== Abstract

[.abstract-title]
The release notes for FreeBSD {releaseCurrent} contain a summary of the changes made to the FreeBSD base system on the {releaseBranch} development line.
This document lists applicable security advisories that were issued since the last release, as well as significant changes to the FreeBSD kernel and userland.
Some brief remarks on upgrading are also presented.

[[intro]]
== Introduction

This document contains the release notes for FreeBSD {releaseCurrent}.
It describes recently added, changed, or deleted features of FreeBSD.
It also provides some notes on upgrading from previous versions of FreeBSD.

The {releaseType} distribution to which these release notes apply represents the latest point along the {releaseBranch} development branch since {releaseBranch} was created.
Information regarding pre-built, binary {releaseType} distributions along this branch can be found at https://www.FreeBSD.org/releases/[].

The {releaseType} distribution to which these release notes apply represents a point along the {releaseBranch} development branch between {releasePrev} and the future {releaseNext}.
Information regarding pre-built, binary {releaseType} distributions along this branch can be found at https://www.FreeBSD.org/releases/[].

This distribution of FreeBSD {releaseCurrent} is a {releaseType} distribution.
It can be found at https://www.FreeBSD.org/releases/[] or any of its mirrors.
More information on obtaining this (or other) {releaseType} distributions of FreeBSD can be found in the link:{handbook}mirrors[Obtaining FreeBSD appendix] to the link:{handbook}[FreeBSD Handbook].

All users are encouraged to consult the release errata before installing FreeBSD.
The errata document is updated with "late-breaking" information discovered late in the release cycle or after the release.
Typically, it contains information on known bugs, security advisories, and corrections to documentation.
An up-to-date copy of the errata for FreeBSD {releaseCurrent} can be found on the FreeBSD Web site.

This document describes the most user-visible new or changed features in FreeBSD since {releasePrev}.
In general, changes described here are unique to the {releaseBranch} branch unless specifically marked as MERGED features.

Typical release note items document recent security advisories issued after {releasePrev}, new drivers or hardware support, new commands or options, major bug fixes, or contributed software upgrades.
They may also list changes to major ports/packages or release engineering practices.
Clearly the release notes cannot list every single change made to FreeBSD between releases; this document focuses primarily on security advisories, user-visible changes, and major architectural improvements.

[[upgrade]]
== Upgrading from Previous Releases of FreeBSD

Binary upgrades between RELEASE versions (and snapshots of the various security branches) are supported using the man:freebsd-update[8] utility.
See the release-specific upgrade procedure, link:../installation/#upgrade-binary[FreeBSD {releaseCurrent} upgrade information], with more details in the FreeBSD handbook link:{handbook}cutting-edge/#freebsdupdate-upgrade[binary upgrade procedure].
This will update unmodified userland utilities, as well as unmodified GENERIC kernels distributed as a part of an official FreeBSD release.
The man:freebsd-update[8] utility requires that the host being upgraded have Internet connectivity.

Source-based upgrades (those based on recompiling the FreeBSD base system from source code) from previous versions are supported, according to the instructions in [.filename]#/usr/src/UPDATING#.

[IMPORTANT]
====
Upgrading FreeBSD should only be attempted after backing up _all_ data and configuration files.

[[userland]]
== Userland

This section covers changes and additions to userland applications, contributed software, and system utilities.

[[userland-config]]
=== Userland Configuration Changes

[[userland-programs]]
=== Userland Application Changes

Fix `-U` flag of man:ps[1] to select processes by real user IDs.
This is what POSIX mandates for option `-U` and arguably the behavior that most users actually need in most cases.
Before, `-U` would select processes by their effective user IDs (which is the behavior mandated by POSIX for option `-u`).
gitref:a2132d91739d[repository=src].
(Sponsored by The FreeBSD Foundation).

Make '-O' more versatile and predictable for man:ps[1].
The man:ps[1] display's list of columns is now first built without taking into account the `-O` options.
In a second step, all columns passed via `-O` are finally inserted after the built-so-far display's first PID column (if it exists, else at start), in their order of appearance as arguments to the `-O` options.
gitref:1fc8cb547cd4[repository=src].
(Sponsored by The FreeBSD Foundation).

