guestfs-release-notes - libguestfs リリースノート
Please note that virt-v2v, virt-p2v and the boot analysis tools were moved out of the libguestfs package / repository into separate projects. See:
Those projects are now on a separate release cycle. Release notes are published separately.
Add support for the Vala language (Corentin Noël).
Add support for the Rust language (Hiroyuki Katsura, sponsored by Google Summer of Code).
Reproducible builds (Chris Lamb).
Advanced Format disks (which use 4K sectors) can now be processed by libguestfs. Use the new optional "blocksize" parameter to "guestfs_add_drive_opts", and the --blocksize option added to several tools (Nikolay Ivanets).
Windows CompactOS (NTFS file compression) is now supported.
New features in existing tools
Advanced machine readable output in various virt tools now supports JSON output, and writing logs to a numbered file descriptor (Pino Toscano).
virt-filesystems tool now more accurately reports filesystem total size, in the case where for example the filesystem does not occupy the whole of its containing device (Pino Toscano).
Language bindings
Python ≥ 2.7 is required.
Python bindings are now more extensively tested (Hiroyuki Katsura).
Python bindings should now work with Python ≥ 3.8.
Multiple fixes to avoid crashes in the Python bindings (Sam Eiderman).
OCaml bindings are compiled with "-DCAML_NAME_SPACE" to ensure no non-caml_-namespaced symbols are used (Pino Toscano).
OCaml bindings should now work with OCaml 4.09 and 4.10.
Erlang has deprecated the old "erl_interface" library which we use for Erlang bindings. It will be removed in OTP 22, which will permanently break Erlang support unless someone steps forward to update the Erlang bindings in libguestfs.
Fix compatibility with newer cgo for Go bindings (Tomáš Golembiovský).
Go API error handling is now more idiomatic (Csaba Henk).
Update documentation about how to handle boolean parameters in Ruby bindings (Csaba Henk).
Inspection
Libguestfs can now extract icons for Gentoo, newer SUSE and OpenMandriva guests. Improved extraction of RHEL icons. (Pino Toscano).
Inspection returns the osinfo IDs of newer Windows versions, and rolling Linux distros (Pino Toscano).
OpenMandriva is now detected (Bernhard Rosenkränzer).
Arch Linux detection improvements (Pino Toscano).
Architectures and platforms
Libguestfs can now be compiled on OpenMandriva (Bernhard Rosenkränzer).
Ubuntu fix for enabling network support (Ioanna Alifieraki).
Other
Use of deprecated libguestfs APIs will now cause compiler deprecation warnings by default, whereas previously you have to enable these warnings. To turn off these warnings use "-DGUESTFS_NO_WARN_DEPRECATED=1". A new feature is that you can now disable deprecated APIs completely if you want, using "-DGUESTFS_NO_DEPRECATED=1" (Pino Toscano).
Fix hostname in virt-builder templates (Pino Toscano).
The single large release notes file is now split into multiple documents organized by version.
The "--key" option of several tools was broken, especially if you tried to use the option to pass multiple keys. This has been fixed and a regression test added.
Augeas exceptions occurring in daemon (eg. during inspection) will now produced detailed errors (Pino Toscano).
No security issues were found in this release.
New APIs
"luks_uuid" returns the UUID of a LUKS device (Pino Toscano).
Other API changes
Cope with new output from the "btrfs scrub" command. There is no visible change at the API level.
New optional parameter "blocksize" added to "guestfs_add_drive_opts" to support Advanced Format disks (Nikolay Ivanets).
Minimum version of Augeas required is 1.2.0 (Pino Toscano).
"common/" subdirectory is now a git submodule shared with the virt-v2v project.
Supermin ≥ 5.1.18 is required.
There were several bugs in libvirt 5.10.0 and 6.0 which affected libguestfs. It is highly advisable to use libvirt 6.1 where these bugs are fixed (versions of libvirt < 5.10.0 are also fine).
Many gnulib modules which we were not using or which we used in only a few places have been removed (Pino Toscano).
Multiple fixes for builddir != sourcedir builds (Pino Toscano).
A new "bundled/" subdirectory contains one bundled library that we currently use, "ocaml-augeas" (Pino Toscano).
Fix compatibility issues when being compiled with GCC 10.
When linking OCaml programs, automake silent rules and the "V=1" flag are both now obeyed (Pino Toscano).
The "guestfs_device_index" API was reimplemented in library code instead of in the daemon. There should be no observable effect of this change.
Since Linux 5.6 enumerates "/dev/sdX" devices in parallel, libguestfs was changed to map API device names to appliance device names, and then do the reverse mapping when returning names from the appliance. Hopefully this should have no observable effect, but can produce somewhat confusing debugging messages since device names in the debug might not match device names passed in to APIs. Furthermore the "root=UUID=..." option is always passed to the appliance (instead of naming the device containing the root filesystem).
We expect to move from the Zanata service to the Weblate service for translated strings. For more information see https://bugzilla.redhat.com/1787301
