+------
+
+[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.