Remove not-explicitly-requested columns with duplicate data in man:ps[1].
Before this change, when stacking up more columns in the display through command-line options, if user requested to add some "canned" display (through options `-j`, `-l`, `-u` or `-v`), columns in it that were "duplicates" of already requested ones (meaning that they share the same keyword, regardless of whether their headers have been customized) were in the end omitted.
gitref:7aa2f4826717[repository=src].
(Sponsored by The FreeBSD Foundation).

Add flags to filter jail prison and vnet variables in man:sysctl[8] output.
So users do not have to contact the source code to tell whether a variable is a jail prison / vnet one or not.
gitref:615c9ce250ee[repository=src].

man:grep[1] no longer follows symbolic links by default for recursive searches.
This matches the documented behavior in the manual page.
gitref:3a2ec5957ea9[repository=src]

[[userland-contrib]]
=== Contributed Software

llvm, clang, compiler-rt, libc++, libunwind, lld, lldb and openmp have been updated to llvm-project llvmorg-19.1.7-0-gcd708029e0b2(gitref:dc3f24ea8a25[repository=src]).

man:zfs[8]: OpenZFS has been updated to zfs-2.2-release(2.2.7)(gitref:2ec8b6948070[repository=src]).

man:xz[1] has been updated to 5.8.1(gitref:9679eedea94c[repository=src]).

man:less[1] has been updated to v668(gitref:0bb4c188d363[repository=src]).

man:file[1] has been updated to 5.46(gitref:71c92e6b94f0[repository=src]).

man:expat[3] has been updated to 2.7.1(gitref:6f7ee9ac036e[repository=src]).

`tzdata` has been updated to 2025b(gitref:475082194ac8[repository=src]).

OpenSSH has been updated to 9.9p2(gitref:059b786b7db5[repository=src]).
(Sponsored by The FreeBSD Foundation).

OpenSSL has been updated to 3.0.16(gitref:cb29db243bd0[repository=src]).

`googletest` has been updated from 1.14.0 to 1.15.2(gitref:1d67cec52542[repository=src]).
One notable change is that GoogleTest 1.15.x now officially requires C++-14 (1.14.x required C++-11).

`spleen` has been updated to Spleen 2.1.0(gitref:26336203d32c[repository=src]).

[[userland-deprecated-programs]]
=== Deprecated Applications

Update deprecation warning to note that man:gvinum[8] is removed in 15.0(gitref:dec497a9fcbf[repository=src]).

Deprecation notice for man:syscons[4] has been added.
man:syscons[4] is not compatible with UEFI, does not support UTF-8, and is Giant-locked.
There is no specific timeline yet for removing it, but support for the Giant lock is expected to go away in one or two major release cycles.
(gitref:8c922db4f3d9[repository=src]).
(Sponsored by The FreeBSD Foundation).

OpenSSH plans to remove support for the DSA signature algorithm in early 2025.

man:publickey[5] stuffs has been deprecated.
This uses DES and it is likely that nobody uses that in 2025.
(gitref:9197c04a251b[repository=src]).

[[userland-libraries]]
=== Runtime Libraries and API

`libcxxrt` has been updated to upstream 6f2fdfebcd62(gitref:d9901a23bd2f[repository=src]).

[[kernel]]
== Kernel

This section covers changes to kernel configurations, system tuning, and system control parameters that are not otherwise categorized.

[[kernel-general]]
=== General Kernel Changes

Support legacy PCI hotplug on arm64.
gitref:355f02cddbf0[repository=src].
(Sponsored by Arm Ltd).

Define a common 'mac' node for MAC's jail parameters for man:mac[3].
To be used by man:mac_do[4].
gitref:66fb52a27279[repository=src].
(Sponsored by The FreeBSD Foundation).

