Class Specific Changes

Barbarian
Body Bludgeon: Pre-Req Removed, It only requires a successful maintained grapple check to begin murder, they can still try to escape, they do not have to be conscious.

Guarded Stance: Bonus increases at 3rd and every 3 levels thereafter, while in this stance you reduce the penalty to AC from rage by 2.

Check with me before taking rage powers, many are getting updated.

Magus
Arcane Accuracy: The bonus from this ability is capped at half your level (rounded up) and this swift action may be combined with the swift action from Arcane Strike.

Rogues
Using Unchained Rogue (Except Rogues Edge and skill unlocks).
All Rogues gain an additional 2 skill points a level over other classes
Sneak Attack can apply at any range though other limitations still matter.
Finesse Training becomes Rogue Training
Every Rogue gains a new personal archetype that fills in some other lackluster levels (2, 7, 9, 13, 17)
Every Rogue additionally chooses a Rogue Discipline that replaces rogue’s edge
Minor Magic (Rogue Talent)
Major Magic (Rogue Talent)

Sorcerer
Instead of giving a bonus class skill, a sorcerer gains a free rank in the skill for every level of sorcerer he has. It is otherwise treated as normal for Eldritch Heritage Requirements and the like.

Bonus Spells from your bloodline are instead gained a level earlier than normal.
