10 stable/dev branch split (1.2.0). For detailed changelogs, please see
11 the git repository, or the ChangeLog file distributed in the tarball.
12 New features
14 - guestfish lets you choose a prepared disk image, eg:
15 guestfish -N fs:ext4
16 - Add write support to guestmount (FUSE) module.
18 - virt-resize can now resize the content of partitions and logical
20 volumes in the guest, and we have better support for shrinking guests.
21 - Bash tab-completion script for guestfish.
23 - Add ZFS support to virt-rescue.
25 - New tool 'virt-make-fs' for creating filesystems with content.
27 - Allow suffixes on any guestfish number parameter, eg. "1M".
29 - guestfish 'man' command opens the manual page.
31 - guestfish supports a "heredoc" syntax for uploading files:
33 upload -<<_end_ /foo
34 content
35 _end_
36 - Some guestfish commands now print their output in octal or hex
38 where appropriate (RHBZ#583242).
39 - Allow dash prefix on guestfish command line. This ignores any
41 error from the second command: (RHBZ#578407)
42 guestfish -- cmd1 : -cmd2 : cmd3
43 - guestfish -h / help command now returns an error for non-existent
45 commands (RHBZ#597145).
46 - New 'supported' command in guestfish to list optional groups of
48 commands which are supported by the daemon / configuration.
49 - virt-inspector and guestfish -i now work for filenames which
51 contain spaces (RHBZ#507810).
52 - Change the protocol to use link-local addresses, to avoid
54 conflicting with any address that the host might be using
55 (RHBZ#588763).
56 - libguestfs now sets the correct time and timezone on filesystem
58 modifications.
59 - Sort the domains into alphabetical order in virt-df.
61 - Make mkfs-b command work for FAT and NTFS by mapping the blocksize
63 parameter to the cluster size (RHBZ#599464).
64 - Add version numbers to Perl modules (RHBZ#521674).
66 - Localization now works for all the libguestfs tools (RHBZ#559963).
68 - Tools now support filesystem-on-image VMs (RHBZ#590167).
70 - virt-list-partitions has a '-t' option to show the total size of disks.
72 - Include extra Augeas lenses in the supermin appliance (Matthew Booth).
74 - Add error and close callbacks.
76 - Add explicit close method in the Perl API.
78 - Multiple fixes for RHEL 5 compatibility.
80 - Multiple fixes for Debian/Ubuntu compatibility.
82 - Multiple revisions to improve the documentation.
84 Security
86 - Fix a potential DoS in virt-inspector and virt-v2v if a specially
87 crafted disk image contained a char device in place of one of the
88 configuration files that we read under /etc (RHBZ#582484).
