=head1 NAME
nbdkit-release-notes-1.42 - release notes for nbdkit 1.42
=head1 DESCRIPTION
These are the release notes for nbdkit stable release 1.42.
This describes the major changes since 1.40.
nbdkit 1.42.0 was released on B<11 February 2025>.
=head2 Security
L<nbdkit-ip-filter(1)> has been fixed to close an information leak.
In an unusual configuration of the filter, it could leak the list of
exports to clients that are supposed to be blocked.
All past security issues and information about how to report new ones
can be found in L<nbdkit-security(1)>.
=head2 Plugins
L<nbdkit-ondemand-plugin(1)> now allows more characters to appear in
filenames. Colons are now allowed, so filenames containing MAC
addresses can be used, which is useful when using NBD in pre-boot
environments. Also add the C<share=true> option to allow sharing.
(Thanks Markus Hartung)
L<nbdkit-vddk-plugin(1)> now prints the default list of transports in
I<--dump-plugin> output. Also this plugin now handles partial chunks
correctly when reading extents for disks with a non-aligned size
(thanks Ming Xie).
=head2 Filters
New L<nbdkit-time-limit-filter(1)> can be used to specify the maximum
time limit for a connection. (See also the new I<--timeout> option
below).
New L<nbdkit-lzip-filter(1)> implements random access to
lzip-compressed files (Jan Felix Langenbach).
=head2 Language bindings
Multiple updates to L<nbdkit-rust-plugin(3)> to keep up to date with
latest changes in the Rust language (Alan Somers).
Fix crash that happened in L<nbdkit-ocaml-plugin(3)> plugins with
OCaml E<ge> 5 (thanks Guillaume Munch-Maccagnoni, Gabriel Scherer).
Also update the ocamldoc documentation. Fix more OCaml 5 deprecation
warnings.
Add support for Tcl 9.0 to L<nbdkit-tcl-plugin(3)>.
=head2 Server
nbdkit will now try to send the last plugin error message over the NBD
protocol to the client, to provide additional information. This
requires an NBD client which supports this, such as S<qemu E<ge> 2.12>
or S<libnbd E<ge> 1.22>.
New nbdkit I<--timeout> flag can be used as a security measure to
ensure that clients don't consume resources by opening lots of
connections and then not negotiating (or negotiating slowly) the full
NBD session.
New nbdkit I<--keepalive> option which enables TCP-level keepalives.
This is useful for detecting dead clients.
nbdkit I<--dump-config> output now includes C<timeout_option=yes|no>
and C<vsock_option=yes|no> reflecting whether the I<--timeout> and
I<--vsock> options are available.
