changelog

tails (4.0~beta1) unstable; urgency=medium

  * Major changes
    - Upgrade to a snapshot of Debian 10 (Buster) from 2018-08-06.

  * Removed features
    - Remove Traverso (Closes: #16353).
    - Remove Scribus (Closes: #16290).
    - Remove LibreOffice Math (Closes: #16911).

  * Bugfixes
    - Fix Electrum wrapper's persistence check (Closes: #16821).
    - Remove pre-generated Pidgin accounts (Closes: #16744).
    - Hide the security level button in the unsafe browser (Closes:
      #16735).
    - Only hide unlocked TailsData partitions from the boot device
      (Closes: #16789).

  * Minor improvements and updates
    - Remove KeePassX and replace it with KeePassXC (Closes:
      #15297). As KeePassX was used around for a longer time, we don't
      need automatic upgrading cappability from old KeePass file
      format (Tails 2 times). The user can still import those old
      files, if they want to access it.
    - Ship a pre-compiled AppArmor policy to make boot faster (Closes:
      #16138).
    - Change the splash screen for Tails 4.0 (#16837). Add SVG source
      while we're at it!
    - Remove our predefined bookmarks and ship default upstream Tor
      Browser bookmarks instead (Closes: #15895).
    - Install bolt for improved Thunderbolt support (Closes: #5463).
    - Don't display the Home launcher on the desktop (Closes: #16799).
      Since the switch to the desktop-icons GNOME Shell extension, the
      nicer XDG-blah name ("Home" in English, translated in many
      languages) is not used to label this launcher anymore: instead,
      the name of the directory is displayed, in this case: "amnesia",
      which makes no sense to our users. Our other options to fix that
      are more costly and we've decided a while ago, when I proposed
      to remove the desktop icons, to keep them until they were too
      expensive to support. So this one goes: we have the Places menu
      already.
    - Add Files to favorite apps (Closes: #16799). This gives another
      entry point to the home folder, which partially mitigates any UX
      regression that might be caused by the previous changelog entry.
    - Explicitly install imagemagick. We ship it on purpose (see
      [[contribute/meetings/201707]]).
    - MAT:
      * Drop obsolete optional MAT dependencies it isn't using any
        more.
      * Stop explicitly installing MAT dependencies. The package
        depends on those so we don't need to pull them ourselves.
    - Move translations from root-terminal.desktop.in into own PO
      files (Closes: #15335).
    - Drop obsolete live-boot patch: the bug it workarounds only
      happens with CONFIG_AUFS_DEBUG enabled. We disable
      CONFIG_AUFS_DEBUG in config/chroot_local-hooks/13-aufs and the
      Debian package did it as well (Refs: Debian#886329).
    - Rename /usr/share/amnesia to /usr/share/tails.
    - Drop APT pinning for non-existing live.debian.net, that we
      haven't used since 2010.
    - Don't install the cryptsetup initramfs integration and startup
      scripts (Closes: #16264). We probably only need the binaries.
      Not installing the initramfs integration will get rid of some
      noise.
    - Don't install full-blown cryptsetup, take 2 (Refs: #15690,
      #16264).
    - Disable live-tools.service (Closes: #16324). This service is only
      useful to display the "Please remove the live-medium, close the
      tray (if any) and press ENTER to continue:" prompt on shutdown,
      that we don't want to display in Tails: shutdown and memory
      erasure should not require a confirmation once the user has
      triggered it. In Stretch this code was broken and we were
      relying on this. But the Buster upgrade of this code has
      repaired it, so I sometimes see that prompt. This might also
      explain some issues such as #16312.
    - AppArmor: allow cups-brf, driverless, and gutenprint53+usb
      printer backends (Closes: #15030). Technically, cups-brf and
      driverless are not third-party and should be confined more
      strictly with "ixr", under the cupsd profile. But I don't know
      how to to test these backends and confining them more strictly
      may break them.  Anyway, that's an upstream matter: the purpose
      of our Tails-specific patch is to replace the third party
      backends /usr/lib/cups/backend/* catch all rule, that doesn't
      work for us, and not to keep the list of backends which come
      with CUPS up-to-date.
    - Make export_gnome_env() exit early if gnome-shell isn't running.
      Without this e.g. the automated test suite, which will call
      export_gnome_env() before gnome-shell is running, will have its
      journal polluted with errors about this. This is not the first
      time I see this and get worried and waste minutes investigating,
      so let's just fix it.

