Has anybody noticed some changes to the crafting recipes, except for the one noticed in the patch notes?

Regarding that it seems the necessary tenebrium skill increases as the item level of the weapon increase. For instance I managed to add tenebrium damage to an item level 1 weapon with only 1 in tenebrium. For a item level 19 weapon I needed tenebrium 4 (I actually do not know if tenebrium 3 is good enough, but I know that tenebrium 2 is too low). Need to test a bit more.
