Design and Goals
Whonix ™ is a complete operating system. It consists of two virtual machines -- Whonix-Gateway ™ and Whonix-Workstation ™ -- which are designed to be used on a host operating system (OS). The host OS supporting Whonix ™ is usually the one installed on the user's computer, but OSes installed on external drives will also work. Users choose the preferred Whonix ™ configuration and may use either a Type I hypervisor (Qubes-Whonix ™), or a Type II hypervisor like KVM and Virtualbox.
Security by Isolation
Whonix ™ is divided into two VMs: Whonix-Workstation ™ for work activities and Whonix-Gateway ™ to enforce all Internet traffic through the Tor network.  This security by isolation configuration averts many threats posed by malware, misbehaving applications, and user error.

Online Anonymity via Tor
Whonix ™ relies on the Tor network to protect a user's anonymity online; all connections are forced through Tor or otherwise blocked. Tor helps to protect users by bouncing communications around a distributed network of relays run by volunteers all around the world. Without advanced, end-to-end, netflow correlation attacks, anybody watching a user's Internet connection cannot easily determine the sites visited, and those sites cannot learn the user's physical location.

Based on Debian
In simple terms, Whonix ™ is just a collection of configuration files and scripts. Whonix ™ is not a stripped down version of Debian; anything possible in "vanilla" Debian GNU/Linux can be replicated in Whonix ™. Likewise, most problems and questions can be solved in the same way. For example: "How do I install xrandr on Whonix ™?" -- "The same way as in Debian". Whonix ™ does not break anything, limit functionality, or prevent installation of compatible software.
Each Whonix ™ release is based on a particular version of Debian:
|Whonix ™ version||Debian Version||Debian Codename|
|Whonix ™ 188.8.131.52.9||10||buster [archive]|
Users can manually check the Whonix ™ version at any time by following this step.
Note that Whonix ™ does not have a fixed release schedule. A new stable release only becomes available when it is deemed ready. Interested users can query the Whonix ™ phabricator manifest [archive]  and release notes to track developer progress. Stay Tuned.
New Debian Release
One month after a new stable version of Debian is released, Whonix ™ VMs may no longer be supported on any older version of Debian. All users need to upgrade the Debian platform promptly after the deprecation notice in order to use Whonix ™ safely.
New Whonix ™ Release
One month after a new stable version of Whonix is released, older versions will no longer be supported. All users need to upgrade the Whonix ™ platform promptly in order to remain safe.
The deprecation notice is provided at least one month in advance and posted in the Whonix ™ News forum [archive]. Stay Tuned! All users need to upgrade the respective platform promptly in order to remain safe. 
Debian-based and Other Hosts
As per Debian Hosts.
The support schedule is mostly undefined at present, but likely to mirror Debian Hosts.
Whonix ™ is an advanced feature in Qubes OS. Those who wish to use it must stay reasonably close to the cutting edge by upgrading to new stable versions of Qubes OS and Whonix ™ TemplateVMs within a month of their respective releases. To be precise:
- One month after a new stable version of Qubes OS is released, Whonix ™ TemplateVMs will no longer be supported on any older version of Qubes OS. This means that users who wish to continue using Whonix ™ TemplateVMs on Qubes must always upgrade to the latest stable Qubes OS version within one month of its release.
- One month after new stable versions of Whonix ™ TemplateVMs are released, older versions of Whonix ™ TemplateVMs will no longer be supported. This means that users who wish to continue using Whonix ™ TemplateVMs on Qubes must always upgrade to the latest stable Whonix ™ TemplateVM versions within one month of their release.
We aim to announce both types of events one month in advance in order to remind users to upgrade.

Learning more about Whonix ™ is the best way to determine whether it is a suitable solution in your personal circumstances. The following chapters are recommended:
- The Warning page to understand the security limitations of Whonix ™ and Tor.
- Further information about Whonix ™ Features.
- The implied Trust placed in Whonix ™ when it is used.
- The Security Guide, Advanced Security Guide and Design chapters detailing the Whonix ™ specifications, threat model and implementation.
- Other relevant Documentation explaining how to use Whonix ™ safely.
- https://www.torproject.org/about/overview.html.en [archive]
- https://en.wikipedia.org/wiki/Debian [archive]
- In Qubes-Whonix ™, these VMs are named
- Current practical, low-latency, anonymity designs like Tor fail when the attacker can see both ends of the communication channel (traffic going into and out of the Tor network). If both flows are visible [archive], simple statistics can determine whether they match up.
- For example, for the next release use the tag "Whonix ™ 15" and status "Open".
- This also relieves Whonix ™ developers from needing to diagnose and support old-stable versions of Qubes/Debian/Whonix ™, which duplicates the maintenance burden.
