amount of patchlogs don't even list the most minor of the changes, so aren't "complete" either.
Whats your problem here to begin with? Complaining for the sake of complaining?
Change logs are absolute common place in software development work, especially when the company has worked to address issues which have been documented, it doesn't take more than a few moments to drop a note of the changes onto the official forum of the game, I don't think the request for them to be posted is at all unreasonable, he's not complaining for the joy of it, he's complaining because its an irregular practice not to do it.
The fan boys on here reminds me of the phrase "unsinkable rubber ducks"
