I didn't realize it was going to get updated so soon, but the versions on that page were at "8.16.5" for the Windows and Linux versions when I sent my email a couple days ago. It also appears the versions for the OSs aren't all updated at the same time (.6 seems to only includes Windows/macOS

I'm reviving an ancient thread, but is Bullseye truly dropping FreeBSD support? Do you have a link to something that shows that? I still see a FreeBSD tarball in their download archive page for the newest version of their tool, which seems to be 8.16.5. - Eric On Thu, Aug 8, 2019 at 12:08 PM
