Blizzard's hotfix notes for 10 and 11 November bring the first real class tuning since launch: Enhancement Shaman takes a big cut, Hunter pets lose some health, Warlock demons get tougher and Affliction's Wrack is reworked. There are also profession, quest and dungeon fixes. These are the ones most players will notice, in our own words. Blizzard's post has every line.

Classes, 10 November

Class What changed
Shaman (Enhancement) Stormstrike 150% → 100% weapon damage, cooldown 6 → 8 s. Maelstrom Weapon now 20% faster casts at every rank, but only 6 to 10 procs a minute. Mental Dexterity gives less attack power from Intellect. See the Enhancement nerf
Hunter Pet health 150% → 115% of normal. Arcane Shot costs 11% of base mana. Beast Mastery's hawk hits about 80% harder. See the pet change
Warlock Imp, Voidwalker, Incubus and Succubus base health up about 15%. Imp Firebolt hits harder at ranks 1 to 4
Warlock (Affliction) Wrack reworked: a 6-second channel with 30% less damage, during which your DoTs tick twice as fast. See the Wrack rework
Druid (Restoration) Nature's Swiftness also makes Wild Growth instant
Shaman Weapon imbues and weapon totems now work at the same time
Warrior (Arms) Sweeping Strikes no longer loses charges when there's no second target

Classes, 11 November

Class What changed
Paladin Judgement is now a ranged attack: it uses ranged hit and no longer triggers melee effects
Paladin (Retribution) Unsealed Fury no longer echoes off Windfury Totem attacks
Druid (Feral) Rend and Tear now works on Pounce's bleed
Hunter Volley no longer triggers procs or keeps channelling after you move
Priest Gnome Priests can use Confounding Flash in Shadowform, and Twilight Focus works in Shadowform
Shaman Flametongue Totem rank 2 works

Where a change moved a spec up or down, our PvE tier list and PvP tier list already reflect it.

Professions

  • Tailoring bags fixed: the Red Mageweave Bag (14 slots), Green and Black Silk Packs (12 slots) and Green and Red Woolen Bags (10 slots) now cost one more bolt of cloth each. See more bag space.
  • Blacksmithing: Coarse Grinding Stones give skill-ups up to 90.
  • Cooking: the Journeyman Campfire Kit needs Cooking 90 to place, down from 140.
  • Enchanting: Lesser Spirit enchants for boots and bracers give Spirit as they should.
  • Engineering: Iron Grenades are cheaper at the vendor.
  • Some crafted armor sells for less to vendors.

Quests and the world

  • Most quests from level 48 up now also reward gold.
  • More Glade Vipers in the Riverglades for "Poison Tips", and more Nightbane worgen in Duskwood for "Worgen in the Woods".
  • Several stuck quests fixed in Feralas, Arathi Highlands and the Western Plaguelands.
  • Riverglades bosses Twilight Enforcer, Executioner Morg and the Twilight Forgemaster hit much less hard.
  • All racial vendor mounts are now bind on pickup.
  • The Item Restoration service is switched off for now while Blizzard looks into a bug.

Earlier fixes are in hotfixes 5 to 9 November. Problems Blizzard hasn't fixed yet are on known issues and hotfixes.
