NAME
       nbdkit-release-notes-1.12 - release notes for nbdkit 1.12

DESCRIPTION
       These are the release notes for nbdkit stable release 1.12.  This
       describes the major changes since 1.10.

       nbdkit 1.12.0 was released on 10th April	2019.

   New features
       New nbdkit-ssh-plugin(1)	which lets you turn any	disk image on a	remote
       Unix server accessible by ssh into an NBD source.

       New nbdkit-rate-filter(1) for bandwidth-limiting	connections.  Either
       single connections or the whole server can be bandwidth-limited,	and
       the limit can be	dynamically changed at runtime.

       New nbdkit-readahead-filter(1) improves performance when	reading
       sequentially from plugins with a	high request overhead like curl.

       New nbdkit-linuxdisk-plugin(1) lets you create complete ext2, ext3 or
       ext4 filesystems	in a GPT partitioned disk image, from a	local
       directory.  This	can be attached	to existing Linux VMs or used to
       create new ones from scratch.

       New nbdkit-noextents-filter(1) can make sparse disks appear fully
       allocated.

       Plugins can now be written in the Rust programming language, see
       nbdkit-rust-plugin(3).

       The old nbdkit-xz-plugin(1) has been removed.  Use

	nbdkit --filter=xz file	file.xz

       as a replacement.  This filter can be placed on top of other plugins
       such as curl (for decompressing a remote	web URL).

       "NBD_CMD_BLOCK_STATUS" has been implemented allowing clients to query
       which parts of the disk are allocated, holes or zeroes.	Plugins	and
       filters have been extended to supply this information in	many cases.
       This required adding minimal support for	NBD protocol Structured
       Replies,	"NBD_CMD_FLAG_REQ_ONE" and "NBD_CMD_FLAG_DF".  (Thanks to Eric
       Blake for extensive help	with this one.)

       nbdkit-vddk-plugin(1) has been updated to VDDK 6.7, but now also	works
       back as far as VDDK 5.1.1.  It supports extents,	flush and FUA.	Also
       added: new flags	"single-link" and "unbuffered".	 (Thanks to Martin
       Kletzander).

       The line	"All rights reserved." was removed from	the license, with the
       agreement of all	nbdkit contributors.  Note this	does not change	the
       license.

       "nbdkit_error" errors are printed in red	when writing to	the terminal,
       making them much	easier to see.

       "nbdkit_parse_size" rejects negative values, eg.
       "nbdkitA	memoryA	size=-100" (Nikolay Ivanets).

       nbdkit-curl-plugin(1) now supports cookies, password auth and proxies.
       It can also limit URLs to whitelisted protocols.	 This makes it broadly
       feature equivalent to and a replacement for the qemu curl block driver.

       nbdkit-partitioning-plugin(1) can now create MBR	logical	partitions.
       Previously it only supported 4 MBR primary partitions and if you	wanted
       more than that you had to use GPT.

       nbdkit-partition-filter(1) also supports	MBR logical partitions.

       nbdkit-python-plugin(3) creates plugins which are compatible with
       Python >= 3.7.

       Tests are now run under "MALLOC_CHECK_=1" and "MALLOC_PERTURB_=random".
       This causes some	tests to crash (silently) because of a shutdown	race
       which needs to be fixed.

       Test shell scripts now have a generic "requires"	function to skip tests
       if features are not present.

       C99 type	"bool" is now used in most places where	appropriate.

       The protocol and	connections code in the	server has been	split up
       because the single file had grown very large.  (Thanks to Eric Blake
       for helping with	protocol issues).
