I'll just say this (after decades of software engineering...) the humor is appreciated, but NOT unique to updating products.
Take a look at what Google, Youtube and a host of others have been doing for years with their mobile (iPhone, Android) updates. It's funny stuff, and I see absolutely no reason that, within the bounds of professionalism, humor can't exist.
Update notices do not have to be clinically sterile, dry and mundane expressions of purely technical data.
What would bother me a LOT MORE is if they just said: Bug fixes and product improvements.
No animals were harmed making the update or delivering it, no one was shot or injured, no one was slurred, everyone's rights were preserved, and it's not a bad thing to remember that the people making this game are fellow human beings, too. They laugh like us, and have families like us and it's good to see they can take the game seriously, and make fun of themselves (or even us...) in the same breath.
Keep doing it as respectfully as you've done, Inno. As a fellow software engineer, I truly believe it does not reduce your professionalism in any way, shape or form.
But in this modern world, everyone will share their opinions, of course.
