Software developers, why move user interface objects around in an update?

I may be just an old man yelling at the clouds here, but serious question.

Why move buttons around during an update? Now I'm not talking about full scale UI changes, I'm taking relatively minor stuff. I have to use a specific app for my work time clock, and one of the functions I have to do everyday is verify the previous days log. That app was updated yesterday.

They moved the verify button from the right side of the screen to the left side. It's been on the right side for years. Even through hardware changes.

Why? Is it just because some mid level manager thinks if things don't change visually nothing happened?

Is it to mess with people who memorize locations of often used things so they don't need vision to use those things?
