The PTR 3.0.3 Patch Notes are available. To put it in a nutshell, this patch adds lots of goodies to each class, with barely any nerf.  Glyphs have been updated with favoring changes.  Alchemy elixirs got a bit of a nerf to compensate for class changes. Certain Hunter pets got smacked by the nerf bat.  Read the full patch notes after the break.

World of Warcraft PTR Patch 3.0.3

Racial

  • Shadowmeld: The cooldown will now start on use instead of on break.
  • Devouring Plague: The bonus coefficient has been increased to be on par with other DoT spells. Base damage on ranks 7,8, and 9 decreased to partially compensate for better scaling.
