9 These are the release notes for nbdkit stable release 1.6. This
10 describes the major changes since 1.4.
11
12 nbdkit 1.6.0 was released on 28th August 2018.
13
14 New features
15 • You can now write plugins in the Lua scripting language, see
16 nbdkit-lua-plugin(3).
17
18 • nbdkit and common plugins are now "63 bit clean": the maximum disk
19 size supported is 2⁶³-1 bytes, and the core server and plugins now
20 have additional tests to check this works, even on 32 bit machines.
21
22 • Multiple improvements to the nbdkit-file-plugin(1) to make zeroing
23 and trimming perform better, work correctly with block devices, and
24 work on older Linux kernels [Nir Soffer, Eric Blake].
25
26 • New nbdkit-pattern-plugin(1) generates a simple, fixed test pattern
27 for testing nbdkit filters and NBD clients.
28
29 • New nbdkit-truncate-filter(1) can: truncate or extend the size of
30 plugins, or round up or down the size to next multiple of a power
31 of 2. Useful for NBD clients like qemu which can only handle NBD
32 sizes which are a multiple of 512 bytes.
33
34 • New nbdkit-error-filter(1) which can be used to inject errors into
35 the protocol for testing how clients can handle and recover from
36 errors.
37
38 • New nbdkit-data-plugin(1) allows you to specify (small) disk images
39 directly on the command line.
40
41 • Enhanced error reporting in the Python plugin so full tracebacks
42 from errors are now displayed instead of being lost as before.
43
44 • "NBD_OPT_GO" now supported, so we can return errors when
45 negotiating the export name.
46
47 • Support for logging error messages to syslog.
48
49 • nbdkit can now be compiled with Clang (as well as GCC).
50
51 • nbdkit can now be compiled on FreeBSD.
52
53 • nbdkit-vddk-plugin(1) is compiled unconditionally. You no longer
54 need to install the proprietary VDDK to compile it.
55
56 • Debug messages now include the name of the filter when invoked from
57 a filter context.
58
59 • Debug flags (-D option) provides lightweight debugging for plugin
60 authors.
