OpenSSH updated to version 9.9

All Render services now use OpenSSH version 9.9 to manage SSH connections. Services previously used version 8.9.

If you initiate SSH connections from your service, this upgrade includes one change that might affect those connections. From the OpenSSH release notes:

"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."

If you use the SetEnv directive in your service's SSH configuration, make sure you don't set the same environment variable multiple times to avoid unexpected behavior.

Learn more about using SSH on Render in the documentation.
