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

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

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

68 One True Awk has been updated to the latest from upstream
69 (20210727). All the FreeBSD patches, but one, have now been
70 either up streamed or discarded. Notable changes include:
71 o Locale is no longer used for ranges
73 o Better compatibility with gawk and mawk
75 The one FreeBSD change, likely to be removed in FreeBSD 14, is that
76 we still allow hex numbers, prefixed with 0x, to be parsed and
77 interpreted as hex numbers while all other awks (including one
78 true awk now) interpret them as 0 in line with awk's historic
81 A second change, less likely to be noticed, is the historic wart
82 if -Ft meaning to use hard tab characters as the field separator
83 is deprecated and will likely be removed in FreeBSD 14.
86 Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio
87 that can be used to increase the maximum I/O size for the NFS
88 server to any power of 2 up to 1Mbyte while the nfsd(8) is not running.
89 The FreeBSD NFS client can now be set to use a 1Mbyte I/O size
90 via the vfs.maxbcachebuf tunable and the Linux NFS client
91 can also do 1Mbyte I/O.
92 kern.ipc.maxsockbuf will need to be increased. A console
93 message will suggest a setting for it.
96 gconcat(8) has added support for appending devices to the device
97 not present at creation time.
100 Remove support for asymmetric cryptographic operations from
101 the kernel open cryptographic framework (OCF).
104 The NFSv4 client now uses the highest minor version of NFSv4
105 supported by the NFSv4 server by default instead of minor version 0,
107 The "minorversion" mount option may be used to override this default.
