Release notes for FreeBSD 14.0.

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.

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.

3cb2f5f369ec:
	The lua-flavored loader(8) will now interpret .lua files that appear in
	loader_conf_files as lua, and execute them in a sandbox.  Existing
	loader environment variables are available as globals in the sandbox,
	and any global variable set, if not a table value, will be reflected in
	the loader environment upon successful execution of the configuration
	file.  Environment variables with names that aren't valid lua names may
	be accessed as indices of _ENV; e.g., _ENV['net.fibs'].

bdc81eeda05d:
	nda is now the default nvme device on all platforms. While nda creates
	nvd links by default so fstab, etc continues to work, configuration
	should be updated to the new nda devices.

	To restore the old behavior, add hw.nvme.use_nvd=1 to loader.conf or
	`options NVME_USE_NVD=1` to the kernel config.  To disable the nvd
	compatibility aliases, add kern.cam.nda.nvd_compat=0 to loader.conf.

bbb2d2ce4220:
	Change pw (hence bsdinstall) not to move /home to /usr/home.
	Previously, when creating the path to home directories, pw
	would move any path in the root directory under /usr, creating
	a symlink in root.  In particular, the default /home would become
	/usr/home.  Now /home is at the top level by default.  /usr/home
	can be used explicitly.

3416e102c4e9:
	Remove TI code from armv7 GENERIC kernel.
	This code doesn't cope with newer DTS and hasn't in a long time so
	support for TI armv7 platform (like BeagleBone and Pandaboard) is now
	removed from GENERIC.

d198b8774d2c:
	Add a new "fwget" utility.
	The goal of this utility is to inspect the system for peripherals
	that needs firmware and install the appropriate packages for them.
	For now only pci subsystem is supported and only firmwares for Intel
	and AMD GPUs are known.

896516e54a8c:
	Add a new "syskrb5" mount option for Kerberized NFSv4.1/4.2 mounts.
	Without this patch, a Kerberized NFSv4.1/4.2 mount must provide
	a Kerberos credential for the client at mount time.
	This patch uses a feature of NFSv4.1/4.2 called SP4_NONE, which
	allows the state maintenance operations to be performed by any
	authentication mechanism, so that these operations may be done via
	AUTH_SYS instead of RPCSEC_GSS (KerberosV).  As such, no Kerberos
	credential is required at mount time.
	See mount_nfs(8).

330aa8acdec7,ff2f1f691cdb:
	Adds support for the SP4_MACH_CRED case for the
	NFSv4.1/4.2 ExchangeID operation since the Linux
	NFSv4.1/4.2 client is now using this for Kerberized mounts.
	This change should only affect Kerberized NFSv4.1/4.2 mounts.
	The Linux Kerberized NFSv4.1/4.2 mounts currently work without
	support for this because Linux will fall back to SP4_NONE,
	but there is no guarantee this fallback will work forever.

7344856e3a6d and many others:
	Add support so that nfsd(8), nfsuserd(8), mountd(8), gssd(8)
	and rpc.tlsservd(8) can be run in an appropriately configured
	vnet prison.  The vnet prison must be on its own file system,
	have the "allow.nfsd" jail parameter set on it and enforce_statfs
	cannot be set to "0".  Use of UDP and pNFS server configurations
	are not permitted.  (ie. The nfsd command line options "-u", "-p"
	and "-m" are not supported.)
	See jail(8), nfsd(8) and mountd(8).

2fb4f839f3fc,d89513ed2050,3413ee88c39d,f97a19ecb985,021562c5020d,431d2a81d421:
	sendmail has been updated to the latest upstream version (8.17.1).

4a30d7bb373c,d670a8f7c596,af01b4722577,4e240e55d818:
	The growfs(7) script can now add a swap partition at the end of
	the expansion area, and does so by default if there is no existing
	swap.  See growfs(7).

86edb11e7491:
	llvm-objdump is now always installed as objdump.

616f32ea6da7:
	mta_start_script along with othermta rc.d script has been retired.

a67b925ff3e5:
	The default mail transport agent is now dma(8) replacing sendmail.

22893e584032:
	L3 filtering on if_bridge will do surprising things which aren't
	fail-safe, so net.link.bridge.pfil_member and
	net.link.bridge.pfil_bridge now default to zero.

f0bc4ed144fc:
	A new DTrace provider, kinst, is introduced and documented in
	dtrace_kinst(4).  The provider allows kernel instructions to be traced,
	similar to the FBT (function boundary tracing) provider except that all
	instructions may be probed instead of logical entry and return
	instructions.  The provider is currently amd64-only.

0aa2700123e2:
	OPIE has been removed from the base system.  If you still wish
	to use it, install the security/opie port.  Otherwise, make
	sure to remove or comment out any mention of pam_opie and
	pam_opieaccess from your PAM policies (etcupdate will normally
	take care of this for the stock policies).

0eea46fb1f83:
	Removed telnetd.