  * Build system
    - Bump VM_MEMORY_BASE to 2048M. With the previous 1024M setting,
      the squashfs preparation gets OOM-killed.
    - Limit the memory used by mksquashfs to 512M (Closes: #16177). By
      default mksquashfs will use 25% of the physical memory. So when
      we use the "ram" build option, build in a VM with 13GB of RAM,
      of which up to 12G is supposed to be used by the build tmpfs,
      mksquashfs will try using 13/4 = 3.25G of memory. And then it
      will get reaped by the OOM killer more or less occasionally
      depending on how much space is really used in the build tmpfs
      and how much memory the rest of the system is using. So let's
      limit the memory used by mksquashfs to 50% of the memory we
      allocate to the build VM, excluding the part of it that we
      expect tmpfs data to fill. In passing, the fact mksquashfs does
      not get killed every time suggests that our current
      BUILD_SPACE_REQUIREMENT value exceeds the real needs of a build:
      a value around 10 or 11G should be enough. But that will be for
      another commit.
    - Use xz with default settings to compress non-release SquashFS
      (refs: #16177). squashfs-tools 1:4.3-11, used to build
      feature/buster, does not consistently honor the value passed to
      -mem: the xz compressor does but at least the gzip and lzo ones
      don't. This makes the build often fail because mksquashfs gets
      reaped by the OOM-killer. Our only other option is currently to
      bump the build VM memory a lot, which is going to be painful on
      developers' systems and might not be an option on Jenkins. So
      let's fall back to xz with default settings (not the crazy slow
      but efficient we use at release time) when building non-release
      images.
    - Rename the "gzipcomp" build option to "fastcomp". What matters
      in the "user" interface is not the exact algorithm that's used,
      it's the fact it's supposed to be faster than the compression
      settings we use to build releases. We may have to changes these
      fast(er) settings occasionally, possibly to use a non-gzip
      algorithm. So let's keep supporting "gzipcomp" for backward
      compatibility but stop documenting it. Instead, support and
      document "fastcomp".
    - Add the vmproxy+extproxy build option. When enabled, use the
      vmproxy but configure it to in turn use the exproxy set via the
      http_proxy environment variable.
    - Support the case when we don't ship a custom AppArmor feature
      set. Let's keep this sanity check for the times when we do ship
      a custom feature set, but building an ISO without a custom one
      should remain supported. (Closes: #15149)
    - Don't remove packages whose deinstallation removes most of the
      system; don't explicitly remove packages that are taken care of
      by "apt-get autoremove" already. On Buster, removing dpkg-dev
      or make deinstalls python3, gnome-shell and more.
    - Install all "Priority: standard" packages via an explicit
      packages list instead of via --tasks (Closes: #15690). This will
      make it easier to remove some of these packages from the list of
      those that should be installed in the first place, as opposed to
      letting them be installed by tasksel only to uninstall them
      later. I've seeded tails-000-standard.list with the output of:
      tasksel --task-packages standard | sort … run on a clean Buster
      system. Also:
       * live-build forcibly translates --packages-lists="standard"
         into "tasksel install standard", so to make this change
         effective we also need to switch to "--packages-lists
         minimal" or "--packages-lists none". The former has
         problematic side-effects so let's use the latter.
       * Add to tails-common.list some of the packages that were
         previously installed automatically, e.g. via live-build's
         lists/standard → lists/minimal.

