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
133cb2f5f369ec:
14	The lua-flavored loader(8) will now interpret .lua files that appear in
15	loader_conf_files as lua, and execute them in a sandbox.  Existing
16	loader environment variables are available as globals in the sandbox,
17	and any global variable set, if not a table value, will be reflected in
18	the loader environment upon successful execution of the configuration
19	file.  Environment variables with names that aren't valid lua names may
20	be accessed as indices of _ENV; e.g., _ENV['net.fibs'].
21
22bdc81eeda05d:
23
24	nda is now the default nvme device on all platforms. While nda creates
25	nvd links by default so fstab, etc continues to work, configuration
26	should be updated to the new nda devices.
27
28	To restore the old behavior, add hw.nvme.use_nvd=1 to loader.conf or
29	`options NVME_USE_NVD=1` to the kernel config.  To disable the nvd
30	compatibility aliases, add kern.cam.nda.nvd_compat=0 to loader.conf.
31
32bbb2d2ce4220:
33	Change pw (hence bsdinstall) not to move /home to /usr/home.
34	Previously, when creating the path to home directories, pw
35	would move any path in the root directory under /usr, creating
36	a symlink in root.  In particular, the default /home would become
37	/usr/home.  Now /home is at the top level by default.  /usr/home
38	can be used explicitly.
39
403416e102c4e9:
41	Remove TI code from armv7 GENERIC kernel.
42	This code doesn't cope with newer DTS and hasn't in a long time so
43	support for TI armv7 platform (like BeagleBone and Pandaboard) is now
44	removed from GENERIC.
45
46d198b8774d2c:
47	Add a new "fwget" utility.
48	The goal of this utility is to inspect the system for peripherals
49	that needs firmware and install the appropriate packages for them.
50	For now only pci subsystem is supported and only firmwares for Intel
51	and AMD GPUs are known.
52
53896516e54a8c:
54	Add a new "syskrb5" mount option for Kerberized NFSv4.1/4.2 mounts.
55	Without this patch, a Kerberized NFSv4.1/4.2 mount must provide
56	a Kerberos credential for the client at mount time.
57	This patch uses a feature of NFSv4.1/4.2 called SP4_NONE, which
58	allows the state maintenance operations to be performed by any
59	authentication mechanism, so that these operations may be done via
60	AUTH_SYS instead of RPCSEC_GSS (KerberosV).  As such, no Kerberos
61	credential is required at mount time.
62	See mount_nfs(8).
63
64330aa8acdec7,ff2f1f691cdb:
65	Adds support for the SP4_MACH_CRED case for the
66	NFSv4.1/4.2 ExchangeID operation since the Linux
67	NFSv4.1/4.2 client is now using this for Kerberized mounts.
68	This change should only affect Kerberized NFSv4.1/4.2 mounts.
69	The Linux Kerberized NFSv4.1/4.2 mounts currently work without
70	support for this because Linux will fall back to SP4_NONE,
71	but there is no guarantee this fallback will work forever.
72
737344856e3a6d and many others:
74	Add support so that nfsd(8), nfsuserd(8), mountd(8), gssd(8)
75	and rpc.tlsservd(8) can be run in an appropriately configured
76	vnet prison.  The vnet prison must be on its own file system,
77	have the "allow.nfsd" jail parameter set on it and enforce_statfs
78	cannot be set to "0".  Use of UDP and pNFS server configurations
79	are not permitted.  (ie. The nfsd command line options "-u", "-p"
80	and "-m" are not supported.)
81	See jail(8), nfsd(8) and mountd(8).
82
832fb4f839f3fc,d89513ed2050,3413ee88c39d,f97a19ecb985,021562c5020d,431d2a81d421:
84	sendmail has been updated to the latest upstream version (8.17.1).
85
864a30d7bb373c,d670a8f7c596,af01b4722577,4e240e55d818:
87	The growfs(7) script can now add a swap partition at the end of
88	the expansion area, and does so by default if there is no existing
89	swap.  See growfs(7).
90
9186edb11e7491:
92	llvm-objump is now always installed as objdump.
93
94616f32ea6da7:
95	mta_start_script along with othermta rc.d script has been retired.
96
97a67b925ff3e5:
98	The default mail transport agent is now dma(8) replacing sendmail.
99
10022893e584032:
101	L3 filtering on if_bridge will do surprising things which aren't
102	fail-safe, so net.link.bridge.pfil_member and
103	net.link.bridge.pfil_bridge now default to zero.
104
105f0bc4ed144fc:
106	A new DTrace provider, kinst, is introduced and documented in
107	dtrace_kinst(4).  The provider allows kernel instructions to be traced,
108	similar to the FBT (function boundary tracing) provider except that all
109	instructions may be probed instead of logical entry and return
110	instructions.  The provider is currently amd64-only.
111
1120eea46fb1f83:
113	Removed telnetd.
114
115981ef32230b2,33721eb991d8:
116	These commits make the use of NFSv4.1/4.2 mounts with the "intr"
117	mount option fairly usable, although not 100% correct, so long as
118	the "nolockd" mount option is used as well.  See the mount_nfs(8)
119	manual page for more information.
