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.

17 These commits make the use of NFSv4.1/4.2 mounts with the "intr"
18 mount option fairly usable, although not 100% correct, so long as
19 the "nolockd" mount option is used as well. See the mount_nfs(8)
20 manual page for more information.
22 b875d4f5ddcb,0685c73cfe88:
23 The NFSv4.1/4.2 client and server will now generate console messages
24 if sessions are broken, suggesting that users check to ensure
25 that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients.
28 makefs(8) has ZFS support; it can create a ZFS pool, backed by a
29 single disk vdev, containing one or more datasets populated from
30 the staging directory.

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

44 Boottrace is a new kernel-userspace interface for capturing trace
45 events during system boot and shutdown. Event annotations are
48 - The boot and shutdown paths in the kernel
49 - Some key system utilities (init(8), shutdown(8), reboot(8))
50 - rc(8) scripts (via boottrace(8))
52 In contrast to other existing boot-time tracing facilities like TSLOG,
53 Boottrace focuses on the ease of use and is aimed primarily at system
56 It is available in the default GENERIC kernel and can be enabled by
57 toggling a single sysctl(8) variable.
59 See boottrace(4) for more details.
62 Kernel TLS offload now supports receive-side offload of TLS 1.3.
65 if_stf now supports 6rd (RFC5969).
67 c1d255d3ffdb, 3968b47cd974, bd452dcbede6:
68 Add WiFi 6 support to wpa.
70 ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9:
71 The default bell tone is now 800Hz. It may be set with kbdcontrol
72 again. There's devd integration for people wishing to use their sound
76 net.inet.tcp.nolocaltimewait enabled by default. It prevents
77 creation of timewait entries for TCP connections that were
81 sh(1) is now the default shell for the root user.
84 libncursesw has been split into libtinfow and libncursesw, linker
85 scripts should make it transparent for consumers. pkg-config files
86 are also now installed to ease ports detecting the ncurses setup from
90 LLVM's MemorySanitizer can now be used in amd64 kernels. See the
91 kmsan(9) manual page for more information.
94 LLVM's AddressSanitizer can now be used in amd64 kernels. See the
95 kasan(9) manual page for more information.

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