•

You can now write plugins in the Lua scripting language, see nbdkit-lua-plugin(3).

•

nbdkit and common plugins are now "63 bit clean": the maximum disk size supported is 2⁶³-1 bytes, and the core server and plugins now have additional tests to check this works, even on 32 bit machines.

•

Multiple improvements to the nbdkit-file-plugin(1) to make zeroing and trimming perform better, work correctly with block devices, and work on older Linux kernels [Nir Soffer, Eric Blake].

•

New nbdkit-pattern-plugin(1) generates a simple, fixed test pattern for testing nbdkit filters and NBD clients.

•

New nbdkit-truncate-filter(1) can: truncate or extend the size of plugins, or round up or down the size to next multiple of a power of 2. Useful for NBD clients like qemu which can only handle NBD sizes which are a multiple of 512 bytes.

•

New nbdkit-error-filter(1) which can be used to inject errors into the protocol for testing how clients can handle and recover from errors.

•

New nbdkit-data-plugin(1) allows you to specify (small) disk images directly on the command line.

•

Enhanced error reporting in the Python plugin so full tracebacks from errors are now displayed instead of being lost as before.

•

"NBD_OPT_GO" now supported, so we can return errors when negotiating the export name.

•

Support for logging error messages to syslog.

•

nbdkit can now be compiled with Clang (as well as GCC).

•

nbdkit can now be compiled on FreeBSD.

•

nbdkit-vddk-plugin(1) is compiled unconditionally. You no longer need to install the proprietary VDDK to compile it.

•

Debug messages now include the name of the filter when invoked from a filter context.

•

Debug flags (-D option) provides lightweight debugging for plugin authors.