New `setcred()` system call and associated MAC hooks.
This new system call allows to set all necessary credentials of a process in one go: Effective, real and saved UIDs, effective, real and saved GIDs, supplementary groups and the MAC label.
Its advantage over standard credential-setting system calls (such as `setuid()`, `seteuid()`, etc.) is that it enables MAC modules, such as man:mac_do[4], to restrict the set of credentials some process may gain in a fine-grained manner.
gitref:c1d7552dddb5[repository=src].
(Sponsored by The FreeBSD Foundation).

Support multiple users and groups as single rule's targets in man:mac_do[4].
Supporting group targets is a requirement for man:mac_do[4] to be able to enforce a limited set of valid new groups passed to `setgroups()`.
Additionally, it must be possible for this set of groups to also depend on the target UID, since users and groups are quite tied in UNIX (users are automatically placed in only the groups specified through '/etc/passwd' (primary group) and '/etc/group' (supplementary ones)).
gitref:83ffc412b2e9[repository=src].
(Sponsored by The FreeBSD Foundation).

Teach man:sysctl[8] to attach and run itself in a jail.
This allows the parent jail to retrieve or set kernel state when child does not have man:sysctl[8] installed (for example light weighted OCI containers or slim jails).
This is especially useful when manipulating jail prison or vnet sysctls.
For example, `sysctl -j foo -Ja` or `sysctl -j foo net.fibs=2`.
gitref:8d5d7e2ba3a6[repository=src].

Enable vnet man:sysctl[9] variables to be loader tunable.
In gitref:3da1cf1e88f8[repository=src], the meaning of the flag `CTLFLAG_TUN` is extended to automatically check if there is a kernel environment variable which shall initialize the `SYSCTL` during early boot.
It works for all `SYSCTL` types both statically and dynamically created ones, except for the `SYSCTLs` which belong to VNETs.
Note that the implementation has a limitation.
It behaves the same way as that of non-vnet loader tunables.
That is, after the kernel or modules being initialized, any changes (for example via `kenv`) to kernel environment variable will not affect the corresponding vnet variable of subsequently created VNETs.
To overcome it, `TUNABLE_XXX_FETCH` can be used to fetch the kernel environment variable into those vnet variables during vnet constructing.
gitref:894efae09de4[repository=src]

man:sound[4]: Allocate vchans on-demand.
Refactor `pcm_chnalloc()` and merge with parts of `vchan_setnew()` (now removed) and `dsp_open()`’s channel creation into a `new dsp_chn_alloc()` function.
The function is responsible for either using a free HW channel (if `vchans` are disabled), or allocating a new vchan.
`hw.snd.vchans_enable` (previously `hw.snd.maxautovchans`) and `dev.pcm.X.{play|rec}.vchans` now 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 it could have frozen the machine (when trying to allocate new vchans) when setting `dev.pcm.X.{play|rec}.vchans` to a very large value.
gitref:960ee8094913[repository=src].
(Sponsored by	The FreeBSD Foundation).

LinuxKPI: `linux_alloc_pages()` now honors `__GFP_NORETRY`.
This is to fix slowdowns with drm-kmod that get worse over time as physical memory become more fragmented (and probably also depending on other factors).
gitref:831e6fb0baf6[repository=src]
(Sponsored by The FreeBSD Foundation).

[[drivers]]
== Devices and Drivers

This section covers changes and additions to devices and device drivers since {releasePrev}.

[[drivers-device]]
=== Device Drivers

man:mpi3mr[4] driver version has been updated to 8.14.0.2.0(gitref:e6d4b221ba7c[repository=src]).

man:mpi3mr[4] MPI Header has been updated to Version 36.
This aligns with the latest MPI specification.
This includes updated structures, field definitions, and constants required for compatibility with updated firmware.
(gitref:60cf1576501d[repository=src]).