  * Test suite
    - Tons of tiny updates for the Stretch → Buster transition, mainly
      updated reference images, but also a few other trivial changes
      (e.g. close with Alt+F4 instead of menu, or vice versa) due to
      changes in applications.
    - Drop test case about migrating from a Jessie-area persistent
      volume. If our code happens to support Tails 2.x → 4.x upgrades
      without going through 3.x, fine. But let's not spend cycles in
      our CI to guarantee this.
    - Revert "Test suite: add backward compatibility with redir <
      3.0." We don't support running the test suite on Jessie anymore.
    - Adjust dhclient listening address for Buster.
    - Bump timeout for poweroff from 3 to 10 minutes (Refs: #16312).
    - Adjust dogtail patterns for gobby test (Closes: #16335). With the
      gobby upgrade from 0.5.0 to 0.6.0 pre-series, the case changed a
      little for a menu item and the window it leads to.
    - Update key shortcut to close seahorse's Preferences window
      (Closes: #16341). The “Close” button is gone from the
      Preferences window in the buster version of the seahorse
      package, making it impossible to close that window. Switch to
      sending ESC instead of Alt-C.
    - Update MAT test case for MAT2 (Closes: #16623).
    - Add debug logging for when we call Sikuli. When following a
      (debug) log live (through `--format debug`) I find this change
      useful to know what is going on *right now* since Sikuli only
      reports what it has done after it is done.
    - Be more careful when finding ASP notifications. For some reason
      both the label and button has a "weird" invisible (despite
      `showingOnly`) twin located just below the Applications
      menu. So let's make some extra effort to actually find the real
      notification, and then look for the label and button among its
      children.
    - Remove obsolete method. Display::take_screenshot() hasn't
      existed for years.
    - Remove workaround "Desktop icons are sometimes not shown" (Refs:
      #13461)
    - Wait longer between search steps in the GNOME Overview. On
      jenkins.lizard — which was under high load at that time — I've
      seen failures while starting GNOME Terminal from the Overview,
      where:
       - The debug log claims we did type "c", waited 1 second, then
         typed "ommandline", then slept another 1 second, then pressed
         Enter. I.e. just as the code says.
       - The video shows that GNOME Shell did pick up "c", which
         selected the first search result ("Configure Persistent
         Volume"), but then there's no trace of typing "ommandline".
         So I suspect that "ommandline" was lost because GNOME Shell
         was still busy, somehow. Let's sleep a bit longer before
         these steps, to give GNOME Shell a better chance to recover
         and notice keyboard input.
    - Log exceptions thrown in generated (i.e. snapshot) steps (Refs:
      #16747). Hopefully this will help us track down these elusive
      exceptions.
    - Extend waiting time for additional software to be installed.
    - Sometimes we need more more time to load a page over tor.
    - Remove useless TailsUpgraderApplyingUpgrade.png. The "progress
      prompt" it was used for just flashes by and can easily be
      missed. There is no reason at all to wait for it since the only
      two final outcomes are success or failure, which we already look
      for.
    - debug_log() when we save/restore snapshots. These actions can
      take a long time (especially saving snapshots on a system under
      load) and can make it appear like if the test suite has gotten
      stuck for those following the debug log.
    - Don't rely on mtimes from Debian packages we download, to
      indicate which one has the biggest version (Closes: #16819).
      These mtimes are copied from the HTTP server where APT downloads
      packages from, which contradicts our assumption that the newest
      file must be the one with the biggest version. Instead we use ls
      to sort by version number, to pick the biggest version.
    - Only send TAB every second to get the syslinux kernel
      command-line (Closes: #16820). Our syslinux has a timeout of 5s so
      sending TAB every second should be enough to guarantee we do
      open the kernel command line. As anonym reported, "the spammer
      makes the splash show for significantly longer: I've seen >10x,
      so the boot splash never managed to appear, which is worrying".
    - Drop workaround to make the TAB spammer compatible with the UEFI
      firmware (Closes: #16820). As reported by anonym on #16820, and
      confirmed by my testing, pressing TAB doesn't seem to open the
      UEFI configuration, so the very reason why we had this
      workaround is gone.

