Release notes for libguestfs 1.6.0
----------------------------------
-[updated to commit d75a2bff1264828f02b68a9c8bc7eb2521bd6684]
These release notes only cover the differences from the previous
stable/dev branch split (1.4.0). For detailed changelogs, please see
New features
- Use a new method for creating and caching the appliance. This
- greatly improves the performance of libguestfs.
+ 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.
- - Support for LUKS-encrypted guests.
+ - 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.
- guestfish 'hexedit' command for doing binary edits to devices and
files.
- - Change guestfish -i syntax slightly to allow commands to be specified.
+ - 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 '--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-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.

Internals
- 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.
+ - The Perl inspection code is no longer used by any of the tools.