The man:mpi3mr[4] driver is now in GENERIC (gitref:e2b8fb2202c2[repository=src]).

man:rtw88[4]: Merge Realtek's rtw88 driver based on Linux v6.14 (gitref:8ef442451791[repository=src]).
(Sponsored by The FreeBSD Foundation).

man:rtw89[4]: Merge Realtek's rtw89 driver based on Linux v6.14 (gitref:b6e8b845aeab[repository=src]).
(Sponsored by The FreeBSD Foundation).

man:iwmbtfw[4]: Add support for 9260/9560 bluetooth adaptors (gitref:8e62ae9693bd[repository=src]).
Required firmware files are already included in to package:comms/iwmbt-firmware[] port.

man:ena[4] driver version has been updated to v2.8.1 (gitref:a1685d25601e[repository=src]).
(Sponsored by Amazon, Inc.)

man:ix[4]: Add support for 1000BASE-BX SFP modules x550(gitref:24491b4acce5[repository=src]).

man:bnxt[4]: Enable NPAR support on BCM57504 10/25GbE NICs.
(gitref:54f842ed8897[repository=src]).

man:bnxt[4]: Add 5760X (Thor2) PCI IDs support.
Add Thor2 PCI IDs.
(gitref:45e161020c2d[repository=src]).

man:bnxt[4]: Add support for 400G speed modules (gitref:32fdad17f060[repository=src]).

man:ix[4]: Add support for 1000BASE-BX SFP modules.
Add support for 1Gbit BiDi modules.
(gitref:c34817d9aef7[repository=src]).

man:igc[4]: Fix attach for I226-K and LMVP devices.
The device IDs for these were in the driver's list of PCI ids to attach to, but `igc_set_mac_type()` had never been setup to set the correct mac type for these devices.
Fix this by adding these IDs to the switch block in order for them to be recognized by the driver instead of returning an error.
This fixes the man:igc[4] attach for the I226-K LOM on the ASRock Z790 PG-ITX/TB4 motherboard, allowing it to be recognized and used.
gitref:f034ddd2fa38[repository=src].

Remove old itr sysctl handler from man:em[4].
This implementation had various bugs.  The unit conversion/scaling was wrong, and it also did not handle 82574L or man:igb[4] devices correctly.
With the new AIM code, it is expected most users will not need to manually tune this.
gitref:edf50670e215[repository=src]
(Sponsored by	BBOX.io).

Added support for Brainboxes USB-to-Serial adapters in man:uftdi[4].
(gitref:47db906375b5[repository=src])

[[drivers-removals]]
=== Deprecated and Removed Drivers

[[storage]]
== Storage

This section covers changes and additions to file systems and other storage subsystems, both local and networked.

[[storage-general]]
=== General Storage

Define a new `-a` command line option man:mountd[8].
When a file system was exported with the `-alldirs` flag, the export succeeded even if the directory path was not a server file system mount point.
gitref:ead3cd3ef628[repository=src]

Document recent file handle layout changes.
gitref:ca22082c01a7[repository=src]

Allow to pass `{NGROUPS_MAX} + 1` groups in man:mountd[8].
`NGROUPS_MAX` is just the minimum maximum of the number of allowed supplementary groups.
The actual runtime value may be greater.
Allow more groups to be specified accordingly (now that, a few commits ago, man:nmount[2] has been changed similarly).
gitref:ca9614d8f64a[repository=src]
(Sponsored by The FreeBSD Foundation).

[[boot-loader]]
== Boot Loader Changes

This section covers the boot loader, boot menu, and other boot-related changes.

man:loader.efi[8]: Favor the v3 (64-bit) entry point in man:smbios[4].
Be consistent with what is done with non-EFI boot (but with the difference that EFI runs in 64-bit mode on 64-bit platforms, so there is no restriction that the v3 entry point should be below 4GB).
gitref:807d51be8040[repository=src].
(Sponsored by The FreeBSD Foundation).

man:libsa[3]: Favor the v3 (64-bit) entry point on non-EFI boot in man:smbios[4].
When both the 32-bit and 64-bit entry points are present, the SMBIOS specification says that the 64-bit entry point always has at least all the structures the 32-bit entry point refers.
In other words, the 32-bit entry point is provided for compatibility, so it is assumed the 64-bit one has more chances to be filled with adequate values.
gitref:93af0db0d529[repository=src]
(Sponsored by The FreeBSD Foundation).

man:libsa[3]: Use 64-bit entry point if table below 4GB on non-EFI boot in man:smbios[4].
On amd64, boot blocks and the non-EFI loader are 32-bit compiled as clients of BTX, so cannot access addresses beyond 4GB.
However, the 64-bit entry point may refer to a structure table below 4GB, which can be used if the BIOS does not provide a 32-bit entry point.
The situation is similar for powerpc64.
gitref:7b0350b376c0[repository=src].
(Sponsored by The FreeBSD Foundation).