  * Adjustments for Debian 10 (Buster) with no or very little user-visible impact
    - Adjust APT sources and pinning for Buster.
    - Refresh and unfuzzy patches for Buster.
    - Pass --ellipsize to zenity (refs: #16286). This fixes dialog
      width and height on Buster.
    - Update expected /etc/passwd and /etc/group for Buster.
    - Display TopIcons systray on the left of the system menu (Refs:
      #14796).
    - Remove apparmor-adjust-freedesktop-abstraction.diff patch,
      merged upstream in apparmor. The
      9d8b6f4dbd8a04470490ae2bfd52044906abd7f6 commit (first appeared
      upstream in apparmor v2.13.1) implements this change in a
      generic way.
    - Adjust hook to the fact the Dovecot AppArmor profiles are not
      shipped in /etc anymore.
    - Import iuk.git's feature/buster branch at commit 919335e
      (Closes: #16286).
    - Enable desktop-icons gnome-shell extension (Closes: #16283).
    - Add autostart script to have gnome-shell trust desktop icons
      (Closes: #16283). Various conditions must be met for gnome-shell
      to make desktop icons launchable, including file
      permissions. But the GIO metadata::trusted setting is also
      needed, and can apparently only be set from an opened session,
      so let's set the right things with an autostart script.
    - Drop code that sets the cursor to "WATCH" (hourglass) after
      logging in (Closes: #16305) This fixes "GDM's GNOME Shell floods
      the Journal with XFIXES/cursor issues on Buster" by importing
      the relevant bits of greeter:feature/buster's commit abad17b6.
    - Remove 8 development packages that are not part of Tails 3.11 so
      we probably don't need to ship them in Tails 4.0 either (Closes:
      #16272).
    - Completely get rid of Qt4 (Closes: #15182).
    - SSH client: remove obsolete CompressionLevel setting (Closes:
      #16320).
    - Removing /usr/share/live/config/xserver-xorg/intel.ids (Closes:
      #14991). Let's hope the graphics hardware issues we fixed via
      that file is fixed no.
    - Adjust Onion Grater and AppArmor configuration for OnionShare
      1.3 (Closes: #16306).
    - Have OnionShare 1.3 connect to the system Tor via Onion Grater
      for the control port (Closes: #16306). By default, OnionShare
      1.3 will start its own tor process, which can't possibly work on
      Tails.
    - Don't install binutils-* (Closes: #16272). It wasn't in Tails 3.x
      and we have no reason to ship it in 4.0.
    - Install mat2 instead of the transitional mat package.
    - Don't suspend automatically (Closes: #16624)
    - tails-additional-software: Adjust arguments to
      tails-persistence-setup (Closes: #16622). It seems like the perl
      library which previously nicely handled the tps command-line
      arguments now doesn't support taking dashes instead of
      underscores anymore.
    - Start tails-unblock-network in a blocking way (Closes: #16620)
      This reverts commit 59e99c51f15ab9e756e287acb03b4d3a91ca1dd2 in
      greeter.git. NetworkManager starting at the same time as GNOME
      Shell makes things racy: the Wi-Fi password prompt is sometimes
      not displayed (unreproduce on Debian Buster Live).
    - Patch ibus to fix an issue that prevented the on-screen keyboard
      from displaying in Tails Greeter (Closes: #16291).
    - oniongrater: give onioncircuits empty STATUS_SERVER events.
      Connection to STATUS_SERVER events is required by stem 1.7
      connect() function, but we actually don't need them, so let's
      suppress them (Closes: #16626).
    - Fix GNOME bookmarks file for Buster (Closes: #16629).
    - Build VeraCrypt packages with our patches applied for Buster
      (Closes: #16634).
    - Avoid new "render" group stealing a GID we have already
      statically allocated to another group (Closes: #16649) With the
      systemd 241-1~bpo9+1 → 241-3~bpo9+1 upgrade, udev.postinst now
      creates a "render" system group, which shifts GIDs and makes our
      devel branch FTBFS.
    - update-acng-config: add support for 4.x and 5.x, drop 2.x. We
      won't build 2.x releases anymore but we'll start building 4.x
      from this branch soon.
    - Restore Plymouth theme to "text" (Closes: #16743). The default
      theme in Buster ("futureprototype") is Debian-branded and thus
      unsuitable for Tails. Let's revert to the one we use in Tails
      3.x.
    - Stop installing caribou and libcaribou*: they're not used by
      GNOME Shell in Buster anymore (Closes: #16628)
    - Allow read access to /etc/machine-id in the AppArmor profile for
      Thunderbird (Closes: #16756). It breaks access to the D-Bus
