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 mta_start_script along with othermta rc.d script has been retired.
17 The default mail transport agent is now dma(8) replacing sendmail.
20 L3 filtering on if_bridge will do surprising things which aren't
21 fail-safe, so net.link.bridge.pfil_member and
22 net.link.bridge.pfil_bridge now default to zero.
25 A new DTrace provider, kinst, is introduced and documented in
26 dtrace_kinst(4). The provider allows kernel instructions to be traced,
27 similar to the FBT (function boundary tracing) provider except that all
28 instructions may be probed instead of logical entry and return
29 instructions. The provider is currently amd64-only.

35 These commits make the use of NFSv4.1/4.2 mounts with the "intr"
36 mount option fairly usable, although not 100% correct, so long as
37 the "nolockd" mount option is used as well. See the mount_nfs(8)
38 manual page for more information.
40 b875d4f5ddcb,0685c73cfe88:
41 The NFSv4.1/4.2 client and server will now generate console messages
42 if sessions are broken, suggesting that users check to ensure
43 that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients.
46 makefs(8) has ZFS support; it can create a ZFS pool, backed by a
47 single disk vdev, containing one or more datasets populated from
48 the staging directory.
50 78ee8d1c4cda,f4f56ff43dbd:
51 The in-tree qat(4) driver has been replaced with Intel's QAT driver.
52 The new version provides additional interfaces to the chipset's
53 cryptographic and compression offload functionality.
55 This will have no visible change for most users; however, the new
56 driver does not support Atom C2000 chipsets. To preserve support for
57 those chipsets, the old driver has been renamed to qat_c2xxx and kept
58 in the tree. Users of qat(4) on C2000 hardware will thus need to
59 ensure that qat_c2xxx(4) is loaded instead of qat(4).

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

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