All patch sets from 4.4p1 to 8.1p1 are now available on SourceForge at https://sourceforge.net/projects/hpnssh/. The entire codebase (merged with OpenSSH) is also available as a git repo from https://github.com/rapier1/openssh-portable. The SourceForge location now includes prebuilt binary and source packages for Redhat (7.6p1 – 8.1p1), Debian (7.8p1 for Buster and 8.1p1 for Sid), and gsi-openssh for CentOS 7 (7.6p1).
