"What changed" doesn't match file versions?

Can anyone tell me why the build numbers of the software don’t match the build posted on the “What changed” screen? Build 1746 is not in the log nor is 1752/1754

Later builds have bug fixes of previous builds, or some change that most users won’t ever see. Flavio doesn’t update the What’s New page unless there is a new feature or a very noteworth change. Most bug fixes don’t make the bar to be listed separately.
