       libnbd-release-notes-1.10 - release notes for libnbd 1.10

DESCRIPTION

       These are the release notes for libnbd stable release 1.10.  This describes the major
       changes since 1.8.

       libnbd 1.10.0 was released on 23 September 2021.

   Security
       There were no security bugs found in libnbd during this release cycle.

       If you find a security issue, please read SECURITY in the source (online here:
       https://gitlab.com/nbdkit/libnbd/blob/master/SECURITY).  To find out about previous
       security issues in libnbd, see libnbd-security(3).

   New APIs
       No new APIs were added in 1.10.

   Enhancements to existing APIs
       nbd_get_uri(3) no longer returns service names (eg. "nbd://localhost:nbd").  Instead it
       always returns raw port numbers for portability.

       nbd_connect_uri(3) now supports "tls-certificates=DIR" query parameter, making it much
       easier to connect to servers using TLS with X.509 certificates.  Also error messages from
       this API have been improved in the case of some common URI user errors.

       Python "nbd.aio_connect" implements support for "AF_UNIX" sockets.

       Fix invalid use of "unsafe.Pointer" in Go bindings.

   Tools
       nbdcopy(1) now uses a default request size of 256K (instead of 32M).  This default
       performs better in most cases.

       nbdinfo(1) has a new --map --totals mode which displays a summary of the map.  Also new
       --can and --is options let you test export properties (eg. --is read-only).

       nbdinfo(1) --map option uses "data" instead of "allocated" because of ambiguity about what
       "allocated" means (Eric Blake, Nir Soffer).

       nbdinfo(1) shows the export size in both bytes and human units (like "1K").  The machine-
       parsable JSON output has not changed.

       nbdfuse(1) now supports efficient zeroing.  Note this requires Linux kernel ≥ 5.14.

       nbdsh(1) has new option -n which avoids creating the implicit handle "h".  Also new option
       -v which enables debugging.  Also the initial help banner is now context sensitive giving
       more relevant information depending on how nbdsh was invoked.

   Tests
       CI tests were greatly enhanced and many platform-specific fixes were made.  To view the
       latest CI tests and results see: https://gitlab.com/nbdkit/libnbd/-/pipelines (Martin
       Kletzander).

       Tests now use the new "GLIBC_TUNABLES" feature, replacing "MALLOC_CHECK_" on glibc ≥ 2.34
       (thanks Eric Blake, Siddhesh Poyarekar).

   Other improvements and bug fixes
       The nbdcopy(1) progress bar should be displayed more accurately in multithreaded mode.

   Documentation
       nbd_connect(3) and nbd_aio_connect(3) documentation has been revised and improved.

       More consistent option styling is used throughout the documentation.

       podwrapper.pl has been unified (almost) with the copy in nbdkit.

   Build
       configure.ac now uses spaces consistently, and has been modernized to support the latest
       autotools (Eric Blake).

       We now warn about large stack frames, and a few places which used large stack frames have
       been fixed.

       Continue fuzzing using AFL++.  Updated the fuzzing documentation.

       Fix building from git with --disable-ocaml.  As long as only "ocamlc" is installed, the
       generator should still be built and run (Martin Kletzander).
