v9.2.0.0p1-Beta
This is a beta-release (non-production ready)
This release includes:
- Upstream changes from OpenSSH 9.2, which fixes a number of security bugs.
- Breaking changes - see upstream release notes for more information:
- adds EnableEscapeCommandline to ssh_config, a new option, that controls whether the client-side ~C escape sequence that provides a command-line is available. EnableEscapeCommandline defaults to "no", which disables the ~C escape sequence that was previously enabled by default.
- Security:
- The sftp server will not attempt to add the Mark-of-the-Web (MOTW) for files uploaded from sftp clients, which reverts the behavior added in 9.1. This is on par with scp behavior for file uploads. File download behavior via scp and sftp remains the same as 9.1, with a best effort attempt to add the MOTW. This change was prompted by Community feedback, as discussed in #2029.
- Fixes for #2018 and #2019.
v9.1.0.0p1-Beta
This is a beta-release (non-production ready)
This release includes:

- Breaking changes - see upstream release notes for more information:
- Switches scp from using the legacy scp/rcp protocol to using the sftp protocol by default.
- SetEnv directives in ssh_config and sshd_config are now first-match-wins to match other directives. Previously if an environment variable was multiply specified the last set value would have been used.
- ssh-keygen -A (generate all default host key types) will no longer generate DSA keys.
- Security Fixes:
- adds Mark of the Web (MOTW) to scp/sftp file transfers, when possible.
- Fixes for various reliability issues listed here.
- LibFido2 upgrade to version 1.12.0.
- LibreSSL upgrade to version 3.6.1.
