-8e0b1a1c03a3:
- The FreeBSD-base repository is now defined in /etc/pkg/FreeBSD.conf,
- disabled by default. Systems which installed with pkgbase prior to
- 15.0-RC1 (if running releng/15.0) or November 15th (if running from
- stable/main snapshots) will need to remove the definition of the
- FreeBSD-base repository from /usr/local/etc/pkg/repos/ and replace
- it with a single line "FreeBSD-base: { enabled: yes }".
-
-5000d023a446, 03da141d59ae:
- Add a "-f" option to "kadmin -l dump" which can be used to
- dump the Heimdal KDC database in a format that can be loaded
- into the MIT KDC.
- See https://wiki.freebsd.org/Kerberos/Heimdal2MIT_KDC_Migration
- for how to use "-f" to transfer/convert the KDC database.
-
-9cab9fde5eda:
- virtual_oss is imported to base. The audio/virtual_oss port will stop
- being built from FreeBSD 15.0 onwards.
-
- Regarding user-facing changes, the only practical difference is the
- installation process. Everything is provided by the base system, except
- for the following optional components, which can be installed from
- ports:
-
- * sndio backend support: audio/virtual_oss_sndio
- * bluetooth backend support: audio/virtual_oss_bluetooth
- * virtual_equalizer(8): audio/virtual_oss_equalizer
-
- Apart from that, virtual_oss should work as expected. Users of
- virtual_oss can uninstall audio/virtual_oss and instead use the base
- system version from now on.

- Replaced Heimdal 1.5.2 with MIT KRB5 (1.21.3, 1.22.0, 1.22.1).
- Heimdal 1.5.2 can still be built using the WITHOUT_MITKRB5 flag.
- Heimdal build plumbing will be removed in 16.
-
-2b74ff5fceb6:
- Introduced support for watchdog timer in Intel 6300ESB I/O controller
- hub via the i6300esbwd driver, now included in ichwd.ko.
- This driver is intended primarily for QEMU users, where it serves as
- the default and only watchdog timer for x86 virtual machines.
-
-3068d706eabe:
- Lua updated to 5.4.8, which is minor bug fixes from 5.4.7.
-
-b45a181a74c8:
- Awk updates to August 04, 2025 version, with minor bug fixes.
-
-dc5ba6b8b4f0:
- The WITHOUT_GSSAPI src.conf(5) option has been removed. The GSSAPI
- libraries are now always built unless WITHOUT_KERBEROS is set.
-
-c43cad871720:
- jemalloc 5.3.0 has landed. See contrib/jemalloc/ChangeLog
- for the long list of changes.
-
-cce64f2e6851:
- Add support for the NFSv4.2 Clone operation, which uses
- block cloning to "copy on write" files on an NFS server.
- This only works for exported ZFS file systems that have
- block cloning enabled, at this time.
-
-37b2cb5ecb0f:
- Add support to VOP_COPY_FILE_RANGE() for block cloning.
- At this time, ZFS is the only local file system that supports
- this and only if block cloning is enabled. NFSv4.2 also supports it.
- See pathconf(2) and copy_file_range(2) for more information.
-
-2ec2ba7e232d, df58e8b1506f (openzfs 2957eabbe), f61844833ee8, b1b607bd200f,
- ee95e4d02dbd:
- Add Solaris style extended attributes (called named attributes
- in NFSv4). At this time, only ZFS when the ZFS property called
- xattr=dir and NFSv4 support them. The attributes are presented
- in a directory as regular files. See named_attribute(7) for
- more information.
-
-ef2a572bf6:
- Inline IPSEC offload infrastructure and driver support for mlx5(4)
- Nvidia ConnectX-6+ network cards were added.
-
-68ba38dad3:
- amd64: handling of the %fsbase/%gsbase registers and tls base
- were reworked, making it more useful for apps that directly
- manipulate CPU context.
-
-78aaab9f1cf:
- rtld: added support for -z initfirst
-
-e36f069ecb4, c069ca085b:
- Reliability of UFS on volumes with more than 2G of inodes is
- significantly improved. The underlying issue was the invalid
- interpretation of the 32bit inode number as signed, which got
- sign-extended into ino_t.
-
-d390633cf8c:
- On modern amd64 machines (which have the LA57 CPU feature),
- FreeBSD is able to utilize more than 4TB of RAM.
-
-2bd157bc732a:
- The readdir_r(3) function is deprecated and may be removed in future
- releases. Using it in a program will result in compile-time and
- link-time warnings.
-
-9ba51cce8bbd:
- bsnmpd(1) no longer supports legacy UDP transport. Users, that have
- not updated their /etc/snmpd.config since 12.0-RELEASE or older will
- need to merge in the new configuration. In particular, the transport
- definition shall be changed from begemotSnmpdPortStatus OID to
- begemotSnmpdTransInetStatus.
-
-1349a733cf28:
- Add a driver supporting a new storage controller interface,
- Universal Flash Storage Host Controller Interface, supporting
- version 4.1 and earlier, via ufshci(4).
-
-f1f230439fa4:
- FreeBSD now implements the inotify(2) family of system calls.
-
-50e733f19b37, 171f66b0c2ca:
- These commits helped improve utilization of NFSv4.1/4.2
- delegations. The changes are only used when the NFSv4
- mount uses the "nocto" mount option and requires an
- up-to-date NFSv4.1/4.2 server with delegations enabled.
