So many bugfixes!
For the most part, it's just bugfixes, but ArenaNet has rolled out the newest patch for Guild Wars 2. There's a few balance tweaks too - most notably, the Necromancer's abilities have had a few buffs, such as Spectral Grasp granting 10% life force and Last Gasp removing stun and applying protection, and additionally Mesmer's Phantasmal Warden has been given a recharge timer of five seconds.
The full notes are on the Guild Wars 2 website and forum.
