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