--User Interface

Raid UI has been significantly improved. You can now open the raid UI and drag the name of a class to your gamefield to have a listing of all players of that class be displayed on the game field. Likewise you can drag a group name to your playfield to have the players in that group displayed on your gamefield. In either case the display will show the health, mana and limited buffs or debuffs on each player in the group or class and you can click on a player listed this way to target that player. You can then right-click on the class or group UI element to make some modifications to how the UI displays or to remove the UI element.
If you cycle through targets with the Tab key, manually select a different target using another method, then quickly hit Tab again, your last Tab-selected target will be re-selected and you can continue Tab-selecting where you left off. Clearing your target will restart the Tab selection process.
Items on the action bar now remain there even after they are consumed.
If you shift-click on an item link while you are entering chat text, the item link will now be pasted into your text.
Mail recipient auto-completion will now use names from your guild as well as your friends list.
Hitting Escape will now cancel ranged weapon auto-shots.
The pet UI will now be greyed out while you are mounted to reflect the fact that you can't command your pet.
NPCs which give dishonorable kills have the rank of Civilian and show up with a white title background in the targeting frame.

--World Environment

Flight Paths
Added a Wind Rider Master to Camp Taurajo in The Barrens.
New Horde Flight Paths --
Camp Taurajo in The Barrens <-> Crossroads in The Barrens
Camp Taurajo in The Barrens <-> Thunder Bluff in Mulgore
Camp Taurajo in The Barrens <-> Freewind Post in Thousand Needles
Fixed several problems with the flight path from Undercity to Hammerfall while passing through the Ruins of Andorhal.
Fixed some problems with the Ironforge to Stormwind flight path.
The Darkshire <-> Booty Bay flight paths no longer fly over the Gurubashi Arena in Stranglethorn Vale, and therefore no longer flag fliers as being in Free-for-All PvP. Also, they should no longer fly through the zeppelins coming in and out of the Grom'gol Base Camp.
Graveyards
Feralas, Durotar, Mulgore, Darnassus, Tirisfal Glades (excluding the Bulwark graveyard), Elwynn Forest & the Eastern Plaguelands have now all been converted over to the new graveyard system. The system will place your character's spirit at the closest allowed graveyard in the zone. For example, an Alliance character dying closer to the new Darnassus graveyard, detailed below, will use that graveyard rather than the one located at Dolanaar. Starting area graveyards are still reserved exclusively for characters of similar faction that die within their confines. For example, the spirit of a Horde character dying right outside of Deathknell will not use Deathknell graveyard, but will instead go to the next closest Tirisfal Glades graveyard.
A Horde-only graveyard has been added in the northern section of Durotar, just to the south of Orgrimmar. In addition to serving northern Durotar, Horde characters dying in Orgrimmar, The Hall of Legends and Ragefire Chasm will use this new graveyard. Alliance characters dying in Durotar will continue to only use the Razor Hill graveyard.
A Horde-only graveyard has been placed at the northern base of Thunder Bluff in Mulgore. Horde characters dying in Thunder Bluff will also use this new graveyard. Alliance characters dying in Mulgore will continue to only use the graveyard at Bloodhoof Village.
An Alliance-only graveyard has been added at the eastern end of Darnassus. Alliance characters dying in Darnassus will use this new graveyard. Horde characters dying on Teldrassil will still only be able to use the graveyard at Dolanaar.
An Alliance-only graveyard has been added just outside of Ironforge, around the side of the mountain. It is only for use by Alliance characters that die inside Ironforge and in the Gates of Ironforge sub-area of Dun Morogh. Horde characters dying therein will continue to only use the Kharanos graveyard.
The Ruins of Lordaeron above Undercity now has a Horde-only graveyard. Horde characters dying inside the Undercity will use this new graveyard. Alliance characters will continue to solely use the Faol's Rest graveyard.
A neutral graveyard has been added at the Eastvale Logging Camp in Elwynn Forest. The graveyard at Goldshire is now for use by the Alliance exclusively. Horde characters dying in Elwynn Forest and its sub-areas, as well as in Stormwind, The Stockade and the Deeprun Tram, will have their spirits travel to the new graveyard at the Eastvale Logging Camp.
A neutral graveyard has been added on the island of Caer Darrow in Western Plaguelands. It will serve characters who die on Caer Darrow and in Scholomance.
A neutral graveyard has been added in the Eastern Plaguelands near the northwestern shore of Blackwood Lake. Characters that die in The Fungal Vale will continue to use the Darrowshire graveyard due to the mountains between it and the new graveyard. Additionally, characters dying in Stratholme will now use the new Blackwood Lake graveyard.
A neutral graveyard has been added in Feralas, just to the southwest of Dire Maul. Characters dying in Dire Maul will use this new graveyard.
Darkmoon Cards have been seen dropping from high level Humanoids around the world. Collect a set of them and bring them to the Darkmoon Faire when it is in town!
