NBD 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, Perl, Python, OCaml, Ruby or [new!] Tcl.
I'm pleased to announce the release of the new stable branch 1.4.
Download it here: http://download.libguestfs.org/nbdkit/1.4-stable/
There are many new features since the previous stable branch (1.2):
* You can write plugins in Tcl.
* Other new plugins: ext2, random, zero.
* New filters: blocksize, fua, log, nozero,
* Bash tab completion of nbdkit commands.
* TLS Pre-Shared Keys (PSK) authentication.
* We now default to the newstyle protocol, use -o to select oldstyle.
* On-demand ramping of thread pool.
* TRIM support in the file plugin.
* Reworked error handling.
* New can_zero, can_fua methods and better handling of FUA.
* New nbdkit_realpath function.
* nbdkit_parse_size rewritten.
* Better handling of shutdown path to ensure plugins can do long cleanups.
* New PKG_CHECK_VAR variables.
* Regression test for IPv6 connections.
* Of course numerous smaller bug fixes and improvements.
Thanks in particular to Eric Blake and Pino Toscano.