      service where the GNOME on-screen keyboard listens on Buster.
    - Fix screen locker not working in Buster (Closes: #16763).
    - Hide lstopo in the Applications menu (Closes: #16797). It's
      pulled as a dependency by aircrack-ng but is probably not useful
      to the vast majority of Tails users.
    - Hide nm-connection-editor in the Applications menu (Closes:
      #16798). We still need the network-manager-gnome package that
      installs this .desktop file (for details, see
      commit:40290be3651eaa6f08346231aef80eddd8b33c64), but there's no
      reason to expose it directly to users.
    - TorStatus: call our custom destructor to avoid a use-after-free
      crashing GNOME Shell (Closes: #16791). It was ported to an ES6
      class in the process.
    - Copy dmidecode to initramfs (Closes: #16857). On Buster,
      partprobe complains if dmidecode is missing. It's not clear what
      the consequences are, at least it doesn't cause partprobe to
      exit with an error status code - but it's cheap to just copy
      dmidecode to the initramfs.
    - Adjust path for webext-ublock-origin 1.19.0+dfsg-2 (Closes:
      #16858).
    - Update Tor Browser AppArmor profile to take into account new
      uBlock installation path (Closes: #16858).
    - Disable the uBlock logger sidebar. This  brings back
      the hack we had before we removed it in #16206. Without this,
      the uBlock logger sidebar is displayed.
    - Reintroduce the same APT pinning as we use in 3.x for uBlock.
      Granted, the version from Buster should probably be sufficient
      right now, but it probably won't be once Tor Browser gets
      updated to a future major Firefox ESR. And in the meantime,
      this pinning discrepancy between devel and feature/buster makes
      it harder to maintain our patch against
      /usr/share/webext/ublock-origin/js/background.js.
    - Drop obsolete libdesktop-notify-perl patches: they were merged
      upstream.
    - Use X.Org in amnesia's GNOME session (Closes: #12213). Since a
      few months gdm3 defaults to Wayland in Debian testing/sid, just
      like upstream. But we're not ready yet.
    - Adjust Greeter's gdm-tails.session for Buster (Closes:
      #12551). This should ultimately be applied in greeter.git, but
      let's deal with it as a patch for now to avoid having to
      maintain two parallel branches of the Greeter.
    - Patch udisks2 and libblockdev and fix Tails Installer to repair
      USB boot on Buster (Closes: #14809).
    - Install gnome-user-docs directly instead of the gnome-user-guide
      transitional package.
    - Install the "crypto" libblockdev plugin (Closes: #14816). It's
      needed by recent udisks to do crypto operations.
    - Use ConditionUser=1000 instead of manually testing the output of
      `id -u' in some of our systemd services.
    - Have debootstrap install gnupg when setting up the chroot.
      Otherwise the build fails after debootstrap has done its job and
      live-build tries to use apt-key.
    - Don't try to install the obsolete gnome-search-tool package.
      It's been removed from testing/sid by its maintainers:
      https://bugs.debian.org/885975
    - Don't try to retrieve syslinux.exe from the syslinux source
      package. Since syslinux 3:6.03+dfsg1-1 this file is (rightfully)
      not included anymore in the Debian source package.  This commit
      is meant to fix the feature/buster ISO build. We of course need
      to find a proper solution, which is what #15178 is about.
    - Drop our pinned AppArmor feature set (Closes: #15149). On current
      Buster the AppArmor package pins to the Linux 4.14.13-1 feature
      set and I expect it'll keep pinning something that should work
      with the policy shipped in Buster.
    - Drop Stretch-specific workaround. This essentially workarounds
      4f8b50afb10a1ce1faf7645971bc020d2eb5d7dd,
      3e2d8a6a025b86f8191d125783ad507c57171bad and
      d56633a3089e5b177e07c2888442745557772f42.
    - Disable the usr.bin.man AppArmor profile. On Buster it breaks
      apparmor.service due to "profile has merged rule with
      conflicting x modifiers" that's most likely caused by the "/**
      mrixwlk" rule vs. our tweaks for aufs support.
    - Import files (from gksu 2.0.2-9+b1) needed for the Root Terminal
      into Git instead of fetching the package and extracting them at
      build time.
    - Use orca's current package name instead of pre-Buster
      transitional one.
    - Stop explicitly installing gstreamer1.0-pulseaudio. This was
      needed on Jessie due to Debian#852870 which was fixed in

