Blizzard is working on Patch 3.3.3, which is currently on the PTR. Here are some of the class changes from the official patch notes:

Classes: General

• Several raid buffs have had their ranges increased to 100 yards, up from 45 yards, to prevent select buffs from repeatedly getting applied and removed during highly mobile encounters. Some buffs, such as paladin auras, totems, shouts and Blood Pact are intentionally meant to have shorter ranges and remain unchanged.

Death Knights

• Icy Touch: This ability now causes a very high amount of threat while the death knight is in Frost Presence.
• Chains of Ice: The ability now innately applies Frost Fever to a target.
• Rune of Razorice: Now stacks 5 stacks of 2% Frost Vulnerability instead of 10 stacks of 1% Frost Vulnerability. Proc chance changed to 100%.
• Talents
  • Blood
    • Abomination's Might: This effect is now passive instead of being a proc on certain strikes. Rank 1 is 5% attack power and Rank 2 is 10% attack power. The self strength buff remains unchanged.
    • Will of the Necropolis: There is no longer a cooldown on the frequency at which this talent can be activated. In addition, this ability can now also be triggered by damage which deals less than 5% of your health.
  • Frost
    • Endless Winter: No longer causes Frost Fever to be applied by Chains of Ice, but instead grants 2/4% strength.
    • Icy Talons: The personal haste benefit provided by this talent is no longer exclusive with other sources of melee haste. This will allow death knights to always swing 4/6/12/16/20% faster when Frost Fever is applied. Windfury Totem and the party/raid component of Improved Icy Talons still do not stack.
    • Improved Icy Talons: This effect is now passive instead of being a proc. The self haste buff remains unchanged.
    • Nerves of Cold Steel: Now increases off-hand damage by 8/16/25%, up from 5/10/15%.
    • Unbreakable Armor: The amount of strength granted is now 20%, up from 10%.
  • Unholy
    • Scourge Strike: Now deals 70% weapon damage, plus 12% of physical damage done as shadow damage for each of the death knight's diseases on the target. The net result should be larger strikes with no diseases present, while maximum damage with all diseases applied to the target should stay the same.
    • Unholy Blight: In addition to its previous effects, this talent now also prevents diseases from being dispelled from victims afflicted by Unholy Blight.

    • Combustion: The cooldown on this spell is now 2 minutes, down from 3 minutes.