981ef32230b2,33721eb991d8:
	These commits make the use of NFSv4.1/4.2 mounts with the "intr"
	mount option fairly usable, although not 100% correct, so long as
	the "nolockd" mount option is used as well.  See the mount_nfs(8)
	manual page for more information.

b875d4f5ddcb,0685c73cfe88:
	The NFSv4.1/4.2 client and server will now generate console messages
	if sessions are broken, suggesting that users check to ensure
	that the /etc/hostid strings are unique for all NFSv4.1/4.2 clients.

240afd8c1fcc:
	makefs(8) has ZFS support; it can create a ZFS pool, backed by a
	single disk vdev, containing one or more datasets populated from
	the staging directory.

78ee8d1c4cda,f4f56ff43dbd:
	The in-tree qat(4) driver has been replaced with Intel's QAT driver.
	The new version provides additional interfaces to the chipset's
	cryptographic and compression offload functionality.

	This will have no visible change for most users; however, the new
	driver does not support Atom C2000 chipsets.  To preserve support for
	those chipsets, the old driver has been renamed to qat_c2xxx and kept
	in the tree.  Users of qat(4) on C2000 hardware will thus need to
	ensure that qat_c2xxx(4) is loaded instead of qat(4).

da5b7e90e740,5a8fceb3bd9f,7b0a665d72c0,13ec1e3155c7,318d0db5fe8a,1ae2c59bcf21:
	Boottrace is a new kernel-userspace interface for capturing trace
	events during system boot and shutdown. Event annotations are
	present in:

	- The boot and shutdown paths in the kernel
	- Some key system utilities (init(8), shutdown(8), reboot(8))
	- rc(8) scripts (via boottrace(8))

	In contrast to other existing boot-time tracing facilities like TSLOG,
	Boottrace focuses on the ease of use and is aimed primarily at system
	administrators.

	It is available in the default GENERIC kernel and can be enabled by
	toggling a single sysctl(8) variable.

	See boottrace(4) for more details.

05a1d0f5d7ac:
	Kernel TLS offload now supports receive-side offload of TLS 1.3.

19dc64451179:
	if_stf now supports 6rd (RFC5969).

c1d255d3ffdb, 3968b47cd974, bd452dcbede6:
	Add WiFi 6 support to wpa.

ba48d52ca6c8,4ac3d08a9693,2533eca1c2b9:
	The default bell tone is now 800Hz. It may be set with kbdcontrol
	again. There's devd integration for people wishing to use their sound
	cards for the beep.

92b3e07229ba:
	net.inet.tcp.nolocaltimewait enabled by default.  It prevents
	creation of timewait entries for TCP connections that were
	terminated locally.

d410b585b6f0:
	sh(1) is now the default shell for the root user.

396851c20aeb:
	libncursesw has been split into libtinfow and libncursesw, linker
	scripts should make it transparent for consumers. pkg-config files
	are also now installed to ease ports detecting the ncurses setup from
	base.

a422084abbda:
	LLVM's MemorySanitizer can now be used in amd64 kernels.  See the
	kmsan(9) manual page for more information.

38da497a4dfc:
	LLVM's AddressSanitizer can now be used in amd64 kernels.  See the
	kasan(9) manual page for more information.

f39dd6a97844,23f24377b1a9,628bd30ab5a4:
	One True Awk has been updated to the latest from upstream
	(20210727). All the FreeBSD patches, but one, have now been
	either up streamed or discarded.  Notable changes include:
		o Locale is no longer used for ranges
		o Various bugs fixed
		o Better compatibility with gawk and mawk

	The one FreeBSD change, likely to be removed in FreeBSD 14, is that
	we still allow hex numbers, prefixed with 0x, to be parsed and
	interpreted as hex numbers while all other awks (including one
	true awk now) interpret them as 0 in line with awk's historic
	behavior.

	A second change, less likely to be noticed, is the historic wart
	if -Ft meaning to use hard tab characters as the field separator
	is deprecated and will likely be removed in FreeBSD 14.

ee29e6f31111:
	Commit ee29e6f31111 added a new sysctl called vfs.nfsd.srvmaxio
	that can be used to increase the maximum I/O size for the NFS
	server to any power of 2 up to 1Mbyte while the nfsd(8) is not running.
	The FreeBSD NFS client can now be set to use a 1Mbyte I/O size
	via the vfs.maxbcachebuf tunable and the Linux NFS client
	can also do 1Mbyte I/O.
	kern.ipc.maxsockbuf will need to be increased.  A console
	message will suggest a setting for it.

d575e81fbcfa:
	gconcat(8) has added support for appending devices to the device
	not present at creation time.

76681661be28:
	Remove support for asymmetric cryptographic operations from
	the kernel open cryptographic framework (OCF).

a145cf3f73c7:
	The NFSv4 client now uses the highest minor version of NFSv4
	supported by the NFSv4 server by default instead of minor version 0,
	for NFSv4 mounts.
	The "minorversion" mount option may be used to override this default.
