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.

11Changes to this file should not be MFCed.
12
13616f32ea6da7:
14	mta_start_script along with othermta rc.d script has been retired.
15
16a67b925ff3e5:
17	The default mail transport agent is now dma(8) replacing sendmail.
18
1922893e584032:
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.
23
24f0bc4ed144fc:
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.
30
310eea46fb1f83:
32	Removed telnetd.
33
34981ef32230b2,33721eb991d8:
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.
39
40b875d4f5ddcb,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.
44
45240afd8c1fcc:
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.
49
5078ee8d1c4cda,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.
54
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).
60
61da5b7e90e740,5a8fceb3bd9f,7b0a665d72c0,13ec1e3155c7,318d0db5fe8a,1ae2c59bcf21:
62	Boottrace is a new kernel-userspace interface for capturing trace
63	events during system boot and shutdown. Event annotations are
64	present in:
65
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))
69
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
72	administrators.
73
74	It is available in the default GENERIC kernel and can be enabled by
75	toggling a single sysctl(8) variable.
76
77	See boottrace(4) for more details.
78
7905a1d0f5d7ac:
80	Kernel TLS offload now supports receive-side offload of TLS 1.3.
81
8219dc64451179:
83	if_stf now supports 6rd (RFC5969).
84
85c1d255d3ffdb, 3968b47cd974, bd452dcbede6:
86	Add WiFi 6 support to wpa.
87
88ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9:
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
91	cards for the beep.
92
9392b3e07229ba:
94	net.inet.tcp.nolocaltimewait enabled by default.  It prevents
95	creation of timewait entries for TCP connections that were
96	terminated locally.
97
98d410b585b6f0:
99	sh(1) is now the default shell for the root user.
100
101396851c20aeb:
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
105	base.
106
107a422084abbda:
108	LLVM's MemorySanitizer can now be used in amd64 kernels.  See the
109	kmsan(9) manual page for more information.
110
11138da497a4dfc:
112	LLVM's AddressSanitizer can now be used in amd64 kernels.  See the
113	kasan(9) manual page for more information.
114
115f39dd6a97844,23f24377b1a9,628bd30ab5a4:
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
120		o Various bugs fixed
121		o Better compatibility with gawk and mawk
122
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
127	behavior.
128
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.
132
133ee29e6f31111:
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.
142
143d575e81fbcfa:
144	gconcat(8) has added support for appending devices to the device
145	not present at creation time.
146
14776681661be28:
148	Remove support for asymmetric cryptographic operations from
149	the kernel open cryptographic framework (OCF).
150
151a145cf3f73c7:
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,
154	for NFSv4 mounts.
155	The "minorversion" mount option may be used to override this default.
