For the sake of people in this thread who don't have access to the blessings:
Air - unchanged, but looks fairly solid to me to begin with. Point Blank Master seems good for a level 1 ability, and fly with upside seems like an ability I'd use a lot.
Animal - Also unchanged.
Artifice - Crafter's Wrath now ignores DR or hardness when attacking constructs or objects. Transfer Magic appears unchanged.
Chaos - Anarchic Strike is no longer limited to melee weapons. Battle Companion is unchanged, but Summon Monster is considered to be one of the strongest spells in the game, and you can summon as a standard action, without dismissing your best class feature like a Summoner.
Charm - Unchanged.
Community - Communal Aid is unchanged. Arrow Deflection was entirely replaced by Fight as One, which was previewed on the blog. And awesome.
Darkness - Enshrouding Darkness is unchanged, but still concealment against anything without blindsight. Darkened Vision went from a melee touch attack to one target within 30' (Will negates).
Death - Unchanged.
Destruction - Destructive Attacks was clarified such that it only functions on weapon damage rolls, but otherwise unchanged. Notably, Heart of Carnage does not specify it doesn't stack with Critical Focus or fortification armor.
Earth - Acid Strike is no longer limited to melee weapons. Armor of Earth no longer stacks with other DR/-, but increases by 1 for every 2 warpriest levels (capped at DR 5/- at 18th).
Evil - See Chaos, replacing Anarchic Strike with Unholy Strike.
Fire - Fire Strike is no longer limited to melee weapons. Armor of Flames is unchanged.
Glory - Unchanged.
Good - See Chaos, replacing Anarchic Strike with Holy Strike.
Healing - Selfish Healer has been replaced by Powerful Healing, which allows you to swift action Empower any cure spell you cast. Fast Healing is unchanged.
Knowledge - Lore Keeper is unchanged. Monster Lore is now a swift action, but now can be triggered through use of Lore Keeper.
Law - See Chaos, replacing Anarchic Strike with Axiomatic Strike.
Liberation - Unchanged.
Luck - Unlucky Presence has been replaced with Lucky Presence, which allows an ally to roll the d20 twice and take the better result on any 1 ability check, attack roll, saving throw, or skill check. The blessing lasts until used. Unlucky Enemy remains unchanged.
Madness - Unchanged.
Magic - Also unchanged.
Nobility - Inspiring Word only affects one of attack rolls, ability checks, saving throws, or skill checks (warpriest's choice) but now lasts 1 minute instead of 1/2 warpriest level rounds. Lead by Example is unchanged.
Plant - the unnamed minor blessing is now Creeping Vines. Battle Companion is Battle Companion (and therefore unchanged).
Protection - Increased Defense now scales every 10 levels instead of every 5, but is now a sacred bonus to both AC and saving throws. Aura of Protection no longer grants a deflection bonus to AC, but the energy resistance to acid, cold, electricity, fire, and sonic damage is doubled.
Repose - Unchanged.
Rune - Unchanged.
Strength - Strength Surge is unchanged. Strength of Will has been clarified to allow you to add STR to saves against effects that would entangle, paralyze, or stagger you.
Sun - Blinding Strike appears to no longer be a melee touch attack, but I can't find a range. Bane of Undead has been changed to Cleansing Fire, and can add either flaming or undead bane to the weapon - both if you expend two uses of your blessings ability.
Travel - Agile Feet now specifies it even counters difficult terrain created by magical effects, and Dimensional Hop now lets you teleport in 20' increments. Additionally, each ally you bring with you only costs 1 use of blessing, regardless of distance traveled.
Trickery - Copycat has been renamed Double, but otherwise unchanged.
War - Unchanged. Again, note that Battle Lust does not specify it doesn't stack with Critical Focus or other similar effects.
Water - See Fire, replace Fire Strike with Ice Strike and Armor of Fire with Armor of Ice.
Weather - See Fire, replace Fire Strike with Storm Strike and Armor of Fire with Wind Barrier.
