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.
8ae6247aa966, cf0ede720391d, 205659c43d87bd, 1ccbdf561f417, 4db1b113b151:
The layout of NFS file handles for the tarfs, tmpfs, cd9660, and ext2fs
file systems has changed. An NFS server that exports any of these file
systems will need its clients to unmount and remount the exports.
07cd69e272da:
Add a new -a command line option to mountd(8).
If this command line option is specified, when
a line in exports(5) has the -alldirs export option,
the directory must be a server file system mount point.
0e8a36a2ab12:
Add a new NFS mount option called "mountport" that may be used
to specify the port# for the NFS server's Mount protocol.
This permits a NFSv3 mount to be done without running rpcbind(8).
b2f7c53430c3:
Kernel TLS is now enabled by default in kernels including KTLS
support. KTLS is included in GENERIC kernels for aarch64,
amd64, powerpc64, and powerpc64le.
f57efe95cc25:
New mididump(1) utility which dumps MIDI 1.0 events in real time.
ddfc6f84f242:
Update unicode to 16.0.0 and CLDR to 45.0.0.
b22be3bbb2de:
Basic Cloudinit images no longer generate RSA host keys by default for
SSH.
000000000000:
RSA host keys for SSH are deprecated and will no longer be generated
by default in FreeBSD 16.
0aabcd75dbc2:
EC2 AMIs no longer generate RSA host keys by default for SSH. RSA
host key generation can be re-enabled by setting sshd_rsa_enable="YES"
in /etc/rc.conf if it is necessary to support very old SSH clients.
a1da7dc1cdad:
The SO_SPLICE socket option was added. It allows TCP connections to
be spliced together, enabling proxy-like functionality without the
need to copy data in and out of user memory.
fc12c191c087:
grep(1) no longer follows symbolic links by default for
recursive searches. This matches the documented behavior in
the manual page.
e962b37bf0ff:
When running bhyve(8) guests with a boot ROM, i.e., bhyveload(8) is not
used, bhyve now assumes that the boot ROM will enable PCI BAR decoding.
This is incompatible with some boot ROMs, particularly outdated builds
of edk2-bhyve. To restore the old behavior, add
"pci.enable_bars='true'" to your bhyve configuration.
Note in particular that the uefi-edk2-bhyve package has been renamed
to edk2-bhyve.
43caa2e805c2:
amd64 bhyve(8)'s "lpc.bootrom" and "lpc.bootvars" options are
deprecated. Use the top-level "bootrom" and "bootvars" options
instead.
822ca3276345:
byacc was updated to 20240109.
21817992b331:
ncurses was updated to 6.5.
1687d77197c0:
Filesystem manual pages have been moved to section four.
Please check ports you are maintaining for crossreferences.
8aac90f18aef:
new MAC/do policy and mdo(1) utility which enables a user to
become another user without the requirement of setuid root.
7398d1ece5cf:
hw.snd.version is removed.
a15f7c96a276,a8089ea5aee5:
NVMe over Fabrics controller. The nvmft(4) kernel module adds
a new frontend to the CAM target layer which exports ctl(4)
LUNs as NVMe namespaces to remote hosts. The nvmfd(8) daemon
is responsible for accepting incoming connection requests and
handing off connected queue pairs to nvmft(4).
a1eda74167b5,1058c12197ab:
NVMe over Fabrics host. New commands added to nvmecontrol(8)
to establish connections to remote controllers. Once
connections are established they are handed off to the nvmf(4)
kernel module which creates nvmeX devices and exports remote
namespaces as nda(4) disks.
25723d66369f:
As a side-effect of retiring the unit.* code in sound(4), the
hw.snd.maxunit loader(8) tunable is also retired.
eeb04a736cb9:
date(1) now supports nanoseconds. For example:
`date -Ins` prints "2024-04-22T12:20:28,763742224+02:00" and
`date +%N` prints "415050400".
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.
