Pirates of the Burning Sea will be updated today to v18.104.22.168, aka the Anniversary Update. The update will prepare servers for the third anniversary celebration scheduled to begin on January 22nd. New content has been added, San Juan, Spain's capital city, has been updated, and new pets have been added to Treasure Aisle. In addition, bug fixes, enhancements and improvements have been included for deployment when the patch goes live later today.
Happy Anniversary to Pirates of the Burning Sea! We celebrate our 3rd Anniversary on 1/22/2011. This is quite an achievement and we’ve added some fun new content to celebrate. Look for the Royal Society representative in your starter town or nation’s capital for the mission / mini-games. Completing these will grant you a new coat. For a limited time only, a black cockatoo is available in Treasure Aisle as is a monkey dressed for celebration!
