Release notes for libguestfs 1.14.0
-----------------------------------

UPDATED TO COMMIT b0605f265be3f501930516ff95deab2910ced3ac

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-sparsify: A new tool to make virtual machine disk images sparse.

  inspection:

   - Improve detection of Windows disks.

   - Add support for ttylinux (a minimal Linux).

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

  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.

  febootstrap:

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

  virt-resize:

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

  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.

  misc:

Security

New APIs

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

  compress-out, compress-device-out, set-smp, get-smp

Internals

 - 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.

Bugs fixed

            ./bugs-in-changelog.sh 1.12.0..

     robust to use from other programs.

   - virt-ls -lR option allows complex file iteration and guest analysis.

   - virt-win-reg supports HKEY_USERS\<SID> and HKEY_USERS\<username>.

   - virt-win-reg new option --unsafe-printable-strings allows printable

stable/dev branch split (1.8.0).  For detailed changelogs, please see
the git repository, or the ChangeLog file distributed in the tarball.

New features

 - libguestfs and tools can be used against live virtual machines.
   See the 'guestfish --live' and 'guestmount --live' options, and (for
   the low-level interface) the new APIs set-attach-method and
   get-attach-method.

 - New virt tools:
   virt-copy-in, virt-copy-out, virt-tar-in, virt-tar-out.

   each event, makes it possible to call the API from other languages,
   and allows nearly all log, debug and trace messages to be rerouted
   from stderr.

   for large cached files that should survive reboot (instead of /tmp).

 - guestfish, guestmount -m option allows mount options to be passed
   through to the underlying filesystem.

   messages (a guestfish progress bar) if it takes longer than 5
   seconds to run.

 - Several long-running commands where we are unable to estimate time
   to completion generate "pulse mode" progress events.  Progress bar
   in guestfish has been updated to display these.

 - Publish new example code in: C, Perl, Python, OCaml, Ruby.

 - New virt-dhcp-address example program.

Security

  [none]

New APIs

  first-private, get-attach-method, inspect-get-drive-mappings,
  inspect-get-product-variant,
  inspect-get-windows-current-control-set, next-private, resize2fs-M,
  set-attach-method.

Internals

 - The 'HACKING' file is obsolete.  The contents have been moved into
   a section of the guestfs(3) manual page.

 - libguestfs-test-tool simplified.  It no longer needs the static
   binary or tries to construct an ISO.

 - guestfish '-N' option supports several new prepared disk image types:
         lvfs : disk with LV formatted with filesystem
           lv : disk with LV
     bootroot : boot+root
   bootrootlv : boot and root on LV

 - guestfish 'more' and 'edit' commands now work with arbitrary files.

 - guestfish '--echo-keys' option allows you to echo keys/passphrases
   while typing them.

 - guestmount now supports -a / -d / -i options, like guestfish.

 - Use virtio-serial for communications with the appliance.  This
   also has a major performance benefit.

   Matthew Booth).

 - Autosync is now on by default, resulting in more reliable behaviour
   when the handle is closed.

 - virt-df --uuid option allows you to follow a domain across migration
   and renaming.

 - Translations of manual pages.

Security

   https://www.redhat.com/archives/libguestfs/2010-October/msg00036.html
   This is comprehensively fixed in this release, and the fix will be
   backported to the other stable branches after more testing.

 - virt-inspector no longer relies on untrusted guest code to list
   applications in some guests.

  download-offset, file-architecture, findfs-label, findfs-uuid,
  inspect-os, inspect-get-arch, inspect-get-distro,
  inspect-get-filesystems, inspect-get-major-version,
