Blizzard are calling for action once again as they've implemented two changes to the test version of Antiga Shipyard.
According to Blizzard, there aren't significant balance issues at pro and non-pro level but they agree that Zerg and the Zerg match-ups might need tweaking. Hence:
Fungal Growth no longer affects psionic units. This will not only increase the potency of some casters like High Templars and Ghosts, but also helps a large portion of the Protoss' units like Mothership, Dark Templars, Archons, Sentries and Warp prisms.
Raven's Seeker Missile no longer requires upgrade. In a recent interview with Gamespot, Browder suggested that teching to Seeker Missile's is maybe too slow and hard to do. The change's purpose is to present terrans more options when playing late-game TvZ but might also prove useful in mid-game TvP pushes.
All the feedback you might have should go
here.
