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
211111a44301da:
22	Defer the January 19, 2038 date limit in UFS1 filesystems to
23	February 7, 2106. This affects only UFS1 format filesystems.
24	See the commit message for details.
25
2607cd69e272da:
27	Add a new -a command line option to mountd(8).
28	If this command line option is specified, when
29	a line in exports(5) has the -alldirs export option,
30	the directory must be a server file system mount point.
31
320e8a36a2ab12:
33	Add a new NFS mount option called "mountport" that may be used
34	to specify the port# for the NFS server's Mount protocol.
35	This permits a NFSv3 mount to be done without running rpcbind(8).
36
37b2f7c53430c3:
38	Kernel TLS is now enabled by default in kernels including KTLS
39	support.  KTLS is included in GENERIC kernels for aarch64,
40	amd64, powerpc64, and powerpc64le.
41
42f57efe95cc25:
43	New mididump(1) utility which dumps MIDI 1.0 events in real time.
44
45ddfc6f84f242:
46	Update unicode to 16.0.0 and CLDR to 45.0.0.
47
48b22be3bbb2de:
49	Basic Cloudinit images no longer generate RSA host keys by default for
50	SSH.
51
52000000000000:
53	RSA host keys for SSH are deprecated and will no longer be generated
54	by default in FreeBSD 16.
55
560aabcd75dbc2:
57	EC2 AMIs no longer generate RSA host keys by default for SSH.  RSA
58	host key generation can be re-enabled by setting sshd_rsa_enable="YES"
59	in /etc/rc.conf if it is necessary to support very old SSH clients.
60
61a1da7dc1cdad:
62	The SO_SPLICE socket option was added.  It allows TCP connections to
63	be spliced together, enabling proxy-like functionality without the
64	need to copy data in and out of user memory.
65
66fc12c191c087:
67	grep(1) no longer follows symbolic links by default for
68	recursive searches.  This matches the documented behavior in
69	the manual page.
70
71e962b37bf0ff:
72	When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not
73	used, bhyve now assumes that the boot ROM will enable PCI BAR decoding.
74	This is incompatible with some boot ROMs, particularly outdated builds
75	of edk2-bhyve.  To restore the old behavior, add
76	"pci.enable_bars='true'" to your bhyve configuration.
77
78	Note in particular that the uefi-edk2-bhyve package has been renamed
79	to edk2-bhyve.
80
8143caa2e805c2:
82	amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are
83	deprecated.  Use the top-level "bootrom" and "bootvars" options
84	instead.
85
86822ca3276345:
87	byacc was updated to 20240109.
88
8921817992b331:
90	ncurses was updated to 6.5.
91
921687d77197c0:
93	Filesystem manual pages have been moved to section four.
94	Please check ports you are maintaining for crossreferences.
95
968aac90f18aef:
97	new MAC/do policy and mdo(1) utility which enables a user to
98	become another user without the requirement of setuid root.
99
1007398d1ece5cf:
101	hw.snd.version is removed.
102
103a15f7c96a276,a8089ea5aee5:
104	NVMe over Fabrics controller.  The nvmft(4) kernel module adds
105	a new frontend to the CAM target layer which exports ctl(4)
106	LUNs as NVMe namespaces to remote hosts.  The nvmfd(8) daemon
107	is responsible for accepting incoming connection requests and
108	handing off connected queue pairs to nvmft(4).
109
110a1eda74167b5,1058c12197ab:
111	NVMe over Fabrics host.  New commands added to nvmecontrol(8)
112	to establish connections to remote controllers.  Once
113	connections are established they are handed off to the nvmf(4)
114	kernel module which creates nvmeX devices and exports remote
115	namespaces as nda(4) disks.
116
11725723d66369f:
118	As a side-effect of retiring the unit.* code in sound(4), the
119	hw.snd.maxunit loader(8) tunable is also retired.
120
121eeb04a736cb9:
122	date(1) now supports nanoseconds. For example:
123	`date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and
124	`date +%N` prints "415050400".
125
1266d5ce2bb6344:
127	The default value of the nfs_reserved_port_only rc.conf(5) setting has
128	changed.  The FreeBSD NFS server now requires the source port of
129	requests to be in the privileged port range (i.e., <= 1023), which
130	generally requires the client to have elevated privileges on their local
131	system.  The previous behavior can be restored by setting
132	nfs_reserved_port_only=NO in rc.conf.
133
134aea973501b19:
135	ktrace(2) will now record detailed information about capability mode
136	violations. The kdump(1) utility has been updated to display such
137	information.