tails (3.17) UNRELEASED; urgency=medium

  * Dummy entry for next release.

 -- intrigeri <intrigeri@debian.org>  Sat, 23 Mar 2019 11:32:48 +0000

tails (3.15) unstable; urgency=medium

  * Major changes
    - Upgrade Tor Browser to 8.5.4 (Closes: #16691).
    - Upgrade Thunderbird to 60.7.2 (Closes: #16834).

  * Security fixes
    - Upgrade Expat to 2.2.0-2+deb9u2 (DSA-4472-1).
    - Upgrade OpenSSL 1.0 to 1.0.2s-1~deb9u1 (DSA-4475-1).
    - Upgrade OpenSSL to 1.1.0k-1~deb9u1 (DSA-4475-1).
    - Upgrade Vim to 2:8.0.0197-4+deb9u3 (DSA-4467-1).

  * Bugfixes
    - Recompute CHS values for the hybrid MBR after first-boot
      repartitioning (Closes: #16389). Some legacy BIOS systems won't boot
      otherwise.
    - Strip debug symbols from the aufs kernel module smaller (refs: #16818).
      The primary target was getting the initramfs down under 32MB, hoping
      to repair boot of feature/buster on MacBookPro 8,1. In any cases,
      the user experience should be improved due to a faster boot for
      every user, and a shortened “black screen” duration (between the
      bootloader and the Plymouth splash screen).

  * Minor improvements and updates
    - Make “Unlock VeraCrypt Volumes” show an error message if locking
      fails (Closes: #15794).
    - Add support for booting Tails from a read only sdcard (fromiso),
      through Heads, allowing for measured boot on some tamper-evident
      hardware (https://github.com/osresearch/heads/issues/581).

  * Build system
    - Patch Thunderbird packages from Debian when building Tails images
      (Closes: #6156).
    - Improve tooling to maintain and update PO files (Closes: #15403),
      rewriting some tools and moving code to the jenkins-tools submodule.
    - Implement preliminary steps needed to make the ikiwiki PO plugin
      able to update PO files for languages that are disabled on the
      website (refs: #15355).

tails (3.14.2) unstable; urgency=medium

  * Security fixes
    - Upgrade Tor Browser to 8.5.3 (Closes: #16835).

    - tails-screen-locker: Don't use dim-label style class
      (Closes: #16802).

 -- Tails developers <tails@boum.org>  Sun, 23 Jun 2019 11:52:49 +0200

tails (3.14.1) unstable; urgency=medium

  * Security fixes
    - Upgrade Tor Browser to 8.5.2-build1 (Closes: #16824).
    - Upgrade Thunderbird to 60.7.0 (Closes: #16742).
    - Upgraded Linux to 4.19.37-4 (Closes: #16823).

  * Bugfixes
    - Only probe for partitions on the boot device when setting up
      TailsData. Without arguments partprobe will scan all devices,
      and if it encounters a device it doesn't support (e.g. fake
      raid-0 arrays) it will return non-zero, thus aborting Tails'
      partitioning script, resulting in an unbootable install
      (Details: #16389).

