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).