- For example: For a FreeBSD kernel build with both src
- and obj NFSv4 mounted, the total RPC count dropped from
- 5461286 to 945643, with a 20% drop in elapsed time.
-
-c3fc0db3bc50
- The default value of the sysctl variable
- net.inet.tcp.nolocaltimewait has changed from 1 to 0. This means
- that FreeBSD does not skip the TIME_WAIT state anymore for
- endpoints for which the remote address is local. The new sysctl
- variable net.inet.tcp.msl_local can be used to control the time
- these endpoints stay in the TIME_WAIT state. The sysctl variable
- net.inet.tcp.nolocaltimewait is deprecated and intended to be
- removed in FreeBSD 16.
-
-cd240957d7ba
- Making a connection to INADDR_ANY (i.e., using INADDR_ANY as an alias
- for localhost) is now disabled by default. This functionality can be
- re-enabled by setting the net.inet.ip.connect_inaddr_wild sysctl to 1.
-
-b61850c4e6f6
- The bridge(4) sysctl net.link.bridge.member_ifaddrs now defaults to 0,
- meaning that interfaces added to a bridge may not have IP addresses
- assigned. Refer to bridge(4) for more information.
-
-44e5a0150835, 9a37f1024ceb:
- A new utility sndctl(8) has been added to concentrate the various
- interfaces for viewing and manipulating audio device settings (sysctls,
- /dev/sndstat), into a single utility with a similar control-driven
- interface to that of mixer(8).
-
-93a94ce731a8:
- ps(1)'s options '-a' and '-A', when combined with any other one
- affecting the selection of processes except for '-X' and '-x', would
- have no effect, in contradiction with the rule that one process is
- listed as soon as any of the specified options selects it (inclusive
- OR), which is both mandated by POSIX and arguably a natural expectation.
- This bug has been fixed.
-
- As a practical consequence, specifying '-a'/'-A' now causes all
- processes to be listed regardless of other selection options (except for
- '-X' and '-x', which still apply). In particular, to list only
- processes from specific jails, one must not use '-a' with '-J'. Option
- '-J', contrary to its apparent initial intent, never worked as a filter
- in practice (except by accident with '-a' due to the bug), but instead
- as any other selection options (e.g., '-U', '-p', '-G', etc.) subject to
- the "inclusive OR" rule.
-
-995b690d1398:
- ps(1)'s '-U' option has been changed to select processes by their real
- user IDs instead of their effective one, in accordance with POSIX and
- the use case of wanting to list processes launched by some user, which
- is expected to be more frequent than listing processes having the rights
- of some user. This only affects the selection of processes whose real
- and effective user IDs differ. After this change, ps(1)'s '-U' flag
- behaves differently then in other BSDs but identically to that of
- Linux's procps and illumos.
-
-1aabbb25c9f9:
- ps(1)'s default list of processes now comes from matching its effective
- user ID instead of its real user ID with the effective user ID of all
- processes, in accordance with POSIX. As ps(1) itself is not installed
- setuid, this only affects processes having different real and effective
- user IDs that launch ps(1) processes.
-
-f0600c41e754-de701f9bdbe0, bc201841d139:
- mac_do(4) is now considered production-ready and its functionality has
- been considerably extended at the price of breaking credentials
- transition rules' backwards compatibility. All that could be specified
- with old rules can also be with new rules. Migrating old rules is just
- a matter of adding "uid=" in front of the target part, substituting
- commas (",") with semi-colons (";") and colons (":") with greater-than
- signs (">"). Please consult the mac_do(4) manual page for the new rules
- grammar.
-
-02d4eeabfd73:
- hw.snd.maxautovchans has been retired. The commit introduced a
- hw.snd.vchans_enable sysctl, which along with
- dev.pcm.X.{play|rec}.vchans, from now on work as tunables to only
- enable/disable vchans, as opposed to setting their number and/or
- (de-)allocating vchans. Since these sysctls do not trigger any
- (de-)allocations anymore, their effect is instantaneous, whereas before
- we could have frozen the machine (when trying to allocate new vchans)
- when setting dev.pcm.X.{play|rec}.vchans to a very large value.
-
-7e7f88001d7d:
- The definition of pf's struct pfr_tstats and struct pfr_astats has
- changed, breaking ABI compatibility for 32-bit powerpc (including
- powerpcspe) and armv7. Users of these platforms should ensure kernel
- and userspace are updated together.
-
-5dc99e9bb985, 08e638c089a, 4009a98fe80:
- The net.inet.{tcp,udp,raw}.bind_all_fibs tunables have been added.
- They modify socket behavior such that packets not originating from the
- same FIB as the socket are ignored. TCP and UDP sockets belonging to
- different FIBs may also be bound to the same address. The default
- behavior is unmodified.
-
-f87bb5967670, e51036fbf3f8:
- Support for vinum volumes has been removed.
-
-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.
-
-1111a44301da:
- Defer the January 19, 2038 date limit in UFS1 filesystems to
- February 7, 2106. This affects only UFS1 format filesystems.
- See the commit message for details.
-
-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.
-
-a15f7c96a276,66b5296f1b29:
- 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 ctld(8) daemon
- now supports NVMe controllers in addition to iSCSI targets and
- 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.
