What does GA, GA refresh 1, GA refresh 2 mean?

Question

I am getting ready to update a standalone R310 and 3 R710's to unleashed.  I see three available firmwares, labeled GA, GA refresh 1, and GA refresh 2.  What is GA?  Which one should I use?

Currently running 
			104.0.0.0.1347 on the R310, it is deployed and functional in the location it's being deployed in.  I am planning on adding 3 R710's and wanted to go to the unleashed platform.

I agree, I see the light now, just confused a little with the naming.  by version number the one labeled refresh 1 is newer than refresh 2, but I see that refresh 2 file is of the 200.6.x.x.x flavor.

For an Unleashed network to setup correctly (any version), the APs look for a local DHCP server and def-gw.
Can you try setting up in the actual location/network you plan to use the APs?
When your network is setup, any version, and all APs recognized, you can do the Admin upgrade if/when there's Internet access.
