Here are the patch notes, quoted from Kiara on the EQ2 forums.

BATTLEGROUNDS

Battlegrounds are now live in EverQuest II! To access them, simply hit Alt+Z.

GENERAL

Guard levels in Freeport have been slightly adjusted: many level 95 guards remain, but they are no longer blocking access to quest updates for good-aligned players of high level.
Obelisk of Lost Souls: Characters who are high enough level to gray-out the access quests now automatically gain the power to open the doors.
Sata, the Quel’ule faction merchant, now also sells scholar type fuel (candles, coal, and incense).

ITEMS

Elemental Barrier (a unique proc on some PvP gear) has been improved as a proc and now stacks with itself
The PvP proc Mutilation has been changed. Instead of reducing the effectiveness of your target’s heals (thus making it only effective vs healers), it now reduces the effectiveness of all heals on your current target (making it effective vs anyone who is being healed)
Those that completed the quest “The Fleshbound Tome Speaks Again” can now buy the “Flesh Bound Tome” from the city sages in Freeport and Qeynos.
Those that completed the quest “A Crusade to Faydwer” can now buy “The Missing Pages of the Sword Heist Journal – Rebound” from the city sages in Freeport and Qeynos.
Those that completed the quest “Hadden’s Earring” can now buy “Hrath’s Journal” from the city sages in Freeport and Qeynos.
Sentinel’s Fate (and scaled-to-90 TSO dungeons) heroic legendary gear should all have resists now.
Roger Goldie’s Straw Hat should no longer have the “Hooluk in a Hat” effect on it.

QUESTS

Players that decline or delete the quest “Geobot” after completing “Conflict Among the Kobolds” can now regain it by speaking with Watchman Plarg in Steamfont.
Players are no longer being misdirected to search within “The Hole: Outer Vault” for Dartain’s Fortress, while on the quest “The Footsteps of Dartain: Emergence.”
Players on the quest “The Footsteps of Dartain: Experimentation” only need to speak with the spirit once in order to advance the quest.
“Infiltrating the Sanctum: Emissary Kvikz” now recognizes when the player defeats “Sslan’yiz the Animator”.
Alim Dabir in Sundered Frontier now responds for the quest ”Further Research Required” even if you have previously deleted it after completing other quests.
“Justice for Jojo” now updates more reliably at the final stage, and correctly removes quest items from inventory when they are no longer needed.

TRADESKILLS

Incorrect recipe costs on a number of crafted Mark of Manaar equipment items have been corrected.

NEKTULOS

The “guardian mist grinnin” have a higher chance of carrying the kneespikes required for the quest “Ashland Kneespikes.”

VASTY DEEP

Xilaxis the Explorer’s item tables have been corrected and he should always drop loot on both normal and challenge-mode.

Hopefully servers will be up soon, it has been about 3 hours downtime already.

Until next blog post,
