As there has been no official errata released yet, Ethan's giving it to us in bits and pieces on the forums. Also, the Lodge of Cerberus rite was left out of Lodges, so Aaron Demski-Bowden was nice enough to give it to us. I'll post more of them as they're presented.

Combat
Consistent with rules for Gauru form and animals (such as dogs), the Urshal and Urham forms gain a +2 bonus to bite attacks.

Gifts
Death Grip: Under the second paragraph under Death Grip (pg. 116), replace with: "A werewolf in Gauru, Urshul or Urhan form can normally stage a bite attack without first initiating a grapple on a target (see p. 171). By use of this Gift and establishing a grapple on a target, however, a werewolf can inflict truly horrific harm. Once a hold is achieved and maintained, the character may spend an Essence point to activate this Gift. The character gains an additional six dice to Strength + Brawl rolls made to overpower the opponent. If the werewolf chooses to inflict damage, the damage is lethal rather than bashing. The victim's ability to break the werewolf's hold is also diminished. The roll made for his next effort to break free or perform an overpowering maneuver of his own suffers a -2 penalty. A werewolf can use this Gift only in Urhan, Urshul or Gauru form. His jaws in Hishu and Dalu form are too small and imperfectly shaped to afford the proper purchase."
Death Grip costs 1 Essence per grapple, requires no roll, and the Roll Results section of the Gift mechanics is disregarded.
Primal Form: Add the following sentence to the last paragraph under Success for Primal Form (pg. 130): "The mental state of Primal Form is not considered the Rage of Gauru form, and cannot be affected by powers that affect Rage such as the Rage Gift list."

Typos and Editing FUBARs
Totem Traits: Despite what the sidebar says, the mechanics for calculating a totem spirit's Willpower and Initiative should be brought in line with the spirit rules in the Appendix. Change the last paragraph of the sidebar to begin "Record Willpower (Power + Resistance), Essence (15), Initiative (Finesse + Resistance), Speed..."
Last sentence on pg. 196: "...they are less concerned with a werewolf's innate morality than the Ralunim are."
Fourth paragraph of pg. 202, change third sentence to "When the year is over, the Uratha is sent into the spirit wilds..."
On pg. 205, the Blessing of Vigor fetish is referred to as "Cub's Vigor" in the text. Revise the third sentence accordingly.
Pg. 234, second column, second paragraph: Replace the word "engum" in the last sentence with "totem."
Pg. 278, second column, fourth paragraph: Remove "Balm" from the list of Gifts appropriate for conversion.
Pg. 290, second column, second paragraph: Change to "When he and his packmates returned to the Rockies, he arranged a gathering at the..."
No, the Shadow of Smoke and Fire (pg. 308) aren't a hidden Easter Egg pack of survivors from Werewolf: The Apocalypse. Change their auspices accordingly: "...the other members of the pack include Chilling Murmur of Laughter (Irraka), Furious Spark of Inferno (Rahu) and Profound Weight of Seasons (Ithaeur)."

New Rite: Speak With the Guardian (●●)
This is the ritual performed at a werewolf's initiation into the lodge, when Cerberus reads his heart to see if the Uratha is truly dedicated. It is also the rite used when a lodge member needs to contact his totem for guidance. When performed, the ritual opens a spiritual link to Cerberus and the ritemaster is gripped by sudden possession as the totem's awareness enters his body. It is a shallow link with no real access to Cerberus' own mind, but even a bare whisper of the great spirits awareness is enough to allow for telepathic communication. The werewolf can ask three questions of his totem, which Cerberus will answer to the best of his knowledge. In addition to his vast knowledge of the Shadow and the general lore of an ancient spirit, Cerberus has the ability to discern the location of any ghosts within a mile radius of any werewolf of the lodge. Also of note, Cerberus can inform the ritemaster of any falsehoods spoken to the werewolf while the Uratha is under the power of this rite.
A werewolf performing this ritual is physically affected by the closeness of his totem. His eyes milk over completely white, though this does not ruin his vision. The ritemaster speaks with Cerberus' voice, which is a crackling whisper that sounds like a burning funeral pyre. Also, werewolves with a Willpower of less than 9 are unable to suppress severe trembling throughout their body, which is painless but definitely unnerving to both the ritemaster and any onlookers.
Performing the Rite: The rite is performed similarly to the Rite: Call Gaffling. It is only a fraction of Cerberus' great awareness that answers the summoning and he is a spirit that is much less bitter about being called than many other Shadow-dwellers. The Chiminage must be proof of a recent success against something that threatened the veil between the living and dead. Every time this rite is used more than once per lunar cycle, the ritemaster suffers 5 levels of Lethal damage from convulsions and internal bleeding.
Dice Pool: Harmony (versus 7)
Action: Extended (20 successes needed; each roll represents one minute); never contested.

Roll Results
Dramatic Failure: All accumulated successes are lost; the ritemaster must begin again.
Failure: No successes are added.
Success: Cerberus enters the ritemaster's body when the required successes are gathered. The totem can maintain this link even when he is otherwise occupied; such is the minute amount of attention it requires on his behalf.
Exceptional Success: None, beyond the extra successes gained.
