Comment:

 > Yes, I had installed the hardened TBB. As for my sandboxed-tor-browser,
 I think the version is 0.0.3, but I can check it only later (give me 12
 hours).

 Per the 0.0.5 release notes:
 {{{
  * (< 0.0.4) Will not correctly transition to the alpha channel.
    Sorry.  The bundle may or may not be rendered non-functional by the
    transition update, I don't have a good way to test the Tor Browser
    auto update infrastructure with updates that haven't been released
    yet.

  * (>= 0.0.4) When `sandboxed-tor-browser` is launched, it will detect
    the `hardened` bundle and force a reinstall.  This will eradicate the
    existing bundle directory obliterating user customization,
    bookmarks, and downloads (unless the download directory is
    overridden).

    A warning dialog box is displayed prior to booting the user back to
    the installation screen.
 }}}

 > Frankly, I had assumed it would update itself, too.

 That's something for future improvement perhaps, if I can figure out a
 good way to do it.

 Closing, since there's nothing I can do about "there is code that assumes
 that channels never go away deployed, that people try to use to update a
 deprecated bundle".
