DESCRIPTION

9       These are the release notes for libnbd stable release 1.4.  This
10       describes the major changes since 1.2.
11
12       libnbd 1.4.0 was released on 25 August 2020.
13
14   Security
15       There were no security issues found in this release.  If you find a
16       security issue, please read SECURITY in the source (online here:
17       https://gitlab.com/nbdkit/libnbd/blob/master/SECURITY).  To find out
18       about previous security issues in libnbd, see libnbd-security(3).
19
20   New APIs
21       nbd_set_opt_mode(3)
22       nbd_get_opt_mode(3)
23       nbd_aio_is_negotiating(3)
24           libnbd 1.4 adds a new “negotiating” state during NBD handshaking.
25           For backwards compatibility programs must request this before
26           starting the connection by calling nbd_set_opt_mode(3).  You can
27           find out if the connection is in this state by calling
28           nbd_aio_is_negotiating(3).
29
30           For an in-depth description of how this extra state can be used to
31           negotiate server options, see "CONTROLLING NEGOTIATION" in
32           libnbd(3).
33
34       nbd_aio_opt_abort(3)
35       nbd_opt_abort(3)
36           During the negotiating state, abort the connection.
37
38       nbd_aio_opt_go(3)
39       nbd_opt_go(3)
40           During the negotiating state, complete the handshake.
41
42       nbd_aio_opt_info(3)
43       nbd_opt_info(3)
44           During the negotiating state, request full information about the
45           server export.
46
47       nbd_aio_opt_list(3)
48       nbd_opt_list(3)
49           During the negotiating state, request the list of exports that the
50           server provides.
51
52       nbd_get_block_size(3)
53           Return the minimum, preferred or maximum block size constraints for
54           requests sent to the server.
55
56       nbd_get_canonical_export_name(3)
57           Return the canonical export name that the server defaults to.  This
58           information may only be available if you call nbd_set_full_info(3)
59           before connecting.
60
61       nbd_get_export_description(3)
62           Return the optional text description of the current export.  This
63           information may only be available if you call nbd_set_full_info(3)
64           before connecting.
65
66       nbd_set_full_info(3)
67       nbd_get_full_info(3)
68           Enable extended information about exports from the server.
69
70       Thanks: Eric Blake for all of the new APIs.
71
72   New features
73       Bindings are now available in the Go programming language.
74
75       FreeBSD and OpenBSD are now fully supported platforms.
76
77       Bash tab completion is available for all of the command line tools.
78
79   Documentation
80       Verbatim text in man pages that wrapped over several lines is now
81       typeset correctly.
82
83       Links within the documentation have been enhanced, and are now checked
84       for correctness.
85
86   Tools
87       New nbdcopy(1) tool lets you copy between an NBD server and a local
88       file, or stream to and from an NBD server.
89
90       New nbdinfo(1) tool lets you print extended information about an NBD
91       server’s exports (Eric Blake).
92
93   Tests
94       Test sockets are created in /tmp (instead of the local directory).
95       This stops the test suite from failing if the local directory path is
96       longer than the Unix domain socket maximum path length.
97
98   Other improvements and bug fixes
99       Trace messages have been improved: long strings are truncated, strings
100       with non-printable characters are escaped, and lists of strings are
101       printed.
102
103       The generator was split from a large single script into several small
104       files.  To build from git the OCaml bytecode compiler (ocamlc(1)) is
105       now required instead of the interpreter (ocaml(1)).
106
107       Long login names are supported in nbd_get_tls_username(3).
108
109       The handle name in nbdsh(1) is now set to "nbdsh" (instead of a
110       randomly generated name).
111
112       Compatibility with OCaml 4.10.0 and 4.11.0.
113
114       Python AIO buffer adds a new "is_zero" method allowing Python clients
115       to do sparsification when copying.
116
117       Compatibility with Python 3.9.
118
119       External C programs can now be compiled against libnbd’s build
120       directory using "../libnbd/run ./configure".
121
122       Honggfuzz can be used as another external fuzzing option.
123
124       Fix compilation with glibc 2.32 which deprecates "sys_errlist".
125
126       Many examples added or extended to demonstrate uses of the new APIs
127       (Eric Blake).
