This is a pre-release (non-production ready)

Regressions

• #1164 - scp and sftp won't work if OpenSSH is installed in "Program Files" or any directory with a white space.
  • Work around - install in a path with no white space - ex. c:\openssh
• #1165 - SCP fails when using bash as alternative shell

Note

• This release introduces new rules for specifying user/group based configuration rules for domain principals - these should now adhere to NameSamCompatible format. For more info refer sshd_config manual.

This release includes

• OpenSSH 7.7 changes from upstream.
