Patch 4.0.3a

Patch 4.0.3a, "The Shattering", is a pre-Cataclysm content patch that updates the old world in preparation for the expansion's release.
==Re-release==
This patch is the only patch in World of Warcraft history to be re-released. The original US patch on November 22nd was missing a key skin for boats, so users who patched with the ~20MB version were unable to use any boat. Users who patched in the evening of November 22nd were unaffected as Blizzard had added the missing skin to the patch (~130MB). Unfortunately the streaming client couldn't differentiate between the two separate versions, so on November 29th, this issue was resolved by re-releasing the entire patch to the entire US userbase, followed on November 30th to the EU userbase, with additional content (~162MB). This re-release also released a bug fix for users experiencing disconnection issues on entering a new zone.
==The Shattering of Azeroth==
In the frigid wastes of Northrend, the final battle against the merciless Lich King ended in victory for Azeroth's defenders. Upon returning home, veterans of the unforgiving conflict against the Scourge were showered with praise for their valiant sacrifices, while the honorable dead were mourned. Yet as hope flared anew in the wake of the Lich King's fall, Azeroth's native elemental spirits grew confused and erratic, setting off a series of deadly natural disasters. Horde and Alliance leaders scrambled for clues about the troubling state of the world, but nothing could have prepared them for what was to come.
Without warning, the corrupted Dragon Aspect, Deathwing, erupted from the stone heart of Deepholm, the domain of earth within the Elemental Plane. Jagged fissures were torn across the earth, and monstrous waves pummeled coastal regions. From Thousand Needles to the Blasted Lands, the surface of Azeroth was reforged through violent upheavals. Now, the Horde and the Alliance must defend their homes against Deathwing and his minions, burdened by the unsettling fact that the world as they know it has changed... forever.

*Azeroth Shattered
**Deathwing's return has had an immeasurable impact throughout the Eastern Kingdoms and Kalimdor. Players will notice drastically altered terrain, thousands of new quests from levels 1-60, and updated level ranges for some zones to improve the questing flow.
*New Race/Class Combinations
**In the wake of a world on the brink of destruction, members of the Horde and Alliance have taken to new cultures and studies, mastering crafts previously foreign to them. Many existing playable races now have new class combinations. 
*The World of Warcraft: Cataclysm cinematic trailer and login screen have been added to the game.
*Experience required to gain levels 71 through 80 has been reduced by 20%, which increases leveling rate by 25%.

* Due to several talent revisions for select classes, druids, paladins, priests, and shaman have had their talent trees reset.
* The damage and healing done by players from levels 1-79 has been retuned, with the base points of almost all spells and abilities reduced. This was done to bring combat times at low levels to a more reasonable length.

* Healing Rain, Efflorescence, Holy Radiance, Holy Word: Sanctuary now have a diminished effect when healing more than 6 players at once.
* Mortal Strike, Furious Attacks, Wound Poison, Widow Venom, Permafrost (mage talent), Improved Mind Blast, Monstrous Bite, and Legion Strike now reduce healing by 10%, down from 25%.

===Death Knights===
* Death Pact now heals for 25% of maximum health, down from 40%.
