752 Release notes for libguestfs 1.4.0
753 ----------------------------------
755 These release notes only cover the differences from the previous
756 stable/dev branch split (1.2.0). For detailed changelogs, please see
757 the git repository, or the ChangeLog file distributed in the tarball.
761 - guestfish lets you choose a prepared disk image, eg:
764 - Add write support to guestmount (FUSE) module.
766 - virt-resize can now resize the content of partitions and logical
767 volumes in the guest, and we have better support for shrinking guests.
769 - Bash tab-completion script for guestfish.
771 - Add ZFS support to virt-rescue.
773 - New tool 'virt-make-fs' for creating filesystems with content.
775 - Allow suffixes on any guestfish number parameter, eg. "1M".
777 - guestfish 'man' command opens the manual page.

784 - Some guestfish commands now print their output in octal or hex
785 where appropriate (RHBZ#583242).
787 - Allow dash prefix on guestfish command line. This ignores any
788 error from the second command: (RHBZ#578407)
789 guestfish -- cmd1 : -cmd2 : cmd3
791 - guestfish -h / help command now returns an error for non-existent
792 commands (RHBZ#597145).

795 commands which are supported by the daemon / configuration.
797 - virt-inspector and guestfish -i now work for filenames which
798 contain spaces (RHBZ#507810).
800 - Change the protocol to use link-local addresses, to avoid
801 conflicting with any address that the host might be using
804 - libguestfs now sets the correct time and timezone on filesystem
807 - Sort the domains into alphabetical order in virt-df.
809 - Make mkfs-b command work for FAT and NTFS by mapping the blocksize
810 parameter to the cluster size (RHBZ#599464).
812 - Add version numbers to Perl modules (RHBZ#521674).
814 - Localization now works for all the libguestfs tools (RHBZ#559963).
816 - Tools now support filesystem-on-image VMs (RHBZ#590167).
818 - virt-list-partitions has a '-t' option to show the total size of disks.
820 - Include extra Augeas lenses in the supermin appliance (Matthew Booth).
822 - Add error and close callbacks.
824 - Add explicit close method in the Perl API.
