Why doesn't patch notes include weapon buffs / nerfs ?

I have noticed the SCAR - light got buffed and yet again with a silent patch, now it does more damage and can 1 shot to the head at mid range.

here is a list of some weapons which got changed ( some changes happened long ago but still worth mentioning )

- Anaconda series got increased fire-rate
-Mauser M1896 got increased delay between burst-fire
- katana got increase in movement speed while holding the right click
-M4A1-S series got a slight damage buff ( very long ago around 2015 )

a short list but that's what I managed to notice.

So please include weapon changes within the patch notes , it would be really helpful.
