Release notes for FreeBSD 14.0.
This file describes new user-visible features, changes and updates relevant to
users of binary FreeBSD releases. Each entry should describe the change in no
more than several sentences and should reference manual pages where an
interested user can find more information. Entries should wrap after 80
columns. Each entry should begin with one or more commit IDs on one line,
specified as a comma separated list and/or range, followed by a colon and a
newline. Entries should be separated by a newline.
Changes to this file should not be MFCed.
makefs(8) has ZFS support; it can create a ZFS pool, backed by a
single disk vdev, containing one or more datasets populated from
the staging directory.
The in-tree qat(4) driver has been replaced with Intel's QAT driver.
The new version provides additional interfaces to the chipset's
cryptographic and compression offload functionality.
This will have no visible change for most users; however, the new
driver does not support Atom C2000 chipsets. To preserve support for
those chipsets, the old driver has been renamed to qat_c2xxx and kept
in the tree. Users of qat(4) on C2000 hardware will thus need to
ensure that qat_c2xxx(4) is loaded instead of qat(4).
Boottrace is a new kernel-userspace interface for capturing trace
events during system boot and shutdown. Event annotations are
- The boot and shutdown paths in the kernel
- Some key system utilities (init(8), shutdown(8), reboot(8))
- rc(8) scripts (via boottrace(8))
In contrast to other existing boot-time tracing facilities like TSLOG,
Boottrace focuses on the ease of use and is aimed primarily at system
It is available in the default GENERIC kernel and can be enabled by
toggling a single sysctl(8) variable.
See boottrace(4) for more details.
Kernel TLS offload now supports receive-side offload of TLS 1.3.
if_stf now supports 6rd (RFC5969).
c1d255d3ffdb, 3968b47cd974, bd452dcbede6:
Add WiFi 6 support to wpa.
The default bell tone is now 800Hz. It may be set with kbdcontrol
again. There's devd integration for people wishing to use their sound
cards for the beep.
net.inet.tcp.nolocaltimewait enabled by default. It prevents
creation of timewait entries for TCP connections that were
sh(1) is now the default shell for the root user.
libncursesw has been split into libtinfow and libncursesw, linker
scripts should make it transparent for consumers. pkg-config files
are also now installed to ease ports detecting the ncurses setup from
LLVM's MemorySanitizer can now be used in amd64 kernels. See the
kmsan(9) manual page for more information.
LLVM's AddressSanitizer can now be used in amd64 kernels. See the
kasan(9) manual page for more information.
One True Awk has been updated to the latest from upstream
(20210727). All the FreeBSD patches, but one, have now been
either up streamed or discarded. Notable changes include:
o Locale is no longer used for ranges
o Various bugs fixed
o Better compatibility with gawk and mawk
The one FreeBSD change, likely to be removed in FreeBSD 14, is that
we still allow hex numbers, prefixed with 0x, to be parsed and
interpreted as hex numbers while all other awks (including one
true awk now) interpret them as 0 in line with awk's historic
A second change, less likely to be noticed, is the historic wart
if -Ft meaning to use hard tab characters as the field separator
is deprecated and will likely be removed in FreeBSD 14.
Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio
that can be used to increase the maximum I/O size for the NFS
server to any power of 2 up to 1Mbyte while the nfsd(8) is not running.
The FreeBSD NFS client can now be set to use a 1Mbyte I/O size
via the vfs.maxbcachebuf tunable and the Linux NFS client
can also do 1Mbyte I/O.
kern.ipc.maxsockbuf will need to be increased. A console
message will suggest a setting for it.
gconcat(8) has added support for appending devices to the device
not present at creation time.
Remove support for asymmetric cryptographic operations from
the kernel open cryptographic framework (OCF).
The NFSv4 client now uses the highest minor version of NFSv4
supported by the NFSv4 server by default instead of minor version 0,
for NFSv4 mounts.
The "minorversion" mount option may be used to override this default.
