1.6 Alchemist Formulas, are they automatically leveled up?

[arenium]

Update 1.6 did away with empower bombs and instead gave levels to the alchemical items.

Does an alchemist automatically know the higher level of a bomb they already know or do they have to take the new level of the item as a new formula either when leveling up or by using a feat, like Inventor?

It seems to me that they would have to relearn the formula when they level up, otherwise they'll learn all the formulas pretty quickly, but I don't seem to see anything that says otherwise.

Higher levels of a formula are indeed separate formulas.

Yeah, as far as I can tell they count separately. So I think this change does mean that maybe alchemists should get another free formula per level or something, because now you have to spend more just to stay current. It's not the biggest problem facing alchemists though.
