Release notes for libguestfs 1.6.0
----------------------------------

These release notes only cover the differences from the previous
stable/dev branch split (1.4.0).  For detailed changelogs, please see
the git repository, or the ChangeLog file distributed in the tarball.

New features

 - Use a new method for creating and caching the appliance.  This
   greatly improves the performance of libguestfs, often by a factor
   of x 4 to x 5.

 - Support for guest inspection (like virt-inspector) via the ordinary
   API and all language bindings.  'guestfish -i' option is as a side-
   effect much quicker.

 - virt-inspector and core inspection API can now detect guests running:
   Fedora, Debian, Ubuntu, Windows, Red Hat Enterprise Linux, CentOS,
   Scientific Linux, Gentoo, Pardus, Arch Linux, MeeGo.

 - Support for LUKS whole-disk encryption in guests.

 - PHP bindings.

 - Progress messages (and progress bars in guestfish and virt-resize)
   for certain long-running operations.

 - virt-df is now much more efficient.  Use '--one-per-guest' to restore
   the old per-guest isolation behaviour.

 - guestfish 'copy-in' and 'copy-out' commands for copying files and
   directories recursively in and out of the guest.

 - guestfish 'hexedit' command for doing binary edits to devices and
   files.

 - Change guestfish -i syntax to allow commands to be specified on the
   command line (retaining backwards compatibility).

 - guestfish '-d <domain>' for adding disks from libvirt domains.

 - 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.

 - virt-edit '-b' option to create a backup of edited files.

 - virt-edit '-e' option for non-interactive edits to files.

 - Ability to capture core dumps from the appliance (thanks Matthew Booth).

 - virt-rescue now shuts down cleanly (thanks Matthew Booth).

 - virt-rescue now has a --network option to enable network access.

 - virt-resize can now handle guests which use GPT partition table format.

 - virt-resize has better support for shrinking guests.

 - virt-resize supports qcow2-format guests.

 - $TMPDIR can be used to override almost all temporary directory usage.

 - OCaml users can use an alternate OO-style of coding, eg. g#launch ()

 - The API supports calls which take optional parameters, eg.
     $g->add_drive_opts ("disk", readonly => 1);

 - Trace output now escapes and shortens large strings (thanks
   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

 - CVE-2010-3851 libguestfs: missing disk format specifier when adding a disk
   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.

New APIs

  download-offset, file-architecture, findfs-label, findfs-uuid,
  inspect-os, inspect-get-arch, inspect-get-distro,
  inspect-get-filesystems, inspect-get-major-version,
  inspect-get-minor-version, inspect-get-mountpoints,
  inspect-get-product-name, inspect-get-type, is-blockdev, is-chardev,
  is-fifo, is-lv, is-socket, is-symlink, list-filesystems, luks-add-key,
  luks-close, luks-format, luks-format-cipher, luks-kill-slot,
  luks-open, luks-open-ro, lvm-clear-filter, lvm-canonical-lv-name,
  lvm-set-filter, part-to-dev, pread-device, pwrite-device,
  upload-offset

Internals

 - Use size_t for loop iterators.
 - Refactor the library code into separate files.
 - Refactor the generator code into separate files.
 - Generate guestfish commands.
 - guestfish & guestmount options processing is unified.
 - Protocol changes:
     error message size increased to 64K
     send errno to library
 - Add 'make bindist' to make a binary distribution.
 - Cleaner behaviour under valgrind.
 - More testing of the guestfish command line options and libvirt
   integration.

stable/dev branch split (1.2.0).  For detailed changelogs, please see
