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
13f57efe95cc25:
14	New mididump(1) utility which dumps MIDI 1.0 events in real time.
15
16ddfc6f84f242:
17	Update unicode to 16.0.0 and CLDR to 45.0.0.
18
19b22be3bbb2de:
20	Basic Cloudinit images no longer generate RSA host keys by default for
21	SSH.
22
23000000000000:
24	RSA host keys for SSH are deprecated and will no longer be generated
25	by default in FreeBSD 16.
26
270aabcd75dbc2:
28	EC2 AMIs no longer generate RSA host keys by default for SSH.  RSA
29	host key generation can be re-enabled by setting sshd_rsa_enable="YES"
30	in /etc/rc.conf if it is necessary to support very old SSH clients.
31
32a1da7dc1cdad:
33	The SO_SPLICE socket option was added.  It allows TCP connections to
34	be spliced together, enabling proxy-like functionality without the
35	need to copy data in and out of user memory.
36
37fc12c191c087:
38	grep(1) no longer follows symbolic links by default for
39	recursive searches.  This matches the documented behavior in
40	the manual page.
41
42e962b37bf0ff:
43	When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not
44	used, bhyve now assumes that the boot ROM will enable PCI BAR decoding.
45	This is incompatible with some boot ROMs, particularly outdated builds
46	of edk2-bhyve.  To restore the old behavior, add
47	"pci.enable_bars='true'" to your bhyve configuration.
48
49	Note in particular that the uefi-edk2-bhyve package has been renamed
50	to edk2-bhyve.
51
5243caa2e805c2:
53	amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are
54	deprecated.  Use the top-level "bootrom" and "bootvars" options
55	instead.
56
57822ca3276345:
58	byacc was updated to 20240109.
59
6021817992b331:
61	ncurses was updated to 6.5.
62
631687d77197c0:
64	Filesystem manual pages have been moved to section four.
65	Please check ports you are maintaining for crossreferences.
66
678aac90f18aef:
68	new MAC/do policy and mdo(1) utility which enables a user to
69	become another user without the requirement of setuid root.
70
717398d1ece5cf:
72	hw.snd.version is removed.
73
74a15f7c96a276,a8089ea5aee5:
75	NVMe over Fabrics controller.  The nvmft(4) kernel module adds
76	a new frontend to the CAM target layer which exports ctl(4)
77	LUNs as NVMe namespaces to remote hosts.  The nvmfd(8) daemon
78	is responsible for accepting incoming connection requests and
79	handing off connected queue pairs to nvmft(4).
80
81a1eda74167b5,1058c12197ab:
82	NVMe over Fabrics host.  New commands added to nvmecontrol(8)
83	to establish connections to remote controllers.  Once
84	connections are established they are handed off to the nvmf(4)
85	kernel module which creates nvmeX devices and exports remote
86	namespaces as nda(4) disks.
87
8825723d66369f:
89	As a side-effect of retiring the unit.* code in sound(4), the
90	hw.snd.maxunit loader(8) tunable is also retired.
91
92eeb04a736cb9:
93	date(1) now supports nanoseconds. For example:
94	`date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and
95	`date +%N` prints "415050400".
96
976d5ce2bb6344:
98	The default value of the nfs_reserved_port_only rc.conf(5) setting has
99	changed.  The FreeBSD NFS server now requires the source port of
100	requests to be in the privileged port range (i.e., <= 1023), which
101	generally requires the client to have elevated privileges on their local
102	system.  The previous behavior can be restored by setting
103	nfs_reserved_port_only=NO in rc.conf.
104
105aea973501b19:
106	ktrace(2) will now record detailed information about capability mode
107	violations. The kdump(1) utility has been updated to display such
108	information.
109
110f32a6403d346:
111	One True Awk updated to 2nd Edition. See https://awk.dev for details
112	on the additions. Unicode and CSVs (Comma Separated Values) are now
113	supported.
114
115fe86d923f83f:
116	usbconfig(8) now reads the descriptions of the usb vendor and products
117	from usb.ids when available, similarly to what pciconf(8) does.