Search for v3 (64-bit) entry point first on BIOS boot in man:smbios[4].
When booted from BIOS (i.e., not EFI), also search for a 64-bit version of the SMBIOS Entry Point.
This allows to detect and report the proper SMBIOS version with BIOSes that only provide the v3 table, as happens on Hetzner virtual machines.
For machines that provide both, leverage the v3 table in priority consistently with the EFI case.
gitref:145ef4af15f0[repository=src].
(Sponsored by The FreeBSD Foundation).

[[network]]
== Networking

This section describes changes that affect networking in FreeBSD.

[[network-general]]
=== General Network

Teach man:ip6addrctl[8] to attach and run itself in a jail.
This will make it easier to manage address selection policies of vnet jails, especially for those light weighted OCI containers or slim jails.
gitref:b709f7b38cc4[repository=src]

Convert `PF_DEFAULT_TO_DROP` into a vnet loader tunable 'net.pf.default_to_drop' for man:pf[4].
gitref:7f7ef494f11d[repository=src] introduced a compile time option `PF_DEFAULT_TO_DROP` to make the man:pf[4] default rule to drop.
While this change exposes a vnet loader tunable 'net.pf.default_to_drop' so that users can change the default rule without re-compiling the man:pf[4] module.
gitref:3965be101c43[repository=src]

[[wireless-networking]]
=== Wireless Networking

The LinuxKPI, particularly for 802.11, has been enhanced to support crypto offload and 802.11n and 802.11ac standards.
The man:iwlwifi[4] wireless driver is the first to make use of these new features supporting 802.11ac for some Intel Wi-Fi 5, and all of Intel Wi-Fi 6 and Wi-Fi 7 hardware. (Sponsored by The FreeBSD Foundation)

The man:rtw88[4] driver was made to work (associate) again and a memory leak got resolved. (Sponsored by The FreeBSD Foundation)

Following other drivers man:iwlwififw[4] firmware was removed from the base system in favor of the ports based solution and man:fwget[8] support. (Sponsored by The FreeBSD Foundation)

[[hardware]]
== Hardware Support

This section covers general hardware support for physical machines, hypervisors, and virtualization environments, as well as hardware changes and updates that do not otherwise fit in other sections of this document.

Please see link:https://www.freebsd.org/releases/{localRel}R/hardware[the list of hardware] supported by {releaseCurrent}, as well as link:https://www.freebsd.org/platforms/[the platforms page] for the complete list of supported CPU architectures.

[[hardware-virtualization]]
=== Virtualization Support

Several bug fixes and configuration changes collectively allow device hotplug on both x86 and arm64 ("Graviton") EC2 instances.
Users upgrading EC2 instances from earlier FreeBSD releases should set `hw.pci.intx_reroute=0` and `debug.acpi.quirks="56"` in `/boot/loader.conf`.

[[documentation]]
== Documentation

This section covers changes to manual (man:man[1]) pages and other documentation shipped with the base system.

[[man-pages]]
=== Man Pages

Refer to man:graid[8] and man:zfs[8] instead of man:gvinum[8] in man:ccdconfig[8]).
(gitref:55cb3a33d920[repository=src]).

man:ps[1]: Document change in behavior for `-a`/`-A`.
Document the practical consequence of change gitref:93a94ce731a8[repository=src] that specifying `-a`/`-A` leads to printing all processes regardless of the presence of other process selection options (except for `-x`/`-X`, which command a filter).
gitref:eed005b57895[repository=src].
(Sponsored by The FreeBSD Foundation).

man:ps[1]: Change in behavior for option `-U`.
gitref:4e4739dd0745[repository=src]
(Sponsored by The FreeBSD Foundation).

