== 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/[].

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.

gitref:8c6df7ead19c[repository=src] (Sponsored by The FreeBSD Foundation)

[[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.
