Update schedule for Windows' OpenSSH

Hello everyone!

I was looking at Windows OpenSSH that can be installed in Settings under System -> Optional Features -> OpenSSH.

The version of SSH that is installed by Windows this way is 8.6p1 (which was released just under 3 years ago). The latest OpenSSH for Windows available on the GitHub repository is 9.5p1.

I was wondering what the update schedule is for OpenSSH for Windows via Windows Update. I have the following questions specifically:

1. On what schedule does Microsoft update this feature? Is it ever updated?
2. Are security fixes released in the past 3 years included in the OpenSSH that is installed by Windows? Based purely on the version numbers described above, it seems like this OpenSSH distribution has not been updated in the past 3 years: from a security perspective, this seems problematic.

I would be grateful for any information you may have!

Thanks!
