The Warhammer Online team has announced that v1.4.5 has been deployed. The Warhammer Herald has a highlights list that goes into detail about the most significant changes.

• Relics: Players can search tunnels under fortresses to find arcane relics.
• Fortresses have, because of the new relics, become "strategic footholds for realms to invade and defend.
• Grovod Cavern has returned to the game. Players duke it out underground.
• Scenario Shake Up: Some scenarios are headed into the vault for now while others have had a tier change and yet others are returning to the game with some minor changes. All of the alterations to the scenarios were made in response to player feedback.
