This is part when it has successfull update and after that it resets and shows
File not found(404)
for next available update coded in and you know that previous version updated.
Its just cosmetics but i would not remove it.
Users dont see it, and as for developer it is good information in case you put 0.0.4 version and he still does not find it on server, it gives you a clue that something is wrong (extra space in file name, caps differences etc)
