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
137398d1ece5cf:
14	hw.snd.version is removed.
15
16a15f7c96a276,a8089ea5aee5:
17	NVMe over Fabrics controller.  The nvmft(4) kernel module adds
18	a new frontend to the CAM target layer which exports ctl(4)
19	LUNs as NVMe namespaces to remote hosts.  The nvmfd(8) daemon
20	is responsible for accepting incoming connection requests and
21	handing off connected queue pairs to nvmft(4).
22
23a1eda74167b5,1058c12197ab:
24	NVMe over Fabrics host.  New commands added to nvmecontrol(8)
25	to establish connections to remote controllers.  Once
26	connections are established they are handed off to the nvmf(4)
27	kernel module which creates nvmeX devices and exports remote
28	namespaces as nda(4) disks.
29
3025723d66369f:
31	As a side-effect of retiring the unit.* code in sound(4), the
32	hw.snd.maxunit loader(8) tunable is also retired.
33
34eeb04a736cb9:
35	date(1) now supports nanoseconds. For example:
36	`date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and
37	`date +%N` prints "415050400".
38
396d5ce2bb6344:
40	The default value of the nfs_reserved_port_only rc.conf(5) setting has
41	changed.  The FreeBSD NFS server now requires the source port of
42	requests to be in the privileged port range (i.e., <= 1023), which
43	generally requires the client to have elevated privileges on their local
44	system.  The previous behavior can be restored by setting
45	nfs_reserved_port_only=NO in rc.conf.
46
47aea973501b19:
48	ktrace(2) will now record detailed information about capability mode
49	violations. The kdump(1) utility has been updated to display such
50	information.
51
52f32a6403d346:
53	One True Awk updated to 2nd Edition. See https://awk.dev for details
54	on the additions. Unicode and CSVs (Comma Separated Values) are now
55	supported.
56
57fe86d923f83f:
58	usbconfig(8) now reads the descriptions of the usb vendor and products
59	from usb.ids when available, similarly to what pciconf(8) does.
60
614347ef60501f:
62	The powerd(8) utility is now enabled in /etc/rc.conf by default on
63	images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files).
64	This prevents the CPU clock from running slow all the time.
65
660b49e504a32d:
67	rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset
68	to allow unmaintained jail managers like ezjail to make use of this
69	feature (simply rename jail_${jailname}_zfs_datasets in the ezjail
70	config to jail_${jailname}_zfs_dataset.
71
72e0dfe185cbca:
73	jail(8) now support zfs.dataset to add a list of ZFS datasets to a
74        jail.
75
7661174ad88e33:
77	newsyslog(8) now supports specifying a global compression method directly
78	at the beginning of the newsyslog.conf file, which will make newsyslog(8)
79	to behave like the corresponding option was passed to the newly added
80	'-c' option. For example:
81
82	<compress> none
83
84906748d208d3:
85	newsyslog(8) now accepts a new option, '-c' which overrides all historical
86	compression flags by treating their meaning as "treat the file as compressible"
87	rather than "compress the file with that specific method."
88
89	The following choices are available:
90	 * none: Do not compress, regardless of flag.
91	 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip).
92	 * bzip2, xz, zstd, gzip: apply the specified compression method.
93
94	We plan to change the default to 'none' in FreeBSD 15.0.
95
961a878807006c:
97	This commit added some statistics collection to the NFS-over-TLS
98	code in the NFS server so that sysadmins can moditor usage.
99	The statistics are available via the kern.rpc.tls.* sysctls.
100
1017c5146da1286:
102	Mountd has been modified to use strunvis(3) to decode directory
103	names in exports(5) file(s).  This allows special characters,
104	such as blanks, to be embedded in the directory name(s).
105	"vis -M" may be used to encode such directory name(s).
106
107c5359e2af5ab:
108	bhyve(8) has a new network backend, "slirp", which makes use of the
109	libslirp package to provide a userspace network stack.  This backend
110	makes it possible to access the guest network from the host without
111	requiring any extra network configuration on the host.
112
113bb830e346bd5:
114	Set the IUTF8 flag by default in tty(4).
115
116	128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling
117	in the tty(4) driver, which is enabled by setting the new IUTF8 flag
118	through stty(1). Since the default locale is UTF-8, enable IUTF8 by
119	default.
120
121ff01d71e48d4:
122	dialog(1) has been replaced by bsddialog(1)
123
12441582f28ddf7:
125	FreeBSD 15.0 will not include support for 32-bit platforms.
126	However, 64-bit systems will still be able to run older 32-bit
127	binaries.
128
129	Support for executing 32-bit binaries on 64-bit platforms via
130	COMPAT_FREEBSD32 will remain supported for at least the
131	stable/15 and stable/16 branches.
132
133	Support for compiling individual 32-bit applications via
134	`cc -m32` will also be supported for at least the stable/15
135	branch which includes suitable headers in /usr/include and
136	libraries in /usr/lib32.
137
138	Support for 32-bit platforms in ports for 15.0 and later
139	releases is also deprecated, and these future releases may not
140	include binary packages for 32-bit platforms or support for
141	building 32-bit applications from ports.
142
143	stable/14 and earlier branches will retain existing 32-bit
144	kernel and world support.  Ports will retain existing support
145	for building ports and packages for 32-bit systems on stable/14
146	and earlier branches as long as those branches are supported
147	by the ports system.  However, all 32-bit platforms are Tier-2
148	or Tier-3 and support for individual ports should be expected
149	to degrade as upstreams deprecate 32-bit platforms.
150
151	With the current support schedule, stable/14 will be EOLed 5
152	years after the release of 14.0.  The EOL of stable/14 would
153	mark the end of support for 32-bit platforms including source
154	releases, pre-built packages, and support for building
155	applications from ports.  Given an estimated release date of
156	October 2023 for 14.0, support for 32-bit platforms would end
157	in October 2028.
158
159	The project may choose to alter this approach when 15.0 is
160	released by extending some level of 32-bit support for one or
161	more platforms in 15.0 or later.  Users should use the
162	stable/14 branch to migrate off of 32-bit platforms.