120
121b875d4f5ddcb,0685c73cfe88:
122	The NFSv4.1/4.2 client and server will now generate console messages
123	if sessions are broken, suggesting that users check to ensure
124	that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients.
125
126240afd8c1fcc:
127	makefs(8) has ZFS support; it can create a ZFS pool, backed by a
128	single disk vdev, containing one or more datasets populated from
129	the staging directory.
130
13178ee8d1c4cda,f4f56ff43dbd:
132	The in-tree qat(4) driver has been replaced with Intel's QAT driver.
133	The new version provides additional interfaces to the chipset's
134	cryptographic and compression offload functionality.
135
136	This will have no visible change for most users; however, the new
137	driver does not support Atom C2000 chipsets.  To preserve support for
138	those chipsets, the old driver has been renamed to qat_c2xxx and kept
139	in the tree.  Users of qat(4) on C2000 hardware will thus need to
140	ensure that qat_c2xxx(4) is loaded instead of qat(4).
141
142da5b7e90e740,5a8fceb3bd9f,7b0a665d72c0,13ec1e3155c7,318d0db5fe8a,1ae2c59bcf21:
143	Boottrace is a new kernel-userspace interface for capturing trace
144	events during system boot and shutdown. Event annotations are
145	present in:
146
147	- The boot and shutdown paths in the kernel
148	- Some key system utilities (init(8), shutdown(8), reboot(8))
149	- rc(8) scripts (via boottrace(8))
150
151	In contrast to other existing boot-time tracing facilities like TSLOG,
152	Boottrace focuses on the ease of use and is aimed primarily at system
153	administrators.
154
155	It is available in the default GENERIC kernel and can be enabled by
156	toggling a single sysctl(8) variable.
157
158	See boottrace(4) for more details.
159
16005a1d0f5d7ac:
161	Kernel TLS offload now supports receive-side offload of TLS 1.3.
162
16319dc64451179:
164	if_stf now supports 6rd (RFC5969).
165
166c1d255d3ffdb, 3968b47cd974, bd452dcbede6:
167	Add WiFi 6 support to wpa.
168
169ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9:
170	The default bell tone is now 800Hz. It may be set with kbdcontrol
171	again. There's devd integration for people wishing to use their sound
172	cards for the beep.
173
17492b3e07229ba:
175	net.inet.tcp.nolocaltimewait enabled by default.  It prevents
176	creation of timewait entries for TCP connections that were
177	terminated locally.
178
179d410b585b6f0:
180	sh(1) is now the default shell for the root user.
181
182396851c20aeb:
183	libncursesw has been split into libtinfow and libncursesw, linker
184	scripts should make it transparent for consumers. pkg-config files
185	are also now installed to ease ports detecting the ncurses setup from
186	base.
187
188a422084abbda:
189	LLVM's MemorySanitizer can now be used in amd64 kernels.  See the
190	kmsan(9) manual page for more information.
191
19238da497a4dfc:
193	LLVM's AddressSanitizer can now be used in amd64 kernels.  See the
194	kasan(9) manual page for more information.
195
196f39dd6a97844,23f24377b1a9,628bd30ab5a4:
197	One True Awk has been updated to the latest from upstream
198	(20210727). All the FreeBSD patches, but one, have now been
199	either up streamed or discarded.  Notable changes include:
200		o Locale is no longer used for ranges
201		o Various bugs fixed
202		o Better compatibility with gawk and mawk
203
204	The one FreeBSD change, likely to be removed in FreeBSD 14, is that
205	we still allow hex numbers, prefixed with 0x, to be parsed and
206	interpreted as hex numbers while all other awks (including one
207	true awk now) interpret them as 0 in line with awk's historic
208	behavior.
209
210	A second change, less likely to be noticed, is the historic wart
211	if -Ft meaning to use hard tab characters as the field separator
212	is deprecated and will likely be removed in FreeBSD 14.
213
214ee29e6f31111:
215	Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio
216	that can be used to increase the maximum I/O size for the NFS
217	server to any power of 2 up to 1Mbyte while the nfsd(8) is not running.
218	The FreeBSD NFS client can now be set to use a 1Mbyte I/O size
219	via the vfs.maxbcachebuf tunable and the Linux NFS client
220	can also do 1Mbyte I/O.
221	kern.ipc.maxsockbuf will need to be increased.  A console
222	message will suggest a setting for it.
223
224d575e81fbcfa:
225	gconcat(8) has added support for appending devices to the device
226	not present at creation time.
227
22876681661be28:
229	Remove support for asymmetric cryptographic operations from
230	the kernel open cryptographic framework (OCF).
231
232a145cf3f73c7:
233	The NFSv4 client now uses the highest minor version of NFSv4
234	supported by the NFSv4 server by default instead of minor version 0,
235	for NFSv4 mounts.
236	The "minorversion" mount option may be used to override this default.
