RELEASE NOTES FOR LIBGUESTFS 1.14

9       These release notes only cover the differences from the previous
10       stable/dev branch split (1.12.0).  For detailed changelogs, please see
11       the git repository, or the ChangeLog file distributed in the tarball.
12
13   New features
14         Erlang bindings.
15
16         virt-alignment-scan is a new tool to check the alignment of
17         partitions within virtual machines or disk images.
18
19         virt-sparsify is a new tool to make virtual machine disk images
20         sparse.
21
22         virt-sysprep is a new tool to make cloning guests from a template
23         simpler.
24
25       guestfish
26
27          - New commands setenv, unsetenv, to set environment variables.
28
29          - The input file and line number is printed in error messages.
30
31          - guestfish progress bars are now a "mini-library" used by other
32            tools too.
33
34       guestmount
35
36          - the --live option (for access to live VMs) now works.
37
38       virt-cat
39
40          - virt-cat can now handle Windows paths and drive letters (RHBZ#693359).
41
42       virt-filesystems
43
44          - the MBR partition type byte is displayed in --long output.
45
46       virt-make-fs
47
48          - virt-make-fs now sets the MBR partition type byte correctly,
49            improving compatibility with Windows (RHBZ#746295).
50
51       virt-resize
52
53          - virt-resize can now work with guests using extended and logical
54            partitions, in particular Ubuntu guests.
55
56          - virt-resize can now align the first partition of Windows guests,
57            improving performance.  The new virt-resize --align-first option
58            controls this behaviour.
59
60          - The virt-resize --machine-readable flag makes it possible to use
61            virt-resize from other programs.
62
63          - Partitions are now aligned to 128 sectors (usually 64K) by
64            default.  This improves efficiency on high-end storage.  The new
65            virt-resize --alignment option allows the alignment to be
66            adjusted.
67
68       virt-win-reg
69
70          - The syntax for deleting registry keys and values is documented
71            in the man page (RHBZ#737944).
72
73       library
74
75          - non-printing characters are escaped correctly in debug output.
76
77          - GUESTFS_EVENT_ENTER is a new event type generated whenever a
78            libguestfs function is called.
79
80          - the library contains systemtap/DTrace probes.
81
82          - the library can now be compiled without hivex (RHBZ#723474).
83
84       inspection
85
86          - Improve detection of Windows disks.
87
88          - Adds support for:
89                ttylinux - a minimal Linux
90                Mageia (thanks Michael Scherer)
91                OpenSUSE and zypper (thanks Michael Scherer, Vincent Untz)
92                Ubuntu logos (thanks Michael Scherer)
93                NetBSD and pkgsrc (thanks Michael Scherer)
94
95          - Handle some guest types that use /dev/root in /etc/fstab.
96
97          - Fix handling of guests with > 26 disks (thanks Matthew Booth)
98
99          - Add support for guests with HP Smart Array disks (thanks Matthew Booth)
100
101       febootstrap
102
103          - FEBOOTSTRAP_KERNEL, FEBOOTSTRAP_MODULES environment variables can
104            be set in order to choose which kernel to use for the appliance.
105
106       misc
107
108          - ArchLinux support now working with Linux 3.0 (thanks Erik Nolte)
109
110          - libvirt disks marked <readonly/> are now added readonly when
111            using the virt-tools '-d' option.
112
113   Security
114         (no security problems were found or fixed in this release)
115
116   New APIs
117         compress-out, compress-device-out, copy-device-to-device,
118         copy-device-to-file, copy-file-to-device, copy-file-to-file,
119         get-smp, part-to-partnum, set-smp.
120
121         The mount API no longer implicitly adds -o sync,noatime options.
122
123         add-domain has a new 'readonlydisk' optional parameter to control
124         how <readonly/> disks are handled.
125
126   Internals
127        - Coverity was run on the source and more bugs were identified and
128          fixed.
129
130        - PCRE library is now required to build libguestfs.
131
132        - APIC is now the default for the appliance.  You can also enable
133          SMP support in the appliance.
134
135        - OCaml bindings now correctly acquire GC lock during callbacks.
136
137        - Out of tree builds should now work correctly (thanks Hilko Bengen).
138
139        - ./configure --with-extra="..." can be used by packagers to set
140          the extra version string.
141
142        - zero, zero-device APIs: if the blocks already contain zeroes,
143          don't write zeroes, so that we don't unnecessarily make the
144          underlying storage non-sparse.
145
146        - is-zero, is-zero-device APIs: optimize these so zero detection is
147          faster.
148
149   Bugs fixed
150        - 748266 libguestfs should detect versions of qemu which require -machine pc option
