13*6e242595SChristos Margiolisf57efe95cc25:
14*6e242595SChristos Margiolis	New mididump(1) utility which dumps MIDI 1.0 events in real time.
15*6e242595SChristos Margiolis
160706fa37SBaptiste Daroussinddfc6f84f242:
170706fa37SBaptiste Daroussin	Update unicode to 16.0.0 and CLDR to 45.0.0.
180706fa37SBaptiste Daroussin
19e46c4de7SBaptiste Daroussinb22be3bbb2de:
20e46c4de7SBaptiste Daroussin	Basic Cloudinit images no longer generate RSA host keys by default for
21e46c4de7SBaptiste Daroussin	SSH.
22e46c4de7SBaptiste Daroussin
23fc2efd28SColin Percival000000000000:
24fc2efd28SColin Percival	RSA host keys for SSH are deprecated and will no longer be generated
25fc2efd28SColin Percival	by default in FreeBSD 16.
26fc2efd28SColin Percival
27279734beSColin Percival0aabcd75dbc2:
28279734beSColin Percival	EC2 AMIs no longer generate RSA host keys by default for SSH.  RSA
29279734beSColin Percival	host key generation can be re-enabled by setting sshd_rsa_enable="YES"
30279734beSColin Percival	in /etc/rc.conf if it is necessary to support very old SSH clients.
31279734beSColin Percival
32116dc70cSMark Johnstona1da7dc1cdad:
33116dc70cSMark Johnston	The SO_SPLICE socket option was added.  It allows TCP connections to
34116dc70cSMark Johnston	be spliced together, enabling proxy-like functionality without the
35116dc70cSMark Johnston	need to copy data in and out of user memory.
36116dc70cSMark Johnston
3734d9de96SMark Johnstone962b37bf0ff:
3834d9de96SMark Johnston	When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not
3934d9de96SMark Johnston	used, bhyve now assumes that the boot ROM will enable PCI BAR decoding.
4034d9de96SMark Johnston	This is incompatible with some boot ROMs, particularly outdated builds
4134d9de96SMark Johnston	of edk2-bhyve.  To restore the old behavior, add
4234d9de96SMark Johnston	"pci.enable_bars='true'" to your bhyve configuration.
4334d9de96SMark Johnston
4434d9de96SMark Johnston	Note in particular that the uefi-edk2-bhyve package has been renamed
4534d9de96SMark Johnston	to edk2-bhyve.
4634d9de96SMark Johnston
4734d9de96SMark Johnston43caa2e805c2:
4834d9de96SMark Johnston	amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are
4934d9de96SMark Johnston	deprecated.  Use the top-level "bootrom" and "bootvars" options
5034d9de96SMark Johnston	instead.
5134d9de96SMark Johnston
522e98b886SBaptiste Daroussin822ca3276345:
532e98b886SBaptiste Daroussin	byacc was updated to 20240109.
542e98b886SBaptiste Daroussin
552e98b886SBaptiste Daroussin21817992b331:
562e98b886SBaptiste Daroussin	ncurses was updated to 6.5.
572e98b886SBaptiste Daroussin
58cf9c4b32SAlexander Ziaee1687d77197c0:
59cf9c4b32SAlexander Ziaee	Filesystem manual pages have been moved to section four.
60cf9c4b32SAlexander Ziaee	Please check ports you are maintaining for crossreferences.
61cf9c4b32SAlexander Ziaee
62c180fd3dSBaptiste Daroussin8aac90f18aef:
63c180fd3dSBaptiste Daroussin	new MAC/do policy and mdo(1) utility which enables a user to
64c180fd3dSBaptiste Daroussin	become another user without the requirement of setuid root.
65c180fd3dSBaptiste Daroussin
665224825aSChristos Margiolis7398d1ece5cf:
675224825aSChristos Margiolis	hw.snd.version is removed.
685224825aSChristos Margiolis
696faf6567SJohn Baldwina15f7c96a276,a8089ea5aee5:
706faf6567SJohn Baldwin	NVMe over Fabrics controller.  The nvmft(4) kernel module adds
716faf6567SJohn Baldwin	a new frontend to the CAM target layer which exports ctl(4)
726faf6567SJohn Baldwin	LUNs as NVMe namespaces to remote hosts.  The nvmfd(8) daemon
736faf6567SJohn Baldwin	is responsible for accepting incoming connection requests and
746faf6567SJohn Baldwin	handing off connected queue pairs to nvmft(4).
756faf6567SJohn Baldwin
766faf6567SJohn Baldwina1eda74167b5,1058c12197ab:
776faf6567SJohn Baldwin	NVMe over Fabrics host.  New commands added to nvmecontrol(8)
786faf6567SJohn Baldwin	to establish connections to remote controllers.  Once
796faf6567SJohn Baldwin	connections are established they are handed off to the nvmf(4)
806faf6567SJohn Baldwin	kernel module which creates nvmeX devices and exports remote
816faf6567SJohn Baldwin	namespaces as nda(4) disks.
