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
137344856e3a6d and many others:
14	Add support so that nfsd(8), nfsuserd(8), mountd(8), gssd(8)
15	and rpc.tlsservd(8) can be run in an appropriately configured
16	vnet prison.  The vnet prison must be on its own file system,
17	have the "allow.nfsd" jail parameter set on it and enforce_statfs
18	cannot be set to "0".  Use of UDP and pNFS server configurations
19	are not permitted.  (ie. The nfsd command line options "-u", "-p"
20	and "-m" are not supported.)
21	See jail(8), nfsd(8) and mountd(8).

232fb4f839f3fc,d89513ed2050,3413ee88c39d,f97a19ecb985,021562c5020d,431d2a81d421:
24	sendmail has been updated to the latest upstream version (8.17.1).
25
264a30d7bb373c,d670a8f7c596,af01b4722577,4e240e55d818:
27	The growfs(7) script can now add a swap partition at the end of
28	the expansion area, and does so by default if there is no existing
29	swap.  See growfs(7).
30
3186edb11e7491:
32	llvm-objump is now always installed as objdump.
33
34616f32ea6da7:
35	mta_start_script along with othermta rc.d script has been retired.
36
37a67b925ff3e5:
38	The default mail transport agent is now dma(8) replacing sendmail.
39
4022893e584032:
41	L3 filtering on if_bridge will do surprising things which aren't
42	fail-safe, so net.link.bridge.pfil_member and
43	net.link.bridge.pfil_bridge now default to zero.
44
45f0bc4ed144fc:
46	A new DTrace provider, kinst, is introduced and documented in
47	dtrace_kinst(4).  The provider allows kernel instructions to be traced,
48	similar to the FBT (function boundary tracing) provider except that all
49	instructions may be probed instead of logical entry and return
50	instructions.  The provider is currently amd64-only.
51
520eea46fb1f83:
53	Removed telnetd.
54
55981ef32230b2,33721eb991d8:
56	These commits make the use of NFSv4.1/4.2 mounts with the "intr"
57	mount option fairly usable, although not 100% correct, so long as
58	the "nolockd" mount option is used as well.  See the mount_nfs(8)
59	manual page for more information.
60
61b875d4f5ddcb,0685c73cfe88:
62	The NFSv4.1/4.2 client and server will now generate console messages
63	if sessions are broken, suggesting that users check to ensure
64	that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients.
65
66240afd8c1fcc:
67	makefs(8) has ZFS support; it can create a ZFS pool, backed by a
68	single disk vdev, containing one or more datasets populated from
69	the staging directory.
70
7178ee8d1c4cda,f4f56ff43dbd:
72	The in-tree qat(4) driver has been replaced with Intel's QAT driver.
73	The new version provides additional interfaces to the chipset's
74	cryptographic and compression offload functionality.
75
76	This will have no visible change for most users; however, the new
77	driver does not support Atom C2000 chipsets.  To preserve support for
78	those chipsets, the old driver has been renamed to qat_c2xxx and kept
79	in the tree.  Users of qat(4) on C2000 hardware will thus need to
80	ensure that qat_c2xxx(4) is loaded instead of qat(4).
81
82da5b7e90e740,5a8fceb3bd9f,7b0a665d72c0,13ec1e3155c7,318d0db5fe8a,1ae2c59bcf21:
83	Boottrace is a new kernel-userspace interface for capturing trace
84	events during system boot and shutdown. Event annotations are
85	present in:
86
87	- The boot and shutdown paths in the kernel
88	- Some key system utilities (init(8), shutdown(8), reboot(8))
89	- rc(8) scripts (via boottrace(8))
90
91	In contrast to other existing boot-time tracing facilities like TSLOG,
92	Boottrace focuses on the ease of use and is aimed primarily at system
93	administrators.
94
95	It is available in the default GENERIC kernel and can be enabled by
96	toggling a single sysctl(8) variable.
97
98	See boottrace(4) for more details.
99
10005a1d0f5d7ac:
101	Kernel TLS offload now supports receive-side offload of TLS 1.3.
102
10319dc64451179:
104	if_stf now supports 6rd (RFC5969).
105
106c1d255d3ffdb, 3968b47cd974, bd452dcbede6:
107	Add WiFi 6 support to wpa.
108
109ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9:
110	The default bell tone is now 800Hz. It may be set with kbdcontrol
111	again. There's devd integration for people wishing to use their sound
112	cards for the beep.
113
11492b3e07229ba:
115	net.inet.tcp.nolocaltimewait enabled by default.  It prevents
116	creation of timewait entries for TCP connections that were
117	terminated locally.
118
119d410b585b6f0:
120	sh(1) is now the default shell for the root user.
121
122396851c20aeb:
123	libncursesw has been split into libtinfow and libncursesw, linker
124	scripts should make it transparent for consumers. pkg-config files
125	are also now installed to ease ports detecting the ncurses setup from
126	base.
127
128a422084abbda:
129	LLVM's MemorySanitizer can now be used in amd64 kernels.  See the
130	kmsan(9) manual page for more information.
131
13238da497a4dfc:
133	LLVM's AddressSanitizer can now be used in amd64 kernels.  See the
134	kasan(9) manual page for more information.
135
136f39dd6a97844,23f24377b1a9,628bd30ab5a4:
137	One True Awk has been updated to the latest from upstream
138	(20210727). All the FreeBSD patches, but one, have now been
139	either up streamed or discarded.  Notable changes include:
140		o Locale is no longer used for ranges
141		o Various bugs fixed
142		o Better compatibility with gawk and mawk
143
144	The one FreeBSD change, likely to be removed in FreeBSD 14, is that
145	we still allow hex numbers, prefixed with 0x, to be parsed and
146	interpreted as hex numbers while all other awks (including one
147	true awk now) interpret them as 0 in line with awk's historic
148	behavior.
149
150	A second change, less likely to be noticed, is the historic wart
151	if -Ft meaning to use hard tab characters as the field separator
152	is deprecated and will likely be removed in FreeBSD 14.
153
154ee29e6f31111:
155	Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio
156	that can be used to increase the maximum I/O size for the NFS
157	server to any power of 2 up to 1Mbyte while the nfsd(8) is not running.
158	The FreeBSD NFS client can now be set to use a 1Mbyte I/O size
159	via the vfs.maxbcachebuf tunable and the Linux NFS client
160	can also do 1Mbyte I/O.
161	kern.ipc.maxsockbuf will need to be increased.  A console
162	message will suggest a setting for it.
163
164d575e81fbcfa:
165	gconcat(8) has added support for appending devices to the device
166	not present at creation time.
167
16876681661be28:
169	Remove support for asymmetric cryptographic operations from
170	the kernel open cryptographic framework (OCF).
171
172a145cf3f73c7:
173	The NFSv4 client now uses the highest minor version of NFSv4
174	supported by the NFSv4 server by default instead of minor version 0,
175	for NFSv4 mounts.
176	The "minorversion" mount option may be used to override this default.
