OK, doing this when I'm awake worked much better. The reason this failed yesterday sat in front of the keyboard.

All binaries are on the server in http://subsurface-divelog.org/downloads/ as well as in the distro repos.
I'll write the announcement in a couple of hours, I'd appreciate if someone else could test at least the Mac binary (but the Windows binary and AppImage could use some testing, too, of course).