  * Minor improvements and updates
    - Upgrade tor to 0.4.0.5-1~d90.stretch+1, the first stable
      candidate in the 0.4.0.x series (Closes: #16687).
    - Completely disable IPv6 except for the loopback interface. We
      attempt to completely block it on the netfilter level but we
      have seen ICMPv6 "leaks" any way (related to Router
      Solicitation, see: #16148) so let's just disable it. We keep
      enabled on the loopback interface since some services depends on
      ::1 being up.
    - create-usb-image-from-iso: Use syslinux from chroot. We used the
      syslinux from the vagrant box before, which caused issues with
      when building Tails/Buster with a Stretch vagrant box and then
      cloning the image via Tails Installer with syslinux from Buster
      (Closes: #16748).
    - Set Tor Browser's homepage to https://tails.boum.org/home/testing/
      if building anything but a stable release. This page explains the
      dangers of using a non-stable release. (Closes: #12003)

  * Build system
    - auto/{build,config}:
      * consistently use fatal() to error out, and prefix its message
        with "E: " to help distinguish them from the noise produced by
        tools we call etc.
      * Similarly, also prefix informational message with "I: ".
      * drop support for GnuPG 1.x.
      * clone more build output to the log file.
      * Drop obsolete check for syslinux version. This version
        requirement is satisfied by Jessie and it is doubtful Tails
        would build in anything older.
      * auto/build: drop a few checks for conditions that are already
        satisfied in the supported build environments.
    - Revert "Build system: try to be smart again by fetching only the
      refs we need." This optimization overrides the trick we have on
      Jenkins (set_origin_base_branch_head in
      https://git.tails.boum.org/jenkins-jobs/tree/macros/builders.yaml),
      that ensures that a reproducibly_build_Tails_ISO_* job builds
      from the commit used by the first build. (Closes: #16730)

  * Test suite
    - Fix mistake with execute() vs spawn() when starting the upgrader.
    - Don't filter during pcap capture, instead let's just apply the
      same filtering when we are inspecting the pcap files. This way
      any pcap file saved on failure will include the full capture,
      and not just the packets sent by the system under testing, which
      sometimes makes it hard to understand what is going on.
    - Also include the content of /var/log/tor/log in $scenario.tor
      when tor failed to bootstrap (refs: #16793)
    - Don't flood the debug logger with tor@default's journal
      contents.
    - Power off system under testing after scenario. Until now we have
      relied on either one of the generated "snapshot restore" steps
      or the "[Given] a computer" step to implicitly stop the old VM
      when we move on to a new scenario. That meant the old VM was
      still running during the new scenarios @Before@ hooks. If the
      new scenario is tagged @check_tor_leaks that means we start its
      sniffer while the old VM is still running, possibly sending
      packets that then affect the new scenario. That would explain
      some myserious "Unexpected connections were made" failures we
      have seen (Closes: #11521).
    - Only accept IP(v6)/ARP during DHCP check.

tails (3.14) unstable; urgency=medium

  * Security fixes
    - Upgrade Linux to 4.19.0-5 from sid (Closes: #16708).
    - Enable all available mitigations for the Microarchitectural Data
      Sampling (MDS) attacks and disable SMT on vulnerable CPUs
      (Closes: #16720).
    - Upgrade Tor Browser to 8.5 (Closes: #16337, #16706).

  * Bugfixes
    - Install Electrum 3.2.3-1 from our custom APT repository (Closes: #16708).
      The version in sid now displays a warning and exits, while 3.2.3-1 is
      still usable, in the rare cases when it manages to connect to the
      network, despite being affected by problematic phishing attacks which
      will only be solved once the package in Debian is updated to a newer
      upstream version.

  * Build system
    - Bump APT snapshot of the 'debian' archive to 2019051601, needed for
      the MDS mitigations.
    - Don't install the firmware-linux and firmware-linux-nonfree
      metapackages, as packages they pulled are already listed explicitly
      and one might run into version-related issues (Closes: #16708).

