The file versions are only a guide. I haven't compared them this time, but it has been pretty much the case that every time in the past with a different package version the files are not bit identical despite having the same file versions. I believe the files therefore should be considered later builds of the same versions of files. The differences are most likely quite minor, but if it's later it's most likely still a good thing . There could be minor bug fixes, performance improvements in certain circumstances, or some other change.
