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
13f87bb5967670, e51036fbf3f8:
14	Support for vinum volumes has been removed.
15
168ae6247aa966, cf0ede720391d, 205659c43d87bd, 1ccbdf561f417, 4db1b113b151:
17	The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs
18	file systems has changed.  An NFS server that exports any of these file
19	systems will need its clients to unmount and remount the exports.
20
2107cd69e272da:
22	Add a new -a command line option to mountd(8).
23	If this command line option is specified, when
24	a line in exports(5) has the -alldirs export option,
25	the directory must be a server file system mount point.
26
270e8a36a2ab12:
28	Add a new NFS mount option called "mountport" that may be used
29	to specify the port# for the NFS server's Mount protocol.
30	This permits a NFSv3 mount to be done without running rpcbind(8).
31
32b2f7c53430c3:
33	Kernel TLS is now enabled by default in kernels including KTLS
34	support.  KTLS is included in GENERIC kernels for aarch64,
35	amd64, powerpc64, and powerpc64le.
36
37f57efe95cc25:
38	New mididump(1) utility which dumps MIDI 1.0 events in real time.
39
40ddfc6f84f242:
41	Update unicode to 16.0.0 and CLDR to 45.0.0.
42
43b22be3bbb2de:
44	Basic Cloudinit images no longer generate RSA host keys by default for
45	SSH.
46
47000000000000:
48	RSA host keys for SSH are deprecated and will no longer be generated
49	by default in FreeBSD 16.
50
510aabcd75dbc2:
52	EC2 AMIs no longer generate RSA host keys by default for SSH.  RSA
53	host key generation can be re-enabled by setting sshd_rsa_enable="YES"
54	in /etc/rc.conf if it is necessary to support very old SSH clients.
55
56a1da7dc1cdad:
57	The SO_SPLICE socket option was added.  It allows TCP connections to
58	be spliced together, enabling proxy-like functionality without the
59	need to copy data in and out of user memory.
60
61fc12c191c087:
62	grep(1) no longer follows symbolic links by default for
63	recursive searches.  This matches the documented behavior in
64	the manual page.
65
66e962b37bf0ff:
67	When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not
68	used, bhyve now assumes that the boot ROM will enable PCI BAR decoding.
69	This is incompatible with some boot ROMs, particularly outdated builds
70	of edk2-bhyve.  To restore the old behavior, add
71	"pci.enable_bars='true'" to your bhyve configuration.
72
73	Note in particular that the uefi-edk2-bhyve package has been renamed
74	to edk2-bhyve.
75
7643caa2e805c2:
77	amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are
78	deprecated.  Use the top-level "bootrom" and "bootvars" options
79	instead.
80
81822ca3276345:
82	byacc was updated to 20240109.
83
8421817992b331:
85	ncurses was updated to 6.5.
86
871687d77197c0:
88	Filesystem manual pages have been moved to section four.
89	Please check ports you are maintaining for crossreferences.
90
918aac90f18aef:
92	new MAC/do policy and mdo(1) utility which enables a user to
93	become another user without the requirement of setuid root.
94
957398d1ece5cf:
96	hw.snd.version is removed.
97
98a15f7c96a276,a8089ea5aee5:
99	NVMe over Fabrics controller.  The nvmft(4) kernel module adds
100	a new frontend to the CAM target layer which exports ctl(4)
101	LUNs as NVMe namespaces to remote hosts.  The nvmfd(8) daemon
102	is responsible for accepting incoming connection requests and
103	handing off connected queue pairs to nvmft(4).
104
105a1eda74167b5,1058c12197ab:
106	NVMe over Fabrics host.  New commands added to nvmecontrol(8)
107	to establish connections to remote controllers.  Once
108	connections are established they are handed off to the nvmf(4)
109	kernel module which creates nvmeX devices and exports remote
110	namespaces as nda(4) disks.
111
11225723d66369f:
113	As a side-effect of retiring the unit.* code in sound(4), the
114	hw.snd.maxunit loader(8) tunable is also retired.
115
116eeb04a736cb9:
117	date(1) now supports nanoseconds. For example:
118	`date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and
119	`date +%N` prints "415050400".
120
1216d5ce2bb6344:
122	The default value of the nfs_reserved_port_only rc.conf(5) setting has
123	changed.  The FreeBSD NFS server now requires the source port of
124	requests to be in the privileged port range (i.e., <= 1023), which
125	generally requires the client to have elevated privileges on their local
126	system.  The previous behavior can be restored by setting
127	nfs_reserved_port_only=NO in rc.conf.
