3This file describes new user-visible features, changes and updates relevant to
4users of binary FreeBSD releases.  Each entry should describe the change in no
5more than several sentences and should reference manual pages where an
6interested user can find more information.  Entries should wrap after 80
7columns.  Each entry should begin with one or more commit IDs on one line,
8specified as a comma separated list and/or range, followed by a colon and a
9newline.  Entries should be separated by a newline.

12
13f0bc4ed144fc:
14	A new DTrace provider, kinst, is introduced and documented in
15	dtrace_kinst(4).  The provider allows kernel instructions to be traced,
16	similar to the FBT (function boundary tracing) provider except that all
17	instructions may be probed instead of logical entry and return
18	instructions.  The provider is currently amd64-only.
19
200eea46fb1f83:
21	Removed telnetd.
22
23981ef32230b2,33721eb991d8:
24	These commits make the use of NFSv4.1/4.2 mounts with the "intr"
25	mount option fairly usable, although not 100% correct, so long as
26	the "nolockd" mount option is used as well.  See the mount_nfs(8)
27	manual page for more information.
28
29b875d4f5ddcb,0685c73cfe88:
30	The NFSv4.1/4.2 client and server will now generate console messages
31	if sessions are broken, suggesting that users check to ensure
32	that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients.
33
34240afd8c1fcc:
35	makefs(8) has ZFS support; it can create a ZFS pool, backed by a
36	single disk vdev, containing one or more datasets populated from
37	the staging directory.
38
3978ee8d1c4cda,f4f56ff43dbd:
40	The in-tree qat(4) driver has been replaced with Intel's QAT driver.
41	The new version provides additional interfaces to the chipset's
42	cryptographic and compression offload functionality.
43
44	This will have no visible change for most users; however, the new
45	driver does not support Atom C2000 chipsets.  To preserve support for
46	those chipsets, the old driver has been renamed to qat_c2xxx and kept
47	in the tree.  Users of qat(4) on C2000 hardware will thus need to
48	ensure that qat_c2xxx(4) is loaded instead of qat(4).
49
50da5b7e90e740,5a8fceb3bd9f,7b0a665d72c0,13ec1e3155c7,318d0db5fe8a,1ae2c59bcf21:
51	Boottrace is a new kernel-userspace interface for capturing trace
52	events during system boot and shutdown. Event annotations are
53	present in:
54
55	- The boot and shutdown paths in the kernel
56	- Some key system utilities (init(8), shutdown(8), reboot(8))
57	- rc(8) scripts (via boottrace(8))
58
59	In contrast to other existing boot-time tracing facilities like TSLOG,
60	Boottrace focuses on the ease of use and is aimed primarily at system
61	administrators.
62
63	It is available in the default GENERIC kernel and can be enabled by
64	toggling a single sysctl(8) variable.
65
66	See boottrace(4) for more details.
67
6805a1d0f5d7ac:
69	Kernel TLS offload now supports receive-side offload of TLS 1.3.
70
7119dc64451179:
72	if_stf now supports 6rd (RFC5969).
73
74c1d255d3ffdb, 3968b47cd974, bd452dcbede6:
75	Add WiFi 6 support to wpa.
76
77ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9:
78	The default bell tone is now 800Hz. It may be set with kbdcontrol
79	again. There's devd integration for people wishing to use their sound
80	cards for the beep.
81
8292b3e07229ba:
83	net.inet.tcp.nolocaltimewait enabled by default.  It prevents
84	creation of timewait entries for TCP connections that were
85	terminated locally.
86
87d410b585b6f0:
88	sh(1) is now the default shell for the root user.
89
90396851c20aeb:
91	libncursesw has been split into libtinfow and libncursesw, linker
92	scripts should make it transparent for consumers. pkg-config files
93	are also now installed to ease ports detecting the ncurses setup from
94	base.
95
96a422084abbda:
97	LLVM's MemorySanitizer can now be used in amd64 kernels.  See the
98	kmsan(9) manual page for more information.
99
10038da497a4dfc:
101	LLVM's AddressSanitizer can now be used in amd64 kernels.  See the
102	kasan(9) manual page for more information.
103
104f39dd6a97844,23f24377b1a9,628bd30ab5a4:
105	One True Awk has been updated to the latest from upstream
106	(20210727). All the FreeBSD patches, but one, have now been
107	either up streamed or discarded.  Notable changes include:
108		o Locale is no longer used for ranges
109		o Various bugs fixed
110		o Better compatibility with gawk and mawk
111
112	The one FreeBSD change, likely to be removed in FreeBSD 14, is that
113	we still allow hex numbers, prefixed with 0x, to be parsed and
114	interpreted as hex numbers while all other awks (including one
115	true awk now) interpret them as 0 in line with awk's historic
116	behavior.
117
118	A second change, less likely to be noticed, is the historic wart
119	if -Ft meaning to use hard tab characters as the field separator
120	is deprecated and will likely be removed in FreeBSD 14.
121
122ee29e6f31111:
123	Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio
124	that can be used to increase the maximum I/O size for the NFS
125	server to any power of 2 up to 1Mbyte while the nfsd(8) is not running.
126	The FreeBSD NFS client can now be set to use a 1Mbyte I/O size
127	via the vfs.maxbcachebuf tunable and the Linux NFS client
128	can also do 1Mbyte I/O.
129	kern.ipc.maxsockbuf will need to be increased.  A console
130	message will suggest a setting for it.
131
132d575e81fbcfa:
133	gconcat(8) has added support for appending devices to the device
134	not present at creation time.
135
13676681661be28:
137	Remove support for asymmetric cryptographic operations from
138	the kernel open cryptographic framework (OCF).
139
140a145cf3f73c7:
141	The NFSv4 client now uses the highest minor version of NFSv4
142	supported by the NFSv4 server by default instead of minor version 0,
143	for NFSv4 mounts.
144	The "minorversion" mount option may be used to override this default.
