Forbearance
The duration has been lowered to 1 minute, down from 2.
Lay on Hands now causes Forbearance on the target. It used to only cause it when cast on the paladin.
This was an old design from when Divine Protection caused Forbearance and the paladin didn't want to prevent a tank from using their defensive cooldown.
Lay on Hands cannot be a critical effect and will not be affected by most abilities which modify healing (such as Beacon of Light).
Since only Divine Shield, Lay on Hands and Hand of Protection cause Forbearance, the tooltips have been adjusted to better explain the mechanic.
Holy Wrath no longer counts nearby critters when dividing damage among its targets.
Seal of Truth: All single target attacks (including Judgement, Hammer of Wrath, Exorcism, and Templar's Verdict) can now trigger this seal.

Holy
Protector of the Innocent heals for 30% less.

Protection
Vindication no longer allows Hammer of Justice to interrupt stun-immune targets. With Rebuke baseline, this functionality is no longer necessary.

Retribution
Act of Sacrifice will no longer cause Cleanse to remove movement impairing effects from vehicles the paladin is riding.
