Caster level, Stack?

[Flameheart]

I appoligice for bad english, and ofc. if the question has already been answered, but i could not find it anywhere.

A friend of mine tole me, that if i get a " +x caster level ", i do not add them together, but takes the higest bonus i get.

Now, does that meen that lets say,
Varisian Tattoo: "Select a school of magic (other than divination) in which you have Spell Focus—you cast spells from this school at +1 caster level. Additionally, you gain a single spell-like ability usable up to three times per day."

AND

Gifted Adept: " Pick one spell when you choose this trait. Whenever you cast that spell, its effects manifest at +1 caster level."

Does not stack? so i would have wasted my Gifted Adept it i choose a spell of the samme school that i have the varisian tattoo?

Those would stack: but they would only let you cast spells more effectively, for example your fireball would be 8d6 instead of 6d6.

Things like wizard and sorcerer levels on the other hand don't stack at all. Thats probably what your friend was thinking of.

I know that one spellcaster class does not support the other with caster levels, But he said something about they are deference bonusses and therefore does not stack? he mentioned that paizo changed the caster level bonusses cuz otherwise a sorc lvl 1 could make a burning hands with 4-5d4 dmg

Your friend is incorrect. I would bet he can not show you where it says they do not stack.

Isn´t it possible that paizo released a statement, or "update" that they changed it?

Those "updates", also known as errata, are very quickly reflected in the online prd. Thus, if it is not in the prd, then it could only have been updated very very recently.

It would have been in one of the errata documents even if they went back and changed it again.
It is not in any of them, nor is it in the FAQ section.
