I’m pleased to announce the next stable release of nbdkit.
NBD — Network Block Device — is a protocol for accessing Block Devices
(hard disks and disk-like things) over a Network. nbdkit is a toolkit
for creating NBD servers.
The key features are:
* Multithreaded NBD server written in C with good performance.
* Minimal dependencies for the basic server.
* Liberal license (BSD) allows nbdkit to be linked to proprietary
libraries or included in proprietary code.
* Well-documented, simple plugin API with a stable ABI guarantee.
Lets you export “unconventional” block devices easily.
* You can write plugins in C, Lua, Perl, Python, OCaml, Ruby,
[new!] shell script or Tcl.
* Filters can be stacked in front of plugins to transform the output.

- Magic config key allows simpler invocation of many plugins, eg:
nbdkit file file=foo
becomes:
nbdkit file foo
- data: Add disk2data.pl script to generate data parameters.
- data: Use ‘<file’ to inline a file.
- vddk: Use ‘-D vddk.diskinfo=1’ to enable extra debug information.
- tests: Use a helper function to refactor and simplify most tests.
- partition filter: Can handle > 128 GPT partitions.
- nbdkit can be compiled on the Haiku operating system
(François Revol).
- New nbdkit_parse_bool API for parsing boolean parameters (Eric Blake).
- log: Add logappend=[true|false] (Eric Blake).
- ocaml: New set_error and debug calls.
- Analyze code under AddressSanitizer and ThreadSanitizer and fix bugs
(Eric Blake).
- Analyze code under Coverity and fix bugs.
- Tests now run more quickly.
