+== 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 {releaseBranch} since {releasePrev}.
+Note that some of the changes described here are also available in FreeBSD 14.0-RELEASE.
+
+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.
+The link:{handbook}cutting-edge/#freebsdupdate-upgrade[binary upgrade procedure] 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.
+====
+
+[IMPORTANT]
+====
+After installing the new userland software, running daemons are still from the previous version.
+After installing the user-level components with the second invocation of freebsd-update, or via an upgrade from source with `installworld`, the system should be rebooted to start everything with the new software.
+For example, older versions of `sshd` failed to process incoming connections correctly after the new [.filename]#/usr/sbin/sshd# was installed; rebooting started a new `sshd` and other daemons.
