RELEASE NOTES FOR LIBGUESTFS 1.14

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

   New features
         Erlang bindings.

         virt-alignment-scan is a new tool to check the alignment of
         partitions within virtual machines or disk images.

         virt-sparsify is a new tool to make virtual machine disk images
         sparse.

         virt-sysprep is a new tool to make cloning guests from a template
         simpler.

       guestfish

          - New commands setenv, unsetenv, to set environment variables.

          - The input file and line number is printed in error messages.

          - guestfish progress bars are now a "mini-library" used by other
            tools too.

       guestmount

          - the --live option (for access to live VMs) now works.

       virt-cat

          - virt-cat can now handle Windows paths and drive letters (RHBZ#693359).

       virt-filesystems

          - the MBR partition type byte is displayed in --long output.

       virt-make-fs

          - virt-make-fs now sets the MBR partition type byte correctly,
            improving compatibility with Windows (RHBZ#746295).

       virt-resize

          - virt-resize can now work with guests using extended and logical
            partitions, in particular Ubuntu guests.

          - virt-resize can now align the first partition of Windows guests,
            improving performance.  The new virt-resize --align-first option
            controls this behaviour.

          - The virt-resize --machine-readable flag makes it possible to use
            virt-resize from other programs.

          - Partitions are now aligned to 128 sectors (usually 64K) by
            default.  This improves efficiency on high-end storage.  The new
            virt-resize --alignment option allows the alignment to be
            adjusted.

       virt-win-reg

          - The syntax for deleting registry keys and values is documented
            in the man page (RHBZ#737944).

       library

          - non-printing characters are escaped correctly in debug output.

          - GUESTFS_EVENT_ENTER is a new event type generated whenever a
            libguestfs function is called.

          - the library contains systemtap/DTrace probes.

          - the library can now be compiled without hivex (RHBZ#723474).

       inspection

          - Improve detection of Windows disks.

          - Adds support for:
                ttylinux - a minimal Linux
                Mageia (thanks Michael Scherer)
                OpenSUSE and zypper (thanks Michael Scherer, Vincent Untz)
                Ubuntu logos (thanks Michael Scherer)
                NetBSD and pkgsrc (thanks Michael Scherer)

          - Handle some guest types that use /dev/root in /etc/fstab.

          - Fix handling of guests with > 26 disks (thanks Matthew Booth)

          - Add support for guests with HP Smart Array disks (thanks Matthew Booth)

       febootstrap

          - FEBOOTSTRAP_KERNEL, FEBOOTSTRAP_MODULES environment variables can
            be set in order to choose which kernel to use for the appliance.

       misc

          - ArchLinux support now working with Linux 3.0 (thanks Erik Nolte)

          - libvirt disks marked <readonly/> are now added readonly when
            using the virt-tools '-d' option.

   Security
         (no security problems were found or fixed in this release)

   New APIs
         compress-out, compress-device-out, copy-device-to-device,
         copy-device-to-file, copy-file-to-device, copy-file-to-file,
         get-smp, part-to-partnum, set-smp.

         The mount API no longer implicitly adds -o sync,noatime options.

         add-domain has a new 'readonlydisk' optional parameter to control
         how <readonly/> disks are handled.

   内部
        - Coverity was run on the source and more bugs were identified and
          fixed.

        - PCRE library is now required to build libguestfs.

        - APIC is now the default for the appliance.  You can also enable
          SMP support in the appliance.

        - OCaml bindings now correctly acquire GC lock during callbacks.

        - Out of tree builds should now work correctly (thanks Hilko Bengen).

        - ./configure --with-extra="..." can be used by packagers to set
          the extra version string.

        - zero, zero-device APIs: if the blocks already contain zeroes,
          don't write zeroes, so that we don't unnecessarily make the
          underlying storage non-sparse.

        - is-zero, is-zero-device APIs: optimize these so zero detection is
          faster.
