Release notes for FreeBSD 15.0.

This file describes new user-visible features, changes and updates relevant to
users of binary FreeBSD releases.  Each entry should describe the change in no
more than several sentences and should reference manual pages where an
interested user can find more information.  Entries should wrap after 80
columns.  Each entry should begin with one or more commit IDs on one line,
specified as a comma separated list and/or range, followed by a colon and a
newline.  Entries should be separated by a newline.

Changes to this file should not be MFCed.

8fef193e14e2:
	As a side-effect of retiring the unit.* code in sound(4), the
	hw.snd.maxunit loader(8) tunable is also retired.
6d5ce2bb6344:
	The default value of the nfs_reserved_port_only rc.conf(5) setting has
	changed.  The FreeBSD NFS server now requires the source port of
	requests to be in the privileged port range (i.e., <= 1023), which
	generally requires the client to have elevated privileges on their local
	system.  The previous behavior can be restored by setting
	nfs_reserved_port_only=NO in rc.conf.

aea973501b19:
	ktrace(2) will now record detailed information about capability mode
	violations. The kdump(1) utility has been updated to display such
	information.

f32a6403d346:
	One True Awk updated to 2nd Edition. See https://awk.dev for details
	on the additions. Unicode and CSVs (Comma Separated Values) are now
	supported.

fe86d923f83f:
	usbconfig(8) now reads the descriptions of the usb vendor and products
	from usb.ids when available, similarly to what pciconf(8) does.

4347ef60501f:
	The powerd(8) utility is now enabled in /etc/rc.conf by default on
	images for the arm64 Raspberry Pi's (arm64-aarch64-RPI img files).
	This prevents the CPU clock from running slow all the time.

0b49e504a32d:
	rc.d/jail now supports the legacy variable jail_${jailname}_zfs_dataset
	to allow unmaintained jail managers like ezjail to make use of this
	feature (simply rename jail_${jailname}_zfs_datasets in the ezjail
	config to jail_${jailname}_zfs_dataset.

e0dfe185cbca:
	jail(8) now support zfs.dataset to add a list of ZFS datasets to a
        jail.

61174ad88e33:
	newsyslog(8) now supports specifying a global compression method directly
	at the beginning of the newsyslog.conf file, which will make newsyslog(8)
	to behave like the corresponding option was passed to the newly added
	'-c' option. For example:

	<compress> none

906748d208d3:
	newsyslog(8) now accepts a new option, '-c' which overrides all historical
	compression flags by treating their meaning as "treat the file as compressible"
	rather than "compress the file with that specific method."

	The following choices are available:
	 * none: Do not compress, regardless of flag.
	 * legacy: Historical behavior (J=bzip2, X=xz, Y=zstd, Z=gzip).
	 * bzip2, xz, zstd, gzip: apply the specified compression method.

	We plan to change the default to 'none' in FreeBSD 15.0.

1a878807006c:
	This commit added some statistics collection to the NFS-over-TLS
	code in the NFS server so that sysadmins can moditor usage.
	The statistics are available via the kern.rpc.tls.* sysctls.

7c5146da1286:
	Mountd has been modified to use strunvis(3) to decode directory
	names in exports(5) file(s).  This allows special characters,
	such as blanks, to be embedded in the directory name(s).
	"vis -M" may be used to encode such directory name(s).

c5359e2af5ab:
	bhyve(8) has a new network backend, "slirp", which makes use of the
	libslirp package to provide a userspace network stack.  This backend
	makes it possible to access the guest network from the host without
	requiring any extra network configuration on the host.

bb830e346bd5:
	Set the IUTF8 flag by default in tty(4).

	128f63cedc14 and 9e589b093857 added proper UTF-8 backspacing handling
	in the tty(4) driver, which is enabled by setting the new IUTF8 flag
	through stty(1). Since the default locale is UTF-8, enable IUTF8 by
	default.

ff01d71e48d4:
	dialog(1) has been replaced by bsddialog(1)

41582f28ddf7:
	FreeBSD 15.0 will not include support for 32-bit platforms.
	However, 64-bit systems will still be able to run older 32-bit
	binaries.

	Support for executing 32-bit binaries on 64-bit platforms via
	COMPAT_FREEBSD32 will remain supported for at least the
	stable/15 and stable/16 branches.

	Support for compiling individual 32-bit applications via
	`cc -m32` will also be supported for at least the stable/15
	branch which includes suitable headers in /usr/include and
	libraries in /usr/lib32.

	Support for 32-bit platforms in ports for 15.0 and later
	releases is also deprecated, and these future releases may not
	include binary packages for 32-bit platforms or support for
	building 32-bit applications from ports.

	stable/14 and earlier branches will retain existing 32-bit
	kernel and world support.  Ports will retain existing support
	for building ports and packages for 32-bit systems on stable/14
	and earlier branches as long as those branches are supported
	by the ports system.  However, all 32-bit platforms are Tier-2
	or Tier-3 and support for individual ports should be expected
	to degrade as upstreams deprecate 32-bit platforms.

	With the current support schedule, stable/14 will be EOLed 5
	years after the release of 14.0.  The EOL of stable/14 would
	mark the end of support for 32-bit platforms including source
	releases, pre-built packages, and support for building
	applications from ports.  Given an estimated release date of
	October 2023 for 14.0, support for 32-bit platforms would end
	in October 2028.

	The project may choose to alter this approach when 15.0 is
	released by extending some level of 32-bit support for one or
	more platforms in 15.0 or later.  Users should use the
	stable/14 branch to migrate off of 32-bit platforms.
