RELEASE NOTES FOR LIBGUESTFS 1.4

9       These release notes only cover the differences from the previous
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
13   New features
14        - guestfish lets you choose a prepared disk image, eg:
15            guestfish -N fs:ext4
16
17        - Add write support to guestmount (FUSE) module.
18
19        - 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
22        - Bash tab-completion script for guestfish.
23
24        - Add ZFS support to virt-rescue.
25
26        - New tool 'virt-make-fs' for creating filesystems with content.
27
28        - Allow suffixes on any guestfish number parameter, eg. "1M".
29
30        - guestfish 'man' command opens the manual page.
31
32        - guestfish supports a "heredoc" syntax for uploading files:
33            upload -<<_end_ /foo
34            content
35            _end_
36
37        - Some guestfish commands now print their output in octal or hex
38          where appropriate (RHBZ#583242).
39
40        - Allow dash prefix on guestfish command line.  This ignores any
41          error from the second command:                   (RHBZ#578407)
42            guestfish -- cmd1 : -cmd2 : cmd3
43
44        - guestfish -h / help command now returns an error for non-existent
45          commands (RHBZ#597145).
46
47        - New 'supported' command in guestfish to list optional groups of
48          commands which are supported by the daemon / configuration.
49
50        - virt-inspector and guestfish -i now work for filenames which
51          contain spaces (RHBZ#507810).
52
53        - 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
57        - libguestfs now sets the correct time and timezone on filesystem
58          modifications.
59
60        - Sort the domains into alphabetical order in virt-df.
61
62        - Make mkfs-b command work for FAT and NTFS by mapping the blocksize
63          parameter to the cluster size (RHBZ#599464).
64
65        - Add version numbers to Perl modules (RHBZ#521674).
66
67        - Localization now works for all the libguestfs tools (RHBZ#559963).
68
69        - Tools now support filesystem-on-image VMs (RHBZ#590167).
70
71        - virt-list-partitions has a '-t' option to show the total size of disks.
72
73        - Include extra Augeas lenses in the supermin appliance (Matthew Booth).
74
75        - Add error and close callbacks.
76
77        - Add explicit close method in the Perl API.
78
79        - Multiple fixes for RHEL 5 compatibility.
80
81        - Multiple fixes for Debian/Ubuntu compatibility.
82
83        - Multiple revisions to improve the documentation.
84
85   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).
