RELEASE NOTES FOR LIBGUESTFS 1.12

9       These release notes only cover the differences from the previous
10       stable/dev branch split (1.10.0).  For detailed changelogs, please see
11       the git repository, or the ChangeLog file distributed in the tarball.
12
13   New features
14       guestfish
15
16          - guestfish strings can use escapes,
17            eg. ><fs> write /foo "line 1\nline 2\n"
18
19          - guestfish write-append command can be used to append to files.
20
21          - Long-running file uploads and downloads can be cancelled through the
22            API or by hitting ^C in guestfish.
23
24          - New guestfish "display" command for displaying graphical files
25            inside guests.
26
27          - In guestfish, tab completion now works on /dev/mapper devices.
28
29       virt-inspector
30
31          - Inspection API can get an icon or logo for certain guests.
32
33          - virt-inspector includes the logo and hostname for certain guests.
34
35          - virt-inspector can now get the version and release numbers for RPM
36            packages.
37
38          - CentOS and Scientific Linux are now treated as separate distros by
39            the inspection API.
40
41       virt-resize
42
43          - virt-resize can now handle btrfs.
44
45          - New virt-resize --ntfsresize-force option allows Windows VMs to be
46            resized multiple times.
47
48       other virt tools
49
50          - guestfish, guestmount, virt-cat, virt-df, virt-edit, virt-filesystems,
51            virt-inspector, virt-ls and virt-rescue now allow you to use
52            "-d UUID" option to specify a guest by UUID.  This makes them more
53            robust to use from other programs.
54
55          - virt-ls -lR option allows complex file iteration and guest analysis.
56
57          - virt-win-reg supports HKEY_USERS\<SID> and HKEY_USERS\<username>.
58
59          - virt-win-reg new option --unsafe-printable-strings allows printable
60            strings to be displayed in the output (unsafely: read the documentation
61            before using).
62
63          - virt-edit has been rewritten in C.
64
65       API and language bindings
66
67          - Java is now completely supported.
68            See http://libguestfs.org/guestfs-java.3.html
69
70          - JRuby is supported via the Java bindings.
71
72          - guestfs_close now appears in trace messages.
73
74          - Python binding adds explicit g.close() method.
75
76          - Python programs can now use the new event API.
77
78          - Python GIL is released during libguestfs calls, allowing multithreaded
79            Python programs to work properly.
80
81          - 9pfs (Plan 9 filesystems exported from the host) are now supported.
82
83          - Add -DGUESTFS_WARN_DEPRECATED=1 to warn about use of deprecated API
84            functions in C programs.
85
86          - New manual page guestfs-recipes(1) with recipes.
87
88          - mkfs-opts can now set inode size and sector size on created filesystems
89            (thanks Nikita Menkovich).
90
91          - guestfs_last_errno is now accessible from OCaml (as g#last_errno ()).
92
93   Security
94        - optargs_bitmask is checked even for calls that have no optional
95          arguments.  This closes a possible exploit in the daemon from
96          untrusted callers.
97
98   New APIs
99         btrfs-filesystem-resize, get-pgroup, inspect-get-icon, is-zero,
100         is-zero-device, list-9p, list-dm-devices, mount-9p, ntfsresize-opts,
101         set-pgroup, write-append
102
103   Internals
104        - Coverity (a static analysis tool) was run across the codebase and
105          many fixes were made.
106
107        - Generator can handle functions that return RBufferOut and have
108          optional arguments.
109
110        - Compatible with Perl 5.14.
111
112        - Compatible with gcc 4.6.
113
114        - Perform safety checks on QEMU.
115
116        - C API tests can now fully test calls that have optional arguments.
117

119
120        - po-docs directory now covers all man pages.
