DESCRIPTION

9       These are the release notes for nbdkit stable release 1.12.  This
10       describes the major changes since 1.10.
11
12       nbdkit 1.12.0 was released on 10th April 2019.
13
14   New features
15       New nbdkit-ssh-plugin(1) which lets you turn any disk image on a remote
16       Unix server accessible by ssh into an NBD source.
17
18       New nbdkit-rate-filter(1) for bandwidth-limiting connections.  Either
19       single connections or the whole server can be bandwidth-limited, and
20       the limit can be dynamically changed at runtime.
21
22       New nbdkit-readahead-filter(1) improves performance when reading
23       sequentially from plugins with a high request overhead like curl.
24
25       New nbdkit-linuxdisk-plugin(1) lets you create complete ext2, ext3 or
26       ext4 filesystems in a GPT partitioned disk image, from a local
27       directory.  This can be attached to existing Linux VMs or used to
28       create new ones from scratch.
29
30       New nbdkit-noextents-filter(1) can make sparse disks appear fully
31       allocated.
32
33       Plugins can now be written in the Rust programming language, see
34       nbdkit-rust-plugin(3).
35
36       The old nbdkit-xz-plugin has been removed.  Use
37
38        nbdkit --filter=xz file file.xz
39
40       as a replacement.  This filter can be placed on top of other plugins
41       such as curl (for decompressing a remote web URL).
42
43       "NBD_CMD_BLOCK_STATUS" has been implemented allowing clients to query
44       which parts of the disk are allocated, holes or zeroes.  Plugins and
45       filters have been extended to supply this information in many cases.
46       This required adding minimal support for NBD protocol Structured
47       Replies, "NBD_CMD_FLAG_REQ_ONE" and "NBD_CMD_FLAG_DF".  (Thanks to Eric
48       Blake for extensive help with this one.)
49
50       nbdkit-vddk-plugin(1) has been updated to VDDK 6.7, but now also works
51       back as far as VDDK 5.1.1.  It supports extents, flush and FUA.  Also
52       added: new flags "single-link" and "unbuffered".  (Thanks to Martin
53       Kletzander).
54
55       The line "All rights reserved." was removed from the license, with the
56       agreement of all nbdkit contributors.  Note this does not change the
57       license.
58
59       "nbdkit_error" errors are printed in red when writing to the terminal,
60       making them much easier to see.
61
62       "nbdkit_parse_size" rejects negative values, eg.
63       "nbdkit memory size=-100" (Nikolay Ivanets).
64
65       nbdkit-curl-plugin(1) now supports cookies, password auth and proxies.
66       It can also limit URLs to whitelisted protocols.  This makes it broadly
67       feature equivalent to and a replacement for the qemu curl block driver.
68
69       nbdkit-partitioning-plugin(1) can now create MBR logical partitions.
70       Previously it only supported 4 MBR primary partitions and if you wanted
71       more than that you had to use GPT.
72
73       nbdkit-partition-filter(1) also supports MBR logical partitions.
74
75       nbdkit-python-plugin(3) creates plugins which are compatible with
76       Python >= 3.7.
77
78       Tests are now run under "MALLOC_CHECK_=1" and "MALLOC_PERTURB_=random".
79       This causes some tests to crash (silently) because of a shutdown race
80       which needs to be fixed.
81
82       Test shell scripts now have a generic "requires" function to skip tests
83       if features are not present.
84
85       C99 type "bool" is now used in most places where appropriate.
86
87       The protocol and connections code in the server has been split up
88       because the single file had grown very large.  (Thanks to Eric Blake
89       for helping with protocol issues).
