I'm having trouble determining the minimum Windows version supported by #LibreSSL. Is Win7 supported?
@lattera We've succesfully build LibreSSL on Windows (7, x64) - might have been months, for an internal test (exploit development). The changelog for LibreSSL 2.7.0 mentions Vista (or later) at https://github.com/libressl-portable/portable/blob/master/ChangeLog#L1497 - should still work despite the current version at 3.5.3.

@lattera support for Windows 7 ended 2020...
Seeing that OpenSSH still uses LibreSSL 3.0.2
@brnrd @lattera I think you might be preaching to the choir 
@h3artbl33d @brnrd Microsoft ended support for Win7. Security companies, unfortunately, have to pick up the slack and offer support. I'm in that boat.

@lattera @brnrd I have had quite interesting discussions on this matter. Although extremely undesirable, there are organisations that are relying on legacy code that simply can't run on more recent versions. And even me unable to phantom that, doesn't make it go away.

Likewise, the Tokyo police lost PII on 38 citizens in 2021 -- that was stored on floppy disks 

@lattera @h3artbl33d poor man :'(
I do recall the project lost interest in Windows builds at some point.
Still surprises me to see Win10/11 shipping such old version in OpenSSH

@lattera "LibreSSL also supports the following Windows environments:

Microsoft Windows (Windows 7 / Windows Server 2008r2 or later, x86 and x64)"
