== Platform ==
The [[operating system]]s or [[virtual machine]]s the SSH clients are designed to run on without [[emulator|emulation]] include several possibilities:

 <!--* ''No'' indicates that it does not exist or was never released.-->
* ''Partial'' indicates that while it works, the client lacks important functionality compared to versions for other OSs but may still be under development.
 <!--* ''Beta'' indicates that while a version is fully functional and has been released, it is still in development (e.g. for stability).
* ''Yes'' indicates that it has been officially released in a fully functional, stable version.
* ''Dropped'' indicates that while the client works, new versions are no longer being released for the indicated OS; the number in parentheses is the last known stable version which was officially released for that OS.
* ''Included'' indicates that the client comes pre-packaged with or has been integrated into the operating system.-->

The list is not exhaustive, but rather reflects the most common platforms today.
