[ Colin Watson ]
* New Bazaar snapshot.  Too many changes to list in full, but some of the
  more user-visible ones are as follows:
  - GRUB script:
    + Function parameters, "break", "continue", "shift", "setparams",
      "return", and "!".
    + "export" command supports multiple variable names.
    + Multi-line quoted strings support.
    + Wildcard expansion.
  - sendkey support.
  - USB hotunplugging and USB serial support.
  - Rename CD-ROM to cd on BIOS.
  - Add new --boot-directory option to grub-install, grub-reboot, and
    grub-set-default; the old --root-directory option is still accepted
    but was often confusing.
  - Basic btrfs detection/UUID support (but no file reading yet).
  - bash-completion for utilities.
  - If a device is listed in device.map, always assume that it is
    BIOS-visible rather than using extra layers such as LVM or RAID.
  - Add grub-mknetdir script (closes: #550658).
  - Remove deprecated "root" command.
  - Handle RAID devices containing virtio components.
  - GRUB Legacy configuration file support (via grub-menulst2cfg).
  - Keyboard layout support (via grub-mklayout and grub-kbdcomp).
  - Check generated grub.cfg for syntax errors before saving.
  - Pause execution for at most ten seconds if any errors are displayed,
    so that the user has a chance to see them.
  - Support submenus.
  - Write embedding zone using Reed-Solomon, so that it's robust against
    being partially overwritten (closes: #550702, #591416, #593347).
  - GRUB_DISABLE_LINUX_RECOVERY and GRUB_DISABLE_NETBSD_RECOVERY merged
    into a single GRUB_DISABLE_RECOVERY variable.
  - Fix loader memory allocation failure (closes: #551627).
  - Don't call savedefault on recovery entries (closes: #589325).
  - Support triple-indirect blocks on ext2 (closes: #543924).
  - Recognise DDF1 fake RAID (closes: #603354).

[ Robert Millan ]
* Use dpkg architecture wildcards.

[ Updated translations ]
* Slovenian (Vanja Cvelbar).  Closes: #604003
* Dzongkha (dawa pemo via Tenzin Dendup).  Closes: #604102
