+Release notes for libguestfs 1.14.0
-----------------------------------
-LAST UPDATED TO COMMIT 76bd81820f50a390b7e853d65f41b29a37e63f43
+These release notes only cover the differences from the previous
+stable/dev branch split (1.12.0). For detailed changelogs, please see
+the git repository, or the ChangeLog file distributed in the tarball.
+
+New features
+
+ Erlang bindings.
+
+ virt-alignment-scan is a new tool to check the alignment of
+ partitions within virtual machines or disk images.
+
+ virt-sparsify is a new tool to make virtual machine disk images
+ sparse.
+
+ virt-sysprep is a new tool to make cloning guests from a template
+ simpler.
+
+ guestfish:
+
+ - New commands setenv, unsetenv, to set environment variables.
+
+ - The input file and line number is printed in error messages.
+
+ - guestfish progress bars are now a "mini-library" used by other
+ tools too.
+
+ guestmount:
+
+ - the --live option (for access to live VMs) now works.
+
+ virt-cat:
+
+ - virt-cat can now handle Windows paths and drive letters (RHBZ#693359).
+
+ virt-filesystems:
+
+ - the MBR partition type byte is displayed in --long output.
+
+ virt-make-fs:
+
+ - virt-make-fs now sets the MBR partition type byte correctly,
+ improving compatibility with Windows (RHBZ#746295).
+
+ virt-resize:
+
+ - virt-resize can now work with guests using extended and logical
+ partitions, in particular Ubuntu guests.
+
+ - virt-resize can now align the first partition of Windows guests,
+ improving performance. The new virt-resize --align-first option
+ controls this behaviour.
+
+ - The virt-resize --machine-readable flag makes it possible to use
+ virt-resize from other programs.
+
+ - Partitions are now aligned to 128 sectors (usually 64K) by
+ default. This improves efficiency on high-end storage. The new
+ virt-resize --alignment option allows the alignment to be
+ adjusted.
+
+ virt-win-reg:
+
+ - The syntax for deleting registry keys and values is documented
+ in the man page (RHBZ#737944).
+
+ library:
+
+ - non-printing characters are escaped correctly in debug output.
+
+ - GUESTFS_EVENT_ENTER is a new event type generated whenever a
+ libguestfs function is called.
+
+ - the library contains systemtap/DTrace probes.
+
+ - the library can now be compiled without hivex (RHBZ#723474).
+
+ inspection:
+
+ - Improve detection of Windows disks.
+
+ - Adds support for:
+ ttylinux - a minimal Linux
+ Mageia (thanks Michael Scherer)
+ OpenSUSE and zypper (thanks Michael Scherer, Vincent Untz)
+ Ubuntu logos (thanks Michael Scherer)
+ NetBSD and pkgsrc (thanks Michael Scherer)
+
+ - Handle some guest types that use /dev/root in /etc/fstab.
+
+ - Fix handling of guests with > 26 disks (thanks Matthew Booth)
+
+ - Add support for guests with HP Smart Array disks (thanks Matthew Booth)
+
+ febootstrap:
+
+ - FEBOOTSTRAP_KERNEL, FEBOOTSTRAP_MODULES environment variables can
+ be set in order to choose which kernel to use for the appliance.
+
+ misc:
+
+ - ArchLinux support now working with Linux 3.0 (thanks Erik Nolte)
+
+ - libvirt disks marked <readonly/> are now added readonly when
+ using the virt-tools '-d' option.
+
+Security
+
+ (no security problems were found or fixed in this release)
+
+New APIs
+
+ compress-out, compress-device-out, copy-device-to-device,
+ copy-device-to-file, copy-file-to-device, copy-file-to-file,
+ get-smp, part-to-partnum, set-smp.
+
+ The mount API no longer implicitly adds -o sync,noatime options.
+
+ add-domain has a new 'readonlydisk' optional parameter to control
+ how <readonly/> disks are handled.
+
+Internals
+
+ - Coverity was run on the source and more bugs were identified and
+ fixed.
+
+ - PCRE library is now required to build libguestfs.
+
+ - APIC is now the default for the appliance. You can also enable
+ SMP support in the appliance.
+
+ - OCaml bindings now correctly acquire GC lock during callbacks.
+
+ - Out of tree builds should now work correctly (thanks Hilko Bengen).
+
+ - ./configure --with-extra="..." can be used by packagers to set
+ the extra version string.
+
+ - zero, zero-device APIs: if the blocks already contain zeroes,
+ don't write zeroes, so that we don't unnecessarily make the
+ underlying storage non-sparse.
+
+ - is-zero, is-zero-device APIs: optimize these so zero detection is
+ faster.
+
+Bugs fixed
+
+ - 748266 libguestfs should detect versions of qemu which require -machine pc option
+ - 747290 libguestfs ignores <readonly/> in libvirt XML
+ - 747287 Misleading error message when permission denied opening a disk image
+ - 746295 virt-make-fs doesn't set partition ID
+ - 744795 guestmount --live is not usable
+ - 737944 virt-win-reg hyphen (delete key) syntax may be wrong, and is not documented
+ - 733297 ruby event handlers fail with "exception in callback: wrong argument type Proc (expected Data)"
+ - 731744 libguestfs should escape special/non-printing characters in debug output
+ - 729887 appliance crashes running aug_init with flags=4
+ - 729075 libguestfs confuses Hp_recovery partition with Windows root filesystem
+ - 727178 error: luks_open: cryptsetup: error while loading shared libraries: libfipscheck.so.1: cannot open shared object file: No such file or directory
+ - 726739 libguestfs: error: aug_get: no matching node, trying to find hostname
+ - 723474 If hivex and/or pcre not installed, libguestfs fails to compile
+ - 693359 virt-cat and virt-edit don't handle case sensitive NTFS paths properly
+ - 678231 virt-inspector reports unknown filesystem UUID
+ - 671082 libguestfs does not work with kernel-rt
+ - 666578 libguestfs: unknown filesystem label SWAP-sda2
+ - 642821 virt-resize falls over on a disk image with a logical swap partition
