RELEASE NOTES FOR LIBGUESTFS 1.4

       These release notes only cover the differences from the previous stable/dev branch split
       (1.2.0).  For detailed changelogs, please see the git repository, or the ChangeLog file
       distributed in the tarball.

   New features
        - guestfish lets you choose a prepared disk image, eg:
            guestfish -N fs:ext4

        - Add write support to guestmount (FUSE) module.

        - virt-resize can now resize the content of partitions and logical
          volumes in the guest, and we have better support for shrinking guests.

        - Bash tab-completion script for guestfish.

        - Add ZFS support to virt-rescue.

        - New tool 'virt-make-fs' for creating filesystems with content.

        - Allow suffixes on any guestfish number parameter, eg. "1M".

        - guestfish 'man' command opens the manual page.

        - guestfish supports a "heredoc" syntax for uploading files:
            upload -<<_end_ /foo
            content
            _end_

        - Some guestfish commands now print their output in octal or hex
          where appropriate (RHBZ#583242).

        - Allow dash prefix on guestfish command line.  This ignores any
          error from the second command:                   (RHBZ#578407)
            guestfish -- cmd1 : -cmd2 : cmd3

        - guestfish -h / help command now returns an error for non-existent
          commands (RHBZ#597145).

        - New 'supported' command in guestfish to list optional groups of
          commands which are supported by the daemon / configuration.

        - virt-inspector and guestfish -i now work for filenames which
          contain spaces (RHBZ#507810).

        - Change the protocol to use link-local addresses, to avoid
          conflicting with any address that the host might be using
          (RHBZ#588763).

        - libguestfs now sets the correct time and timezone on filesystem
          modifications.

        - Sort the domains into alphabetical order in virt-df.

        - Make mkfs-b command work for FAT and NTFS by mapping the blocksize
          parameter to the cluster size (RHBZ#599464).

        - Add version numbers to Perl modules (RHBZ#521674).

        - Localization now works for all the libguestfs tools (RHBZ#559963).

        - Tools now support filesystem-on-image VMs (RHBZ#590167).

        - virt-list-partitions has a '-t' option to show the total size of disks.

        - Include extra Augeas lenses in the supermin appliance (Matthew Booth).

        - Add error and close callbacks.

        - Add explicit close method in the Perl API.

        - Multiple fixes for RHEL 5 compatibility.

        - Multiple fixes for Debian/Ubuntu compatibility.

        - Multiple revisions to improve the documentation.

   Security
        - Fix a potential DoS in virt-inspector and virt-v2v if a specially
          crafted disk image contained a char device in place of one of the
          configuration files that we read under /etc (RHBZ#582484).

        - Extend the protocol to support sending arbitrary 8 bit data buffers.
        - Ship 'BUGS' file with releases.  This is a summary of the bugs in
          the Red Hat Bugzilla database.
        - Ship 'RELEASE-NOTES' file with releases, containing release notes.
        - Unify supermin appliance building into one place, in febootstrap 2.7.
