+-----------------------------------
+
+These release notes only cover the differences from the previous
+stable/dev branch split (1.10.0). For detailed changelogs, please see
+the git repository, or the ChangeLog file distributed in the tarball.
+
+New features
+

+ API or by hitting ^C in guestfish.
+
+ - New guestfish "display" command for displaying graphical files
+ inside guests.
+
+ - In guestfish, tab completion now works on /dev/mapper devices.
+
+ virt-inspector:
+

+ the low-level interface) the new APIs set-attach-method and
+ get-attach-method.

+ 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.
+

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

+ more quickly.
+
+ - Excluded packages in the appliance are now listed in a separate
+ file appliance/excludelist.in, and can be customized per-distro.
+
+Bugs fixed
+
+ - 663407 readlink and readlinklist returns /sysroot/ in some paths
+ - 661280 virt-rescue: panic when shutting down: "/sbin/reboot: No such file or directory"
+ - 657499 checksum: wrong check sum type causes umount to fail

+ 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.

+ 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.

+ 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 supports qcow2-format guests.
+
+ - $TMPDIR can be used to override almost all temporary directory usage.

+
+ - 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,
