.Vb 3
\& \- 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.  \*(Aqguestfish \-i\*(Aq 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 バインディング。
\&
\& \- Progress messages (and progress bars in guestfish and virt\-resize)
\&   for certain long\-running operations.
\&
\& \- virt\-df is now much more efficient.  Use \*(Aq\-\-one\-per\-guest\*(Aq to restore
\&   the old per\-guest isolation behaviour.
\&
\& \- guestfish \*(Aqcopy\-in\*(Aq and \*(Aqcopy\-out\*(Aq commands for copying files and
\&   directories recursively in and out of the guest.
\&
\& \- guestfish \*(Aqhexedit\*(Aq 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 \*(Aq\-d <domain>\*(Aq for adding disks from libvirt domains.
\&
\& \- guestfish \*(Aq\-N\*(Aq 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 \*(Aqmore\*(Aq and \*(Aqedit\*(Aq commands now work with arbitrary files.
\&
\& \- guestfish \*(Aq\-\-echo\-keys\*(Aq 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 \*(Aq\-b\*(Aq option to create a backup of edited files.
\&
\& \- virt\-edit \*(Aq\-e\*(Aq 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.

\& \- 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.

\& \- 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 \*(Aqmake bindist\*(Aq to make a binary distribution.
\& \- Cleaner behaviour under valgrind.
\& \- More testing of the guestfish command line options and libvirt
\&   integration.
