Anyone got a loc on where the smithing changes can be checked out? I just looked at the patch history and I can't find anything on it, therefore I have no idea what you guys keep saying about "smithing was nerfed already". I never bothered with it till recently so I'm clueless

Used to be smithing increased at a fair clip. You could grind your way to 100 on iron daggers if you really wanted. I never did. I just killed bandits, some dear, improved the armor and sold it. Maxed out my smithing and all related perks by level 30 and things were still kicking my butt on a fair enough basis to make the game a challenge.
Now crafting skills level based on item value. You want to see a faster increase you have to make more valuable items like jewelry, glass, ebony and the like. Technicaly you could just spam gold rings, but gathering the materials even with the trasmute spell is time consuming, so not really a cheat as far as I'm concerned. Maxing out any of the crafting skills takes deliberate effort. A lot of it.
-edit- the changes were introduced in the 1.6 patch
