These release notes only cover the differences from the previous stable/dev branch split (1.22.0).  For detailed changelogs, please see the git repository, or the ChangeLog file distributed in the tarball.
.SS "New features"
.IX Subsection "New features"
User-Mode Linux (\s-1UML\s0) can be used as an alternative backend (ie. instead of \s-1KVM\s0).  This improves performance especially when using libguestfs inside a \s-1VM\s0 (eg. in the cloud).  \s-1UML\s0 is supported as a first-class backend.  See \*(L"USER-MODE \s-1LINUX BACKEND\*(R"\s0 in \fBguestfs\fR\|(3) for how to use this.
.PP
\&\s-1ARM\s0 (32 bit) and \s-1PPC64\s0 are now fully supported.
.PP
\fITools\fR
.IX Subsection "Tools"
.PP
\&\fBvirt\-builder\fR\|(1) is a new tool for building virtual machine images.  It lets you rapidly and securely create guests and customize them.
.PP
New \fBvirt\-sysprep\fR\|(1) operations: Remove files in \fI/tmp\fR and \fI/var/tmp\fR. Remove \s-1RPM\s0 database files.  Change root and user passwords.  More log files are removed.  New operations which are not enabled by default: Create random UUIDs for filesystems.  Reset firewall rules.  (Wanlong Gao)
.PP
\&\fBvirt\-resize\fR\|(1) and virt-sysprep can now use URIs to specify a remote disk.
.PP
Use \f(CW\*(C`guestfish \-N filename=type\*(C'\fR to create a named disk image (instead of the default \fItest1.img\fR etc).
.PP
\&\fBvirt\-sparsify\fR\|(1) now tests if there is enough disk space to complete the operation, instead of possibly running out of space half way through.
.PP
\&\fBvirt\-format\fR\|(1) and \fBvirt\-make\-fs\fR\|(1): new \fI\-\-label\fR option for setting filesystem label.
.PP
virt-resize \fI\-\-no\-sparse\fR flag can be used to resize on to partitions and other targets that are not zeroed.
.PP
\fILanguage bindings\fR
.IX Subsection "Language bindings"
.PP
New bindings for the Go programming language.
.PP
\fI\s-1API\s0\fR
.IX Subsection "API"
.PP
Support for the systemd journal.
.PP
\&\f(CW\*(C`guestfs_add_drive_opts\*(C'\fR can now control the qemu caching mode through a new \f(CW\*(C`cachemode\*(C'\fR parameter.  You can select improved performance for temporary drives, or safety.
.PP
\&\f(CW\*(C`guestfs_set_label\*(C'\fR now works for \s-1XFS\s0 and btrfs.
.PP
New \s-1GUESTFS_EVENT_WARNING\s0 event for warning messages.
.PP
\fIInspection\fR
.IX Subsection "Inspection"
.PP
Better inspection of \s-1SUSE\s0 guests (Olaf Hering).
.PP
Better support for non-standard Windows \f(CW%systemroot\fR% (Matthew Booth).
.PP
Enhanced error reporting for Augeas errors.

.Sp
A denial of service was possible when inspecting certain guests.  The fix has been backported to 1.20 and 1.22 branches.

.IX Item "CVE-2013-4419"

The following packages are required to build libguestfs 1.24:
.IP "Augeas ≥ 1.0.0" 4
.IX Item "Augeas ≥ 1.0.0"
.PP
The following optional packages may be added to enhance functionality but are not required:
.IP "sd-journal" 4
.IX Item "sd-journal"
To read journal files from guests which use that.
.IP "url_mkcow" 4
.IX Item "url_mkcow"
For \s-1UML\s0 backend.
.IP "curl" 4
.IX Item "curl"
.PD 0
.IP "gpg" 4
.IX Item "gpg"
.IP "xz" 4
.IX Item "xz"
.PD
For virt-builder.
.IP "golang ≥ 1.1.1" 4
.IX Item "golang ≥ 1.1.1"
For Go language bindings.
.SS "内部"
.IX Subsection "内部"
New \f(CW\*(C`make check\-*\*(C'\fR rules replace \f(CW\*(C`make extra\-tests\*(C'\fR.  See \f(CW\*(C`make help\*(C'\fR and \fBguestfs\fR\|(3) for details.
.PP
Perl code can now be valgrinded.
.PP
Inspection code is now fuzz-tested.
.PP
\&\f(CW\*(C`make\*(C'\fR no longer recurses into the generator directory in every other directory.  This reduces the overhead of builds considerably.
.PP
Additional tests for Augeas, hivex.
.PP
Add a launch timeout of 20 minutes waiting for the appliance to start up.
.PP
Add a timeout (4 hours) to all tests so we can catch the case where qemu or other components hang.
.PP
Use kvmclock and \f(CW\*(C`\-cpu host\*(C'\fR.  This improves clock stability and overall performance.
.PP
\&\f(CW\*(C`./configure \-\-enable\-packet\-dump\*(C'\fR mode is fixed.
.PP
\&\f(CW\*(C`./configure \-\-enable\-valgrind\-daemon\*(C'\fR mode has been rewritten.  It is now feasible for developers to keep this flag enabled at all times.
.PP
Backends have been refactored to be modular (although they are not actually loadable modules).
.PP
When enabled, the network now uses resolver configuration (ie. /etc/resolv.conf) from the host.
