By that diff and judging by eye 5.1.2 vs 5.2.0 filelist matches quite substantially (md5 sums are different ofcourse).
Differences in the md5sum (or any hash sum) of the file does not indicate functional differences.
Files contain things that will depend on build date and compiler used.
There are various ways to check if two files have the same code (which still leaves open the question of different code that is functionally the same).
Perhaps the simplest is to use objdump -O binary -J .text ....
Other options as desired, and then compare the resultant binary.
