libguestfs/RELEASE-NOTES

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
the git repository, or the ChangeLog file distributed in the tarball.

New features

 - Use a new method for creating and caching the appliance.  This
   greatly improves the performance of libguestfs.

 - 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.

 - 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.

 - Change guestfish -i syntax slightly to allow commands to be specified.

 - 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.

 - 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).

 - Translations of manual pages.

Release notes for libguestfs 1.4.0
----------------------------------

These release notes only cover the differences from the previous
stable/dev branch split (1.2.0).  For detailed changelogs, please see
the git repository, or the ChangeLog file distributed in the tarball.

New features

 - guestfish lets you choose a prepared disk image, eg:
     guestfish -N fs:ext4

 - Add write support to guestmount (FUSE) module.

 - virt-resize can now resize the content of partitions and logical
   volumes in the guest, and we have better support for shrinking guests.

 - Bash tab-completion script for guestfish.

 - Add ZFS support to virt-rescue.

 - New tool 'virt-make-fs' for creating filesystems with content.

 - Allow suffixes on any guestfish number parameter, eg. "1M".

 - guestfish 'man' command opens the manual page.

 - guestfish supports a "heredoc" syntax for uploading files:
     upload -<<_end_ /foo
     content
     _end_

 - Some guestfish commands now print their output in octal or hex
   where appropriate (RHBZ#583242).

 - Allow dash prefix on guestfish command line.  This ignores any
   error from the second command:                   (RHBZ#578407)
     guestfish -- cmd1 : -cmd2 : cmd3

 - guestfish -h / help command now returns an error for non-existent
   commands (RHBZ#597145).

 - New 'supported' command in guestfish to list optional groups of
   commands which are supported by the daemon / configuration.

 - virt-inspector and guestfish -i now work for filenames which
   contain spaces (RHBZ#507810).

 - Change the protocol to use link-local addresses, to avoid
   conflicting with any address that the host might be using
   (RHBZ#588763).

 - libguestfs now sets the correct time and timezone on filesystem
   modifications.

 - Sort the domains into alphabetical order in virt-df.

 - Make mkfs-b command work for FAT and NTFS by mapping the blocksize
   parameter to the cluster size (RHBZ#599464).

 - Add version numbers to Perl modules (RHBZ#521674).

 - Localization now works for all the libguestfs tools (RHBZ#559963).

 - Tools now support filesystem-on-image VMs (RHBZ#590167).

 - virt-list-partitions has a '-t' option to show the total size of disks.

 - Include extra Augeas lenses in the supermin appliance (Matthew Booth).

 - Add error and close callbacks.

 - Add explicit close method in the Perl API.

 - Multiple fixes for RHEL 5 compatibility.

 - Multiple fixes for Debian/Ubuntu compatibility.

 - Multiple revisions to improve the documentation.

Security

 - Fix a potential DoS in virt-inspector and virt-v2v if a specially
   crafted disk image contained a char device in place of one of the
   configuration files that we read under /etc (RHBZ#582484).
