A new recipe has been added to cooking trainers for making Black Jelly, using several Borean Man 'O War as ingredients. While it looks disgusting, it restores more health and mana than the highest level food.

Several Northrend recipes were given greater skill up ranges to make it easier to reach 450 cooking skill.

Greatly increased the drop rate of enchanting recipes found in pre-Lich King dungeons and raids. (mongoose, etc)

A new (and very rare) special mount can now be caught from Northrend fishing pools. (LOLNICK, assuming this is the turtle)

New fishing dailies are now offered from Marcia Chase in Dalaran City!

The time needed to catch fish has been reduced.

You can now fish anywhere, regardless of skill. Every catch has the potential for fishing skill gains, but you are likely to catch worthless junk in areas that are too difficult for your skill.

You can no longer fail when Mining, Herbing, and Skinning. (lol)

Northrend herbs now yield more herbs on average.
The herbalism requirement for gathering Tiger Lily has been reduced to 375.
The time it takes to gather herbs has been reduced.

Added around 50 new glyph recipes. These new recipes can be obtained from Books of Glyph Mastery found as world drops on Northrend monsters. Reading a Book of Glyph Mastery randomly discovers one of the newly-added recipes.

Glyph icons have been updated so it is easy to distinguish between classes. (t4t)

The Lightweave tailoring enchant now sometimes grants a temporary spell power bonus instead of dealing direct damage to your target. (t4t changing right after i drop tailoring because lightweave is terrible)

New dungeon maps have been added for all Wrath of the Lich King dungeons. (vn)

Class roles (i.e. damage, tanking, healing) have been added to the Looking For Group feature. Class roles will be displayed when sorting through the Looking For More section.Quest and Achievement tracking are now combined in a new Objectives Tracking window. Advanced features can be activated from the Objectives Options panel.

On-Use items will display in the Objectives Tracking when tracking a quest that uses them. No more searching through your bags for that on-use quest item!

Players first entering any dungeon that will result in a lock-out timer will be warned if they are going to be saved to the instance. This warning will include an option to port to the nearest graveyard before being saved. (awesome)

Three new mounts are available from Horde mount vendors, equalizing the number of purchasable normal and epic mounts: the Black Wolf, the White Kodo, and the Black Skeletal Horse (in Orgrimmar, Bloodhoof Village, and Brill respectively). (mount fags)

Badges and Emblems looted off of any dungeon bosses by a member of the party or raid will automatically be given to all eligible party or raid members. Party or raid members must still be inside the instance to receive Badges or Emblems. (lol)

Enemy Unit Frames: This feature is only available while in Arenas, with several options in the Interface Options.

tl;dr
