Effectively immediately, Gallia is now open for trade.
a.Gallian freighters and transports can move outside Gallia.
b.Gallian faction ID'd ships (non-military, pirate or police factions) can move outside Gallia (this means that the ships in a. above can have escorts.)
c.Anyone can enter Gallia to buy or sell goods.
Time to move things forward. Make some deals. Any potential rules issues or other problems should be posted here.
No where in a, b, or c does it state Gallic civilian tech can leave Gallia. If the admins had intended on Gallia civilian tech leaving Gallia, there would be a line stating so.
It might happen in 4.86, but from what the admins have said, the answer is no.
