1.�Introduction

This document contains the release notes for FreeBSD 10.3-RELEASE. It describes recently added, changed, or deleted features of FreeBSD. It also provides some notes on upgrading from previous versions of FreeBSD.

The snapshot distribution to which these release notes apply represents a point along the 10.3-STABLE development branch between 10.2-RELEASE and the future 10.4-RELEASE. Information regarding pre-built, binary snapshot distributions along this branch can be found at https://www.FreeBSD.org/releases/ .

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 10.3-RELEASE can be found on the FreeBSD Web site.

This document describes the most user-visible new or changed features in FreeBSD since 10.2-RELEASE.

Typical release note items document recent security advisories issued after 10.2-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.

2.�Upgrading from Previous Releases of FreeBSD

[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 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, according to the instructions in /usr/src/UPDATING .

Important:

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

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

4.1.�Userland Application Changes

The ar (1) utility now supports a -D flag to prevent real mtime, uid, gid, and file mode values from being inserted. This is called deterministic mode and useful for making the resulting archives reproducible. This behavior is enabled by default, and can be disabled by specifying a -U flag.[r287326,288202] (Sponsored by The�FreeBSD�Foundation)

The camcontrol (8) fwdownload subcommand has been improved. Changes include better support of SATA drives, downloading firmaware to IBM LTO drives, -q flag to suppress information output, and opcodes subcommand to issue the REPORT SUPPORTED OPCODES service action of the SCSI MAINTENANCE IN command.[r286965]

Bugs in the inetd (8) daemon which could cause a crash when an RPC entry is defined and an IPv6 address is specified in -a flag have been fixed.[r288048]

The jail (8) utility has been updated to include a new flag, -l , which ensures a clean environment in the target jail when used. Additionally, jail (8) will run a shell within the target jail when run no commands are specified.[r286064]

The last (1) utility now supports reboot as a pseudo-user name which prints all system reboot entries ( SHUTDOWN_TIME and BOOT_TIME records). This was accidentally removed as of FreeBSD 9.0.[r286952]

A bug in the mkimg (1) utility which prevented dynamic VHD format from working with QEMU has been fixed.[r287122]

A new utility, sesutil (8) , has been added, which is used to manage ses (4) devices.[r288710] (Sponsored by Gandi.net)

Support for a -manage-gids flag has been added to nfsuserd (8) . This option can be enabled at boot time by setting an rc.conf (5) variable nfs_server_managegids to YES . [r292231]

The pkill (1) utility now supports jail (2) name in a -j option in addition to jail (2) ID.[r287269]

The resolver library has been updated to reload /etc/resolv.conf if the modification time has changed.[r292462] (Sponsored by Dell, Inc.)

The initial implementation of reroot support has been added to the reboot (8) utility, allowing the root filesystem to be mounted from a temporary source filesystem without requiring a full system reboot.[r293744] (Sponsored by The�FreeBSD�Foundation)

The timeout (1) utility has been added. This utility runs a command with a time limit and is compatible with GNU timeout . [r287392]

The watchdogd (8) daemon now supports a -x exit_timeout option to specify the timeout period in seconds to leave in effect when the program exits.[r287080]
