Mac: https://subsurface-divelog.org/downloads/Subsurface-4.6.0.dmg

Linux: A generic AppImage is available for download as Subsurface-4.6.0-x86_64.AppImage. Download this file, make it executable

chmod +x Subsurface-4.6.0-x86_64.AppImage and then simply run this file.

Linux: Ubuntu: Add ppa:subsurface/subsurface to your software sources; the .deb files in that PPA can also be installed on sufficiently current versions Debian and LinuxMint; see the Downloads page and use http://ppa.launchpad.net/subsurface/subsurface/ubuntu to get our latest release version.

Linux: openSUSE / Fedora: go to our open build service release page

Please post questions of problems in the User Forum or file a bug in our Bug Tracker. And as a side note, after too many problems with our old bugtracker, we just switched to using issues on GitHub, so please follow the link above, not the old link to trac you may have bookmarked previously.
