1. Introduction

This document contains the release notes for FreeBSD 9.3-RELEASE. It describes recently added, changed, or deleted features of FreeBSD. It also provides some notes on upgrading from previous versions of FreeBSD.

This distribution of FreeBSD 9.3-RELEASE is a snapshot distribution. It can be found at http://www.FreeBSD.org/releases/ or any of its mirrors. More information on obtaining this (or other) snapshot distributions of FreeBSD can be found in the Obtaining FreeBSD appendix to the 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 9.3-RELEASE can be found on the FreeBSD Web site.

2. What's New

This section describes the most user-visible new or changed features in FreeBSD since 9.2-RELEASE.

Typical release note items document recent security advisories issued after 9.2-RELEASE, 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.

3. Upgrading from Previous Releases of FreeBSD

3.1. Upgrading Using freebsd-update(8) or a Source-Based Procedure

[amd64,i386] Binary upgrades between RELEASE versions (and snapshots of the various security branches) are supported using the freebsd-update(8) utility. The binary upgrade procedure will update unmodified userland utilities, as well as an unmodified GENERIC kernel, distributed as a part of an official FreeBSD release. The 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 using to the instructions in /usr/src/UPDATING.

Important:

Upgrading FreeBSD should only be attempted after backing up all data and configuration files.

3.2. User-Visible Incompatibilities

FreeBSD 9.0 and later have several incompatibilities in system configuration which you might want to know before upgrading your system. Please read this section and the Upgrading Section in 9.0-RELEASE Release Notes carefully before submitting a problem report and/or posting a question to the FreeBSD mailing lists.
