Oh yeah, the 7.0.9 release broke the Whonix landing page in Tor Browser, because they closed some security hole in the file:/// resource, which obviously affects the local loading of it.
Guess you’d call that an “Unbreak now” item.

Known issues: The fix we deployed is just a workaround stopping the leak. As a result of that navigating file:// URLs in the browser might not work as expected anymore. In particular entering file:// URLs in the URL bar and clicking on resulting links is broken. Opening those in a new tab or new window does not work either. A workaround for those issues is dragging the link into the URL bar or on a tab instead. We track this follow-up regression in bug 24136.
