Galaxy acts like a wrapper for the website. Steam does the same thing.

But yeah, the patchnotes are a bit slow. I'm guessing it's the gamestudios themself that adds the patchsnotes. Correct me if I'm wrong... :)

Hello Games is by the way very slow with adding the latest patchnotes on the No Mans Sky website.

See the thread at the top of the first page titled Changelog. I cut and pasted the notes that HG allowed Steam users to receive.

I think it may be a mixture of both (like if the devs send the patch notes with the new build, then GOG would input it)... I emailed Supergiant games to ask if they'd please bring all their games on GOG up-to-date, they were incredibly awesome and abliged quite quickly to boot, but I'm pretty certain (in my talks with them) that they just sent everything to GOG and then they were done Appreciate the effort there... just stinks that it became a multi-page discussion instead of just the patch notes (not your fault)
