       nbdkit-release-notes-1.38 - release notes for nbdkit 1.38

DESCRIPTION

       These are the release notes for nbdkit stable release 1.38.  This describes the major changes since 1.36.

       nbdkit 1.38.0 was released on 5 April 2024.

   Security
       No security issues were found in this release.

       All past security issues and information about how to report new ones can be found in nbdkit-security(1).

   Plugins
       New nbdkit-gcs-plugin(1) providing support for Google Cloud Storage (Mykola Ivanets).

       nbdkit-data-plugin(1), nbdkit-memory-plugin(1), nbdkit-floppy-plugin(1), nbdkit-iso-plugin(1),
       nbdkit-sparse-random-plugin(1) and nbdkit-torrent-plugin(1) all now advertise suitable minimum, preferred
       and maximum block sizes, which means clients should be able to access them more efficiently.

       nbdkit-vddk-plugin(1) now supports VDDK up to version 8.0.2.1.

       nbdkit-S3-plugin(1) now reads sensitive tokens as passwords, allowing more flexibility on how to safely
       pass them to nbdkit.

   Filters
       New nbdkit-readonly-filter(1) which allows more fine-grained control over whether a plugin is read-only
       (and also to change it at runtime) compared to the normal nbdkit -r command line option.

   Language bindings
       nbdkit-python-plugin(3) adds bindings for "nbdkit.is_tls", "nbdkit.stdio_safe", "nbdkit.nanosleep"
       "nbdkit.peer_pid", "nbdkit.peer_uid", "nbdkit.peer_gid", "nbdkit.peer_security_context",
       "nbdkit.read_password".

       nbdkit-ocaml-plugin(3) implements zero-copy pread and pwrite calls.  This change is not backwards
       compatible for OCaml plugin code.  (Thanks Nicolas Ojeda Bar, Anil Madhavapeddy, Simon Cruanes).

       nbdkit-ocaml-plugin also adds extra OCaml version information to --dump-plugin output; and adds an
       example of how to use debug flags.

       nbdkit-rust-plugin(3) minimum Rust version (MSRV) increased to 1.63.0.  Various issues found by clippy
       have been fixed (Alan Somers).

   Server
       New --no-meta-contexts (--no-mc) option which stops the server from advertising metadata contexts,
       improving interoperability testing (Eric Blake).

       nbdkit --dump-plugin outputs additional fields: The internal "soext", either "so" or "dll" so you can
       tell what plugin/filter extension the server is looking for.  The "max_api_version" is the maximum plugin
       API version supported.

   Bug fixes
       Fix compilation with GCC 14 (Florian Weimer).

       Fix the default block size exposed by nbdkit-S3-plugin(1), fix the zero callback, and other bug fixes
       (Mykola Ivanets).

       nbdkit-luks-filter(1) could enter an infinite loop in some error cases (Wilko Nienhaus).

       Several plugins would crash or behave strangely if no parameters were passed.  These have been fixed and
       a regression test added.

   Documentation
       Update fio benchmarking documentation (Eric Blake).

       Add example of how to export a variable to --run subcommands (Eric Blake).

   Tests
       Fix Cirros CI tests (Peter Krempa).

   Build
       bash ≥ 4 is required.  (This was always true, but now the ./configure script checks it.)

       You can now use both environment variables "NBDKIT_VALGRIND=1 NBDKIT_GDB=1" together to run valgrind and
       gdbserver, in order to debug valgrinded nbdkit and plugins.

   Internals
       Important internal structs now contain magic values which are checked by optional assertions, improving
       type safety.