138
139f32a6403d346:
140	One True Awk updated to 2nd Edition. See https://awk.dev for details
141	on the additions. Unicode and CSVs (Comma Separated Values) are now
142	supported.
143
144fe86d923f83f:
145	usbconfig(8) now reads the descriptions of the usb vendor and products
146	from usb.ids when available, similarly to what pciconf(8) does.
147
1484347ef60501f:
149	The powerd(8) utility is now enabled in /etc/rc.conf by default on
150	images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files).
151	This prevents the CPU clock from running slow all the time.
152
1530b49e504a32d:
154	rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset
155	to allow unmaintained jail managers like ezjail to make use of this
156	feature (simply rename jail_${jailname}_zfs_datasets in the ezjail
157	config to jail_${jailname}_zfs_dataset.
158
159e0dfe185cbca:
160	jail(8) now support zfs.dataset to add a list of ZFS datasets to a
161        jail.
162
16361174ad88e33:
164	newsyslog(8) now supports specifying a global compression method directly
165	at the beginning of the newsyslog.conf file, which will make newsyslog(8)
166	to behave like the corresponding option was passed to the newly added
167	'-c' option. For example:
168
169	<compress> none
170
171906748d208d3:
172	newsyslog(8) now accepts a new option, '-c' which overrides all historical
173	compression flags by treating their meaning as "treat the file as compressible"
174	rather than "compress the file with that specific method."
175
176	The following choices are available:
177	 * none: Do not compress, regardless of flag.
178	 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip).
179	 * bzip2, xz, zstd, gzip: apply the specified compression method.
180
181	We plan to change the default to 'none' in FreeBSD 15.0.
182
1831a878807006c:
184	This commit added some statistics collection to the NFS-over-TLS
185	code in the NFS server so that sysadmins can moditor usage.
186	The statistics are available via the kern.rpc.tls.* sysctls.
187
1887c5146da1286:
189	Mountd has been modified to use strunvis(3) to decode directory
190	names in exports(5) file(s).  This allows special characters,
191	such as blanks, to be embedded in the directory name(s).
192	"vis -M" may be used to encode such directory name(s).
193
194c5359e2af5ab:
195	bhyve(8) has a new network backend, "slirp", which makes use of the
196	libslirp package to provide a userspace network stack.  This backend
197	makes it possible to access the guest network from the host without
198	requiring any extra network configuration on the host.
199
200bb830e346bd5:
201	Set the IUTF8 flag by default in tty(4).
202
203	128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling
204	in the tty(4) driver, which is enabled by setting the new IUTF8 flag
205	through stty(1). Since the default locale is UTF-8, enable IUTF8 by
206	default.
207
208ff01d71e48d4:
209	dialog(1) has been replaced by bsddialog(1)
210
21141582f28ddf7:
212	FreeBSD 15.0 will not include support for 32-bit platforms.
213	However, 64-bit systems will still be able to run older 32-bit
214	binaries.
215
216	Support for executing 32-bit binaries on 64-bit platforms via
217	COMPAT_FREEBSD32 will remain supported for at least the
218	stable/15 and stable/16 branches.
219
220	Support for compiling individual 32-bit applications via
221	`cc -m32` will also be supported for at least the stable/15
222	branch which includes suitable headers in /usr/include and
223	libraries in /usr/lib32.
224
225	Support for 32-bit platforms in ports for 15.0 and later
226	releases is also deprecated, and these future releases may not
227	include binary packages for 32-bit platforms or support for
228	building 32-bit applications from ports.
229
230	stable/14 and earlier branches will retain existing 32-bit
231	kernel and world support.  Ports will retain existing support
232	for building ports and packages for 32-bit systems on stable/14
233	and earlier branches as long as those branches are supported
234	by the ports system.  However, all 32-bit platforms are Tier-2
235	or Tier-3 and support for individual ports should be expected
236	to degrade as upstreams deprecate 32-bit platforms.
237
238	With the current support schedule, stable/14 will be EOLed 5
239	years after the release of 14.0.  The EOL of stable/14 would
240	mark the end of support for 32-bit platforms including source
241	releases, pre-built packages, and support for building
242	applications from ports.  Given an estimated release date of
243	October 2023 for 14.0, support for 32-bit platforms would end
244	in October 2028.
245
246	The project may choose to alter this approach when 15.0 is
247	released by extending some level of 32-bit support for one or
248	more platforms in 15.0 or later.  Users should use the
249	stable/14 branch to migrate off of 32-bit platforms.