826faf6567SJohn Baldwin
83993d1fadSChristos Margiolis25723d66369f:
8425723d66SChristos Margiolis	As a side-effect of retiring the unit.* code in sound(4), the
8525723d66SChristos Margiolis	hw.snd.maxunit loader(8) tunable is also retired.
8654d6fea9SMateusz Piotrowski
8754d6fea9SMateusz Piotrowskieeb04a736cb9:
8854d6fea9SMateusz Piotrowski	date(1) now supports nanoseconds. For example:
8954d6fea9SMateusz Piotrowski	`date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and
9054d6fea9SMateusz Piotrowski	`date +%N` prints "415050400".
9154d6fea9SMateusz Piotrowski
92ca0620b7SMark Johnston6d5ce2bb6344:
93ca0620b7SMark Johnston	The default value of the nfs_reserved_port_only rc.conf(5) setting has
94ca0620b7SMark Johnston	changed.  The FreeBSD NFS server now requires the source port of
95ca0620b7SMark Johnston	requests to be in the privileged port range (i.e., <= 1023), which
96ca0620b7SMark Johnston	generally requires the client to have elevated privileges on their local
97ca0620b7SMark Johnston	system.  The previous behavior can be restored by setting
98ca0620b7SMark Johnston	nfs_reserved_port_only=NO in rc.conf.
99ca0620b7SMark Johnston
1001ff4bc0fSJake Freelandaea973501b19:
1011ff4bc0fSJake Freeland	ktrace(2) will now record detailed information about capability mode
1021ff4bc0fSJake Freeland	violations. The kdump(1) utility has been updated to display such
1031ff4bc0fSJake Freeland	information.
104ca0620b7SMark Johnston
1055b35479eSWarner Loshf32a6403d346:
1065b35479eSWarner Losh	One True Awk updated to 2nd Edition. See https://awk.dev for details
1075b35479eSWarner Losh	on the additions. Unicode and CSVs (Comma Separated Values) are now
1085b35479eSWarner Losh	supported.
1095b35479eSWarner Losh
1105a98d9d0SBaptiste Daroussinfe86d923f83f:
1115a98d9d0SBaptiste Daroussin	usbconfig(8) now reads the descriptions of the usb vendor and products
11273157ce4SBaptiste Daroussin	from usb.ids when available, similarly to what pciconf(8) does.
1135a98d9d0SBaptiste Daroussin
11430c741c6SMike Karels4347ef60501f:
11530c741c6SMike Karels	The powerd(8) utility is now enabled in /etc/rc.conf by default on
11630c741c6SMike Karels	images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files).
11730c741c6SMike Karels	This prevents the CPU clock from running slow all the time.
11830c741c6SMike Karels
119b9a60d36SAlexander Leidinger0b49e504a32d:
120b9a60d36SAlexander Leidinger	rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset
121b9a60d36SAlexander Leidinger	to allow unmaintained jail managers like ezjail to make use of this
122b9a60d36SAlexander Leidinger	feature (simply rename jail_${jailname}_zfs_datasets in the ezjail
123b9a60d36SAlexander Leidinger	config to jail_${jailname}_zfs_dataset.
124b9a60d36SAlexander Leidinger
125b9a60d36SAlexander Leidingere0dfe185cbca:
126b9a60d36SAlexander Leidinger	jail(8) now support zfs.dataset to add a list of ZFS datasets to a
127b9a60d36SAlexander Leidinger        jail.
128b9a60d36SAlexander Leidinger
1292f036705SXin LI61174ad88e33:
1302f036705SXin LI	newsyslog(8) now supports specifying a global compression method directly
1312f036705SXin LI	at the beginning of the newsyslog.conf file, which will make newsyslog(8)
1322f036705SXin LI	to behave like the corresponding option was passed to the newly added
1332f036705SXin LI	'-c' option. For example:
1342f036705SXin LI
1352f036705SXin LI	<compress> none
1362f036705SXin LI
1372f036705SXin LI906748d208d3:
1382f036705SXin LI	newsyslog(8) now accepts a new option, '-c' which overrides all historical
1392f036705SXin LI	compression flags by treating their meaning as "treat the file as compressible"
1402f036705SXin LI	rather than "compress the file with that specific method."
1412f036705SXin LI
1422f036705SXin LI	The following choices are available:
1432f036705SXin LI	 * none: Do not compress, regardless of flag.
1442f036705SXin LI	 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip).
1452f036705SXin LI	 * bzip2, xz, zstd, gzip: apply the specified compression method.
1462f036705SXin LI
1472f036705SXin LI	We plan to change the default to 'none' in FreeBSD 15.0.
1482f036705SXin LI
149208f089dSRick Macklem1a878807006c:
150208f089dSRick Macklem	This commit added some statistics collection to the NFS-over-TLS
151208f089dSRick Macklem	code in the NFS server so that sysadmins can moditor usage.
