is there any difference betwen wm build 23103 and the new ones 23554, i know that the first one is ms official wm653 and the 23554 is a leaked one, but aint a newer one better ?
They are on 2 different development paths.
23103 is win 6.5.3
23554 is win 6.5.5
23544 and others are considered beta - in development - versions
Newer doesn't mean better - it could have bugs, things left out, etc.
