StarCraft 2 Beta Patch 17 has just been released... It looks like Terran early game gets a bonus and a nerf with the Barracks, Bunker and Reaper coming faster but the Hellion getting a slight range nerf (not too impactful really). Other changes are negligible. Good gaming to you....
Here are the changes:
StarCraft II Beta – Patch 17 (version 0.20.0.16036)
Many of the following bug fixes were intended for internal testing only, and are now being reverted.
250mm Strike Cannons can no longer deal damage to hidden targets.