118
1194347ef60501f:
120	The powerd(8) utility is now enabled in /etc/rc.conf by default on
121	images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files).
122	This prevents the CPU clock from running slow all the time.
123
1240b49e504a32d:
125	rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset
126	to allow unmaintained jail managers like ezjail to make use of this
127	feature (simply rename jail_${jailname}_zfs_datasets in the ezjail
128	config to jail_${jailname}_zfs_dataset.
129
130e0dfe185cbca:
131	jail(8) now support zfs.dataset to add a list of ZFS datasets to a
132        jail.
133
13461174ad88e33:
135	newsyslog(8) now supports specifying a global compression method directly
136	at the beginning of the newsyslog.conf file, which will make newsyslog(8)
137	to behave like the corresponding option was passed to the newly added
138	'-c' option. For example:
139
140	<compress> none
141
142906748d208d3:
143	newsyslog(8) now accepts a new option, '-c' which overrides all historical
144	compression flags by treating their meaning as "treat the file as compressible"
145	rather than "compress the file with that specific method."
146
147	The following choices are available:
148	 * none: Do not compress, regardless of flag.
149	 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip).
150	 * bzip2, xz, zstd, gzip: apply the specified compression method.
151
152	We plan to change the default to 'none' in FreeBSD 15.0.
153
1541a878807006c:
155	This commit added some statistics collection to the NFS-over-TLS
156	code in the NFS server so that sysadmins can moditor usage.
157	The statistics are available via the kern.rpc.tls.* sysctls.
158
1597c5146da1286:
160	Mountd has been modified to use strunvis(3) to decode directory
161	names in exports(5) file(s).  This allows special characters,
162	such as blanks, to be embedded in the directory name(s).
163	"vis -M" may be used to encode such directory name(s).
164
165c5359e2af5ab:
166	bhyve(8) has a new network backend, "slirp", which makes use of the
167	libslirp package to provide a userspace network stack.  This backend
168	makes it possible to access the guest network from the host without
169	requiring any extra network configuration on the host.
170
171bb830e346bd5:
172	Set the IUTF8 flag by default in tty(4).
173
174	128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling
175	in the tty(4) driver, which is enabled by setting the new IUTF8 flag
176	through stty(1). Since the default locale is UTF-8, enable IUTF8 by
177	default.
178
179ff01d71e48d4:
180	dialog(1) has been replaced by bsddialog(1)
181
18241582f28ddf7:
183	FreeBSD 15.0 will not include support for 32-bit platforms.
184	However, 64-bit systems will still be able to run older 32-bit
185	binaries.
186
187	Support for executing 32-bit binaries on 64-bit platforms via
188	COMPAT_FREEBSD32 will remain supported for at least the
189	stable/15 and stable/16 branches.
190
191	Support for compiling individual 32-bit applications via
192	`cc -m32` will also be supported for at least the stable/15
193	branch which includes suitable headers in /usr/include and
194	libraries in /usr/lib32.
195
196	Support for 32-bit platforms in ports for 15.0 and later
197	releases is also deprecated, and these future releases may not
198	include binary packages for 32-bit platforms or support for
199	building 32-bit applications from ports.
200
201	stable/14 and earlier branches will retain existing 32-bit
202	kernel and world support.  Ports will retain existing support
203	for building ports and packages for 32-bit systems on stable/14
204	and earlier branches as long as those branches are supported
205	by the ports system.  However, all 32-bit platforms are Tier-2
206	or Tier-3 and support for individual ports should be expected
207	to degrade as upstreams deprecate 32-bit platforms.
208
209	With the current support schedule, stable/14 will be EOLed 5
210	years after the release of 14.0.  The EOL of stable/14 would
211	mark the end of support for 32-bit platforms including source
212	releases, pre-built packages, and support for building
213	applications from ports.  Given an estimated release date of
214	October 2023 for 14.0, support for 32-bit platforms would end
215	in October 2028.
216
217	The project may choose to alter this approach when 15.0 is
218	released by extending some level of 32-bit support for one or
219	more platforms in 15.0 or later.  Users should use the
220	stable/14 branch to migrate off of 32-bit platforms.