152208f089dSRick Macklem	The statistics are available via the kern.rpc.tls.* sysctls.
153208f089dSRick Macklem
154dac33a65SRick Macklem7c5146da1286:
155dac33a65SRick Macklem	Mountd has been modified to use strunvis(3) to decode directory
156dac33a65SRick Macklem	names in exports(5) file(s).  This allows special characters,
157dac33a65SRick Macklem	such as blanks, to be embedded in the directory name(s).
158dac33a65SRick Macklem	"vis -M" may be used to encode such directory name(s).
159dac33a65SRick Macklem
16033c2bd53SMark Johnstonc5359e2af5ab:
16133c2bd53SMark Johnston	bhyve(8) has a new network backend, "slirp", which makes use of the
16233c2bd53SMark Johnston	libslirp package to provide a userspace network stack.  This backend
16333c2bd53SMark Johnston	makes it possible to access the guest network from the host without
16433c2bd53SMark Johnston	requiring any extra network configuration on the host.
16533c2bd53SMark Johnston
166b351fa9dSChristos Margiolisbb830e346bd5:
167b351fa9dSChristos Margiolis	Set the IUTF8 flag by default in tty(4).
168b351fa9dSChristos Margiolis
169b351fa9dSChristos Margiolis	128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling
170b351fa9dSChristos Margiolis	in the tty(4) driver, which is enabled by setting the new IUTF8 flag
171b351fa9dSChristos Margiolis	through stty(1). Since the default locale is UTF-8, enable IUTF8 by
172b351fa9dSChristos Margiolis	default.
173b351fa9dSChristos Margiolis
174bb63e82eSBaptiste Daroussinff01d71e48d4:
175b627b3e6SBaptiste Daroussin	dialog(1) has been replaced by bsddialog(1)
176bb63e82eSBaptiste Daroussin
177da51a121SJohn Baldwin41582f28ddf7:
178da51a121SJohn Baldwin	FreeBSD 15.0 will not include support for 32-bit platforms.
179da51a121SJohn Baldwin	However, 64-bit systems will still be able to run older 32-bit
180da51a121SJohn Baldwin	binaries.
181da51a121SJohn Baldwin
182da51a121SJohn Baldwin	Support for executing 32-bit binaries on 64-bit platforms via
183da51a121SJohn Baldwin	COMPAT_FREEBSD32 will remain supported for at least the
184da51a121SJohn Baldwin	stable/15 and stable/16 branches.
185da51a121SJohn Baldwin
186da51a121SJohn Baldwin	Support for compiling individual 32-bit applications via
187da51a121SJohn Baldwin	`cc -m32` will also be supported for at least the stable/15
188da51a121SJohn Baldwin	branch which includes suitable headers in /usr/include and
189da51a121SJohn Baldwin	libraries in /usr/lib32.
190da51a121SJohn Baldwin
191da51a121SJohn Baldwin	Support for 32-bit platforms in ports for 15.0 and later
192da51a121SJohn Baldwin	releases is also deprecated, and these future releases may not
193da51a121SJohn Baldwin	include binary packages for 32-bit platforms or support for
194da51a121SJohn Baldwin	building 32-bit applications from ports.
195da51a121SJohn Baldwin
196da51a121SJohn Baldwin	stable/14 and earlier branches will retain existing 32-bit
197da51a121SJohn Baldwin	kernel and world support.  Ports will retain existing support
198768489c7SJohn Baldwin	for building ports and packages for 32-bit systems on stable/14
199da51a121SJohn Baldwin	and earlier branches as long as those branches are supported
200da51a121SJohn Baldwin	by the ports system.  However, all 32-bit platforms are Tier-2
201da51a121SJohn Baldwin	or Tier-3 and support for individual ports should be expected
202da51a121SJohn Baldwin	to degrade as upstreams deprecate 32-bit platforms.
203da51a121SJohn Baldwin
204da51a121SJohn Baldwin	With the current support schedule, stable/14 will be EOLed 5
205da51a121SJohn Baldwin	years after the release of 14.0.  The EOL of stable/14 would
206da51a121SJohn Baldwin	mark the end of support for 32-bit platforms including source
207da51a121SJohn Baldwin	releases, pre-built packages, and support for building
208da51a121SJohn Baldwin	applications from ports.  Given an estimated release date of
209da51a121SJohn Baldwin	October 2023 for 14.0, support for 32-bit platforms would end
210da51a121SJohn Baldwin	in October 2028.
211da51a121SJohn Baldwin
212da51a121SJohn Baldwin	The project may choose to alter this approach when 15.0 is
213da51a121SJohn Baldwin	released by extending some level of 32-bit support for one or
214da51a121SJohn Baldwin	more platforms in 15.0 or later.  Users should use the
215da51a121SJohn Baldwin	stable/14 branch to migrate off of 32-bit platforms.
216
