Here are some precisions posted by Blizzard.
Protoss- The Protoss Phoenix has anti-gravity now and it is great at harassment, especially with more than one Phoenix in a pack. These harassment groups can easily lift workers and other strategic targets like Queens to be taken out while floating in the air.
The Phoenix in the latest build uses energy (4 per second) when casting anti-gravity, thus the same Phoenix is not able to attack the target it is lifting with anti-gravity.
- You can cloak your Mothership with your Dark Pylon's Null Shield.
In this case, the enemy can't see anything in your base without a Detecting unit.
Zerg- Overlord has the Generating Creep ability after Lair and the Transport ability after researching at the Lair.
- Overseer has Detecting ability as passive and Healing ability (by 200 hit points) on the biological unit or structure. and Overseer can spawn the Changeling.
Overseer does not have Nydus Worm spawning ability any more.
- You need the Lair to build Nydus Network. You can mutate your drone into Nydus Network with 150 Mineral and 200 Vespene Gas. From your Nydus Network, you can summon multiple Nydus Worms at any place on the creep and each Nydus Worm cost 100 Mineral and 10 seconds build time. Units can enter a Nydus Worm or Nydus Network and exit through any other Nydus Worm or Nydus Network. Units are coming out of the Nydus Worm/Nydus Network one-by-one and they come out in the same order they entered in. You can't move Nydus Worms once you summon them.
- You can build Creep Tumor from the Queen only on the creep to expand it.
Terran- In the current build, you can train SCVs at all three regardless of the upgrade.
You can load SCVs up to 5 into Command Center and Planetary Fortress.
Command Center and Orbital Command can be lifted off, but Planetary Fortress can't be lifted off.
You can also load and unload SCVs while your Command Center is lifted off.
No, you can't build SCVs while lifted off
No, you can't downgrade the Command Center back.
