1 Release notes for FreeBSD 14.0.
3 This file describes new user-visible features, changes and updates relevant to
4 users of binary FreeBSD releases. Each entry should describe the change in no
5 more than several sentences and should reference manual pages where an
6 interested user can find more information. Entries should wrap after 80
7 columns. Each entry should begin with one or more commit IDs on one line,
8 specified as a comma separated list and/or range, followed by a colon and a
9 newline. Entries should be separated by a newline.
11 Changes to this file should not be MFCed.

14 The in-tree qat(4) driver has been replaced with Intel's QAT driver.
15 The new version provides additional interfaces to the chipset's
16 cryptographic and compression offload functionality.
18 This will have no visible change for most users; however, the new
19 driver does not support Atom C2000 chipsets. To preserve support for
20 those chipsets, the old driver has been renamed to qat_c2xxx and kept
21 in the tree. Users of qat(4) on C2000 hardware will thus need to
22 ensure that qat_c2xxx(4) is loaded instead of qat(4).

25 Boottrace is a new kernel-userspace interface for capturing trace
26 events during system boot and shutdown. Event annotations are
29 - The boot and shutdown paths in the kernel
30 - Some key system utilities (init(8), shutdown(8), reboot(8))
31 - rc(8) scripts (via boottrace(8))
33 In contrast to other existing boot-time tracing facilities like TSLOG,
34 Boottrace focuses on the ease of use and is aimed primarily at system
37 It is available in the default GENERIC kernel and can be enabled by
38 toggling a single sysctl(8) variable.
40 See boottrace(4) for more details.
43 Kernel TLS offload now supports receive-side offload of TLS 1.3.
46 if_stf now supports 6rd (RFC5969).

49 Add WiFi 6 support to wpa.

52 The default bell tone is now 800Hz. It may be set with kbdcontrol
53 again. There's devd integration for people wishing to use their sound
57 net.inet.tcp.nolocaltimewait enabled by default. It prevents
58 creation of timewait entries for TCP connections that were
62 sh(1) is now the default shell for the root user.
65 libncursesw has been split into libtinfow and libncursesw, linker
66 scripts should make it transparent for consumers. pkg-config files
67 are also now installed to ease ports detecting the ncurses setup from
71 LLVM's MemorySanitizer can now be used in amd64 kernels. See the
72 kmsan(9) manual page for more information.
75 LLVM's AddressSanitizer can now be used in amd64 kernels. See the
76 kasan(9) manual page for more information.

79 One True Awk has been updated to the latest from upstream
80 (20210727). All the FreeBSD patches, but one, have now been
81 either up streamed or discarded. Notable changes include:
82 o Locale is no longer used for ranges
84 o Better compatibility with gawk and mawk
86 The one FreeBSD change, likely to be removed in FreeBSD 14, is that
87 we still allow hex numbers, prefixed with 0x, to be parsed and
88 interpreted as hex numbers while all other awks (including one
89 true awk now) interpret them as 0 in line with awk's historic
92 A second change, less likely to be noticed, is the historic wart
93 if -Ft meaning to use hard tab characters as the field separator
94 is deprecated and will likely be removed in FreeBSD 14.
97 Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio
98 that can be used to increase the maximum I/O size for the NFS
99 server to any power of 2 up to 1Mbyte while the nfsd(8) is not running.
100 The FreeBSD NFS client can now be set to use a 1Mbyte I/O size
101 via the vfs.maxbcachebuf tunable and the Linux NFS client
102 can also do 1Mbyte I/O.
103 kern.ipc.maxsockbuf will need to be increased. A console
104 message will suggest a setting for it.
107 gconcat(8) has added support for appending devices to the device
108 not present at creation time.
111 Remove support for asymmetric cryptographic operations from
112 the kernel open cryptographic framework (OCF).
115 The NFSv4 client now uses the highest minor version of NFSv4
116 supported by the NFSv4 server by default instead of minor version 0,
118 The "minorversion" mount option may be used to override this default.