128
129aea973501b19:
130	ktrace(2) will now record detailed information about capability mode
131	violations. The kdump(1) utility has been updated to display such
132	information.
133
134f32a6403d346:
135	One True Awk updated to 2nd Edition. See https://awk.dev for details
136	on the additions. Unicode and CSVs (Comma Separated Values) are now
137	supported.
138
139fe86d923f83f:
140	usbconfig(8) now reads the descriptions of the usb vendor and products
141	from usb.ids when available, similarly to what pciconf(8) does.
142
1434347ef60501f:
144	The powerd(8) utility is now enabled in /etc/rc.conf by default on
145	images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files).
146	This prevents the CPU clock from running slow all the time.
147
1480b49e504a32d:
149	rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset
150	to allow unmaintained jail managers like ezjail to make use of this
151	feature (simply rename jail_${jailname}_zfs_datasets in the ezjail
152	config to jail_${jailname}_zfs_dataset.
153
154e0dfe185cbca:
155	jail(8) now support zfs.dataset to add a list of ZFS datasets to a
156        jail.
157
15861174ad88e33:
159	newsyslog(8) now supports specifying a global compression method directly
160	at the beginning of the newsyslog.conf file, which will make newsyslog(8)
161	to behave like the corresponding option was passed to the newly added
162	'-c' option. For example:
163
164	<compress> none
165
166906748d208d3:
167	newsyslog(8) now accepts a new option, '-c' which overrides all historical
168	compression flags by treating their meaning as "treat the file as compressible"
169	rather than "compress the file with that specific method."
170
171	The following choices are available:
172	 * none: Do not compress, regardless of flag.
173	 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip).
174	 * bzip2, xz, zstd, gzip: apply the specified compression method.
175
176	We plan to change the default to 'none' in FreeBSD 15.0.
177
1781a878807006c:
179	This commit added some statistics collection to the NFS-over-TLS
180	code in the NFS server so that sysadmins can moditor usage.
181	The statistics are available via the kern.rpc.tls.* sysctls.
182
1837c5146da1286:
184	Mountd has been modified to use strunvis(3) to decode directory
185	names in exports(5) file(s).  This allows special characters,
186	such as blanks, to be embedded in the directory name(s).
187	"vis -M" may be used to encode such directory name(s).
188
189c5359e2af5ab:
190	bhyve(8) has a new network backend, "slirp", which makes use of the
191	libslirp package to provide a userspace network stack.  This backend
192	makes it possible to access the guest network from the host without
193	requiring any extra network configuration on the host.
194
195bb830e346bd5:
196	Set the IUTF8 flag by default in tty(4).
197
198	128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling
199	in the tty(4) driver, which is enabled by setting the new IUTF8 flag
200	through stty(1). Since the default locale is UTF-8, enable IUTF8 by
201	default.
202
203ff01d71e48d4:
204	dialog(1) has been replaced by bsddialog(1)
205
20641582f28ddf7:
207	FreeBSD 15.0 will not include support for 32-bit platforms.
208	However, 64-bit systems will still be able to run older 32-bit
209	binaries.
210
211	Support for executing 32-bit binaries on 64-bit platforms via
212	COMPAT_FREEBSD32 will remain supported for at least the
213	stable/15 and stable/16 branches.
214
215	Support for compiling individual 32-bit applications via
216	`cc -m32` will also be supported for at least the stable/15
217	branch which includes suitable headers in /usr/include and
218	libraries in /usr/lib32.
219
220	Support for 32-bit platforms in ports for 15.0 and later
221	releases is also deprecated, and these future releases may not
222	include binary packages for 32-bit platforms or support for
223	building 32-bit applications from ports.
224
225	stable/14 and earlier branches will retain existing 32-bit
226	kernel and world support.  Ports will retain existing support
227	for building ports and packages for 32-bit systems on stable/14
228	and earlier branches as long as those branches are supported
229	by the ports system.  However, all 32-bit platforms are Tier-2
230	or Tier-3 and support for individual ports should be expected
231	to degrade as upstreams deprecate 32-bit platforms.
232
233	With the current support schedule, stable/14 will be EOLed 5
234	years after the release of 14.0.  The EOL of stable/14 would
235	mark the end of support for 32-bit platforms including source
236	releases, pre-built packages, and support for building
237	applications from ports.  Given an estimated release date of
238	October 2023 for 14.0, support for 32-bit platforms would end
239	in October 2028.
240
241	The project may choose to alter this approach when 15.0 is
242	released by extending some level of 32-bit support for one or
243	more platforms in 15.0 or later.  Users should use the
244	stable/14 branch to migrate off of 32-bit platforms.