  * Minor improvements and updates
    - Remove some packages from the Tails image as their use is not
      widespread while consuming space for everyone. They can still be
      installed and upgraded through Additional Software (Closes: #15291).
      This includes: monkeysphere and msva-perl, gobby, hopenpgp-tools,
      keyringer, libgfshare-bin, monkeysign, paperkey, pitivi,
      pdf-redact-tools, pwgen, traverso, and ssss.
    - Fix missing translations in the Greeter (Closes: #13438).
    - Fix missing newline in unlock-veracrypt-volumes (Closes: #16696).
    - Port fillram to Python 3 (Closes: #15845).
    - Enable localization for new locales introduced in Tor Browser 8.5
      (Closes: #16637).
    - Re-introduce TopIcons GNOME Shell extension (Closes: #16709).
    - Improve internationalization of the Unlock VeraCrypt Volumes
      component (Closes: #16602).

  * Test suite
     - Make tails-security-check's SOCKS port test work when there's a live
       security advisory (Closes: #16701).
     - Make terminology more consistent.

 -- Tails developers <tails@boum.org>  Mon, 20 May 2019 18:52:04 +0200

tails (3.13.2) unstable; urgency=medium

  * Major changes
    - Replace all locale-specific fonts and standard X.Org fonts with
      the Noto fonts collection (Closes: #9956).
    - Install localization support packages for all tier-1 supported languages,
      and only those (Closes: #15807). Current tier-1 supported languages are:
      Arabic, German, English, Spanish, Farsi, French, Italian, Portuguese
      (Brazil), Russian, Turkish, Simplified Chinese, Hindi, Indonesian.
    - Disable the TopIcons GNOME Shell extension (Closes: #16608).
      This extension causes crashes (#11188), does not work on Wayland
      (#8309, #12213) so long-term, we need to remove it anyway.
      In order to learn how much our users rely on this extension and
      on OpenPGP Applet, let's disable this extension for one Tails release.
      While TopIcons is disabled (by default):
      · Users can still use OpenPGP Applet via the system tray in the bottom
        left corner of the desktop.
      · Users who do need TopIcons for other reasons can enable it again
        with 1 command line.

  * Security fixes
    - Upgrade Tor Browser to 8.0.9 (Closes: #16694).
    - Upgrade to Debian Stretch 9.9 (Closes: #16670).
    - Upgrade Thunderbird to 60.6.1 (Closes: #16641).

  * Bugfixes
    - Fix Thunderbird account setup wizard (Closes: #16573).
    - Display poweroff and reboot buttons even when locked (Closes: #15640).
    - Disable emergency shutdown during suspend (Closes: #11729).
    - Provide feedback while starting Onion Circuits (Closes: #16350).
    - Associate .key files with Seahorse (Closes: #15213).
      This partially fixes importing OpenPGP keys from GNOME Files.
    - Don't show spurious notification about "TailsData" while setting
      up a persistent volume (Closes: #16632).

  * Minor improvements and updates
    - Add a suspend button to status-menu-helper (Closes: #14556).
    - status-menu-helper: clean up and refactor.
    - Drop CSS hacks for the uBlock log window (Closes: #16206).
    - Polish 04-change-gids-and-uids code style (Closes: #16322).
    - Create persistence.conf backup in a more robust manner (Closes: #16568).
    - Make the WhisperBack .desktop file translatable in Transifex
      (Closes: #6486).

  * Build system
    - Don't fail the build if Tor Browser supports new locales that we don't ship
      a spellchecking dictionary for (#15807).
    - Fix apt-cacher-ng cache shrinking (Closes: #16020).
    - Remove obsolete usr.bin.onioncircuits AppArmor profile (Closes: #12170).
      All Tails current branches now install onioncircuits 0.6-0.0tails1,
      which ships a more current AppArmor profile than the one we
      have in our own Git tree.
    - Install Electrum from sid (Closes: #16642).
    - Avoid new "render" group stealing a GID we have already statically
      allocated to another group (Closes: #16649).

  * Test suite
    - Disable tests about notifications in case of MAC spoofing failure:
      we have a well-known bug here and these tests do nothing but confirm
      it again and again, which brings no value and has a cost (#10774).
    - Clarify what WebM scenarios are fragile (#10442).
    - Avoid zombies by waiting for killed child processes to exit (#14948).

      /home (Closes: #12156).
