On the PVP ruleset server the following bonuses have been added:
200% bonus to BP in all classic zones and dungeons.
200% bonus to BP in all NF zones.

200% bonus to XP in all classic zones and dungeons.
200% bonus to BP in the capital cities.

(Note: BP was increased in the capital cities as this is where seals can be turned in that award BPs.)

In addition, fireworks have been enabled above each realms border keeps on the New Frontiers side of the keep to celebrate the anniversary! If you find yourself at the border keeps during the in-game hours of night, look up and be dazzled by the festivities!
