The Patch 2.3 was released November 16th, 2007.

What does this mean for PvP? Specifically from the patch notes:

• Arenas
  • The top ranked team of each battlegroup for each format will receive a new unique title for the end of Season 2 called "Merciless Gladiator".
• Battlegrounds
  • Daily quests have been added targeting a random battleground for that day. Look for Alliance Brigadier Generals and Horde Warbringers near your faction's battlemasters in all major capitals.
  • Dropping the Flag in a battleground will now result in a debuff that will not allow you to pick up the flag again for 3 seconds.
  • Druids who are shapeshifted when they receive the Restoration buff from battlegrounds will now correctly regenerate mana.
  • Players will now be able to cast spells for free in the Battleground before it begins.
  • Players will now be able to cast spells for free for a few seconds after being resurrected by a Spirit Guide in the Battleground.
  • Alterac Valley
    • Additional Warmasters no longer report for duty upon destroying an enemy tower. However, destroying an enemy tower still eliminates the associated opposing Warmaster.
    • All Warmasters are linked to each other and their respective Generals and can no longer be pulled individually.
    • Honor from capturing towers has been increased.
    • All Commanders and Lieutenants have left Alterac Valley in search for other battle opportunities.
    • Players will no longer be sent to their starting tunnels on death unless that team controls no graveyards in the battleground.
    • Many NPCs in Stormpike and Frostwolf holds are no longer elite
    • Bonus Honor in Alterac Valley is now only awarded during the battle for destroying enemy towers and slaying the enemy Captain. Upon conclusion of the battle, bonus honor is also awarded for intact towers, a surviving Captain, and for victory in the battle. The total bonus honor awarded should be similar to the previous total.
    • The Horde and Alliance now have a limited number of reinforcements available in the battle for Alterac Valley. The number of reinforcements available is reduced upon player death, loss of towers, and death of Captain Galvangar or Balinda Stonehearth. In addition, all available reinforcements are lost upon the death of General Drek'Thar or Vanndar Stormpike. If a team is reduced to zero reinforcements, the opposing team wins the battle.
    • Towers and Graveyards in Alterac Valley are now captured in 4 minutes (down from 5).
  • Eye of the Storm
    • The points awarded from capturing the flag in Eye of the Storm is now increase based on the number of bases the capturing team owns.
  • Warsong Gulch, Arathi Basin, Eye of the Storm
    • Additional bonus honor is now awarded upon conclusion of the battle.

No information on exactly when season 3 will start, maybe next week.
