1 Release notes for libguestfs 1.6.0
2 ----------------------------------
3 [updated to commit d75a2bff1264828f02b68a9c8bc7eb2521bd6684]
5 These release notes only cover the differences from the previous
6 stable/dev branch split (1.4.0). For detailed changelogs, please see
7 the git repository, or the ChangeLog file distributed in the tarball.
11 - Use a new method for creating and caching the appliance. This
12 greatly improves the performance of libguestfs.
14 - Support for guest inspection (like virt-inspector) via the ordinary
15 API and all language bindings. 'guestfish -i' option is as a side-
18 - Support for LUKS-encrypted guests.
22 - Progress messages (and progress bars in guestfish and virt-resize)
23 for certain long-running operations.
25 - virt-df is now much more efficient. Use '--one-per-guest' to restore
26 the old per-guest isolation behaviour.
28 - guestfish 'copy-in' and 'copy-out' commands for copying files and
29 directories recursively in and out of the guest.
31 - guestfish 'hexedit' command for doing binary edits to devices and
34 - Change guestfish -i syntax slightly to allow commands to be specified.
36 - guestfish '-d <domain>' for adding disks from libvirt domains.
38 - guestfish '-N' option supports several new prepared disk image types:
39 lvfs : disk with LV formatted with filesystem
42 bootrootlv : boot and root on LV
44 - guestfish 'more' and 'edit' commands now work with arbitrary files.
46 - guestfish '--echo-keys' option allows you to echo keys/passphrases
49 - Use virtio-serial for communications with the appliance. This
50 also has a major performance benefit.
52 - virt-edit '-b' option to create a backup of edited files.
54 - virt-edit '-e' option for non-interactive edits to files.
56 - Ability to capture core dumps from the appliance (thanks Matthew Booth).
58 - virt-rescue now shuts down cleanly (thanks Matthew Booth).
60 - Translations of manual pages.
73 - inspect-get-filesystems
74 - inspect-get-major-version
75 - inspect-get-minor-version
76 - inspect-get-mountpoints
77 - inspect-get-product-name
100 - Use size_t for loop iterators.
101 - Refactor the library code into separate files.
102 - Refactor the generator code into separate files.
103 - Generate guestfish commands.
105 error message size increased to 64K
106 send errno to library
107 - Add 'make bindist' to make a binary distribution.
111 - 633357 Updates to Spanish translation
112 - 629593 Dutch translation added
113 - 627556 Updates to Spanish translations of libguestfs
114 - 626843 Updates to Spanish translations
115 - 619793 [RFE] Need a way to determine if a particular block device is a logical volume
116 - 618556 virt-rescue return none zero value when exit
117 - 617200 mount operation failed and hung on some images which running in read-only mode
118 - 610880 libguestfs should set broader read perms on tmpdir, so works in some situations when executed with umask 077
119 - 571714 Running virt-df on disk image relabels it, so qemu can no longer write to it.
120 - 502533 Updated Polish translation of libguestfs
122 Release notes for libguestfs 1.4.0

126 stable/dev branch split (1.2.0). For detailed changelogs, please see
127 the git repository, or the ChangeLog file distributed in the tarball.
131 - guestfish lets you choose a prepared disk image, eg:
134 - Add write support to guestmount (FUSE) module.
136 - virt-resize can now resize the content of partitions and logical
137 volumes in the guest, and we have better support for shrinking guests.

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

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