There are 3 numbers that are tossed around quite frequently. 14.1, 1.0, and Pub#.
14.1 is the version of LIVE SWG the SWGEmu project is emulating.
1.0 is the completion of the SWGEmu project, where the ground game is finished and the new play server is opened up.
Pub# is just whatever Publish the SWGEmu project is currently on. There is no set number of Publishes before we reach 1.0.
Up until this announcement, SWGEmu's v1.0 was meant to be an accurate emulation of Live SWG v14.1... so the two could have been considered the same. However, now that we're moving into beta, it appears that our 1.0 will now feature some non-14.1 changes, which is exciting.
Hope this helps.
