       <li>This release switches <a href=https://man.openbsd.org/scp.1>scp(1)</a>
           from using the legacy scp/rcp protocol
           to using the SFTP protocol by default.<br>
           Legacy scp/rcp performs wildcard expansion of remote filenames (e.g.
           "scp host:* .") through the remote shell. This has the side effect of
           requiring double quoting of shell meta-characters in file names
           included on <a href=https://man.openbsd.org/scp.1>scp(1)</a>
           command-lines, otherwise they could be interpreted
           as shell commands on the remote side.<br>
           This creates one area of potential incompatibility:
           <a href=https://man.openbsd.org/scp.1>scp(1)</a> when using
           the SFTP protocol no longer requires this finicky and brittle quoting,
           and attempts to use it may cause transfers to fail. We consider the
           removal of the need for double-quoting shell characters in file names
           to be a benefit and do not intend to introduce bug-compatibility for
           legacy scp/rcp in <a href=https://man.openbsd.org/scp.1>scp(1)</a>
           when using the SFTP protocol.<br>
           Another area of potential incompatibility relates to the use of remote
           paths relative to other user's home directories, for example -
           "scp host:~user/file /tmp". The SFTP protocol has no native way to
           expand a ~user path. However,
           <a href=https://man.openbsd.org/sftp-server.8>sftp-server(8)</a>
           in OpenSSH 8.7 and later support a protocol extension
           "expand-path@openssh.com" to support this.<br>
           In case of incompatibility, the
           <a href=https://man.openbsd.org/scp.1>scp(1)</a> client may be instructed to use
           the legacy scp/rcp using the -O flag.
