Nope, no standalone patches, though the main game installer now shows "1.0.2-277R", which is the latest non-beta release. Just install Galazy*, point it at the game, wait until it's done updating, and uninstall it.
I'm guessing they won't bother throwing a standalone installer together until they have assurances from HBS that it's going to take them a while to release another patch. Anyone knows if they are moving away from patch files altogether? That's another possibility.
*feels pretty appropriate too, what with the crappy download speeds and all
In a world before GaLazy I had to redownload the Wasteland 2 installers three times because there were no standalone patches for the current version, so that's not really new for GOG. It's weird since it got a lot better after WL2. I guess it got worse because of GaLazy.