man:ps[1]: Change of how current user's processes are matched.
gitref:7219648f60d1[repository=src].
(Sponsored by The FreeBSD Foundation).

man:ps[1]: Match current user's processes using effective UID.
This puts man:ps[1] of FreeBSD in conformance with POSIX.
gitref:1e8dc267ca91[repository=src].
(Sponsored by The FreeBSD Foundation).

man:mac_do[4]: Change of rules syntax; Provide hints and pointers.
gitref:0c3357dfa18f[repository=src].
(Sponsored by The FreeBSD Foundation).

man:firewire[4]: Add deprecation notice.
This was originally discussed as part of FreeBSD 15 planning, but did not happen in time.
Add the deprecation notice now, with an expectation that it will be removed before FreeBSD 16.
gitref:fc889167c319[repository=src].
(Sponsored by The FreeBSD Foundation).

The ethernet switch controllers, man:mtkswitch[4], man:ip17x[4], man:ar40xx[4], and man:e6000sw[4] have gained initial manual pages.

man:mount[8] has gained an example for remounting all filesystems read/write in single-user mode.

Manual pages for the lua man:loader[8] modules have had their desctiptions reworded to optimize man:apropos[1] results.

The manual pages style guide, man:style.mdoc[5], has gained a section for listing supported hardware.
When listed this way, the supported hardware will be listed in link:https://www.freebsd.org/releases/{localRel}R/hardware[the supported hardware notes].
Many manuals have had this section added or reworded in this release.

Much work has gone into adding man:sysctl[8]s and environment variables to the manual.
Try searching for them with `apropos Va=here.is.the.sysctl` or `apropos Ev=here_is_the_environment_variable`.

The man:intro[5] to the File Formats manual has been revised, incorporating improvements from OpenBSD.
[[ports]]
== Ports Collection and Package Infrastructure

This section covers changes to the FreeBSD Ports Collection, package infrastructure, and package maintenance and installation tools.

A new `FreeBSD-kmods` repository is included in the default `/etc/pkg/FreeBSD.conf` man:pkg[8] configuration file.
This repository contains kernel modules compiled specifically for {releaseCurrent} rather than for the {releaseBranch} branch.
Installing kernel modules from this repository allows drivers with unstable kernel interfaces, in particular graphics drivers, to work even when the main {releaseBranch} repository has packages build on a previous release. (gitref:a47542f71511[repository=src]).

[[ports-packages]]
=== Packaging Changes

[[future-releases]]
== General Notes Regarding Future FreeBSD Releases
FreeBSD 15.0 is not expected to include support for 32-bit platforms other than armv7.
The armv6, i386, and powerpc platforms are deprecated and will be removed.
64-bit systems will still be able to run older 32-bit binaries.

The FreeBSD Project expects to support armv7 as a Tier 2 architecture in FreeBSD 15.0 and stable/15.
However, the Project also anticipates that armv7 may be removed in FreeBSD 16.0.
The Project will provide an update on the status of armv7 for both 15.x and 16.x at the time of 15.0 release.

Support for executing 32-bit binaries on 64-bit platforms via the `COMPAT_FREEBSD32` option will continue for at least the stable/15 and stable/16 branches.
Support for compiling individual 32-bit applications via `cc -m32` will also continue for at least the stable/15 branch, which includes suitable headers in [.filename]#/usr/include# and libraries in [.filename]#/usr/lib32#.

Ports will not include support for deprecated 32-bit platforms for FreeBSD 15.0 and later releases.
These future releases will not include binary packages or support for building packages from ports for deprecated 32-bit platforms.

The FreeBSD 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 reach end of life (EOL) around 5 years after the release of FreeBSD 14.0-RELEASE.
The EOL of stable/14 will mark the end of support for deprecated 32-bit platforms, including source releases, pre-built packages, and support for building applications from ports.
With the release of 14.0-RELEASE in November 2023, support for deprecated 32-bit platforms will end in November 2028.

The Project may choose to alter this approach when FreeBSD 15.0 is released by extending some level of support for one or more of the deprecated platforms in 15.0 or later.
Any alterations will be driven by community feedback and committed efforts to support these platforms.
