&os;/&arch; &release.current; Release Notes The FreeBSD Project $FreeBSD$ 2000 2001 2002 2003 The FreeBSD Documentation Project The release notes for &os; &release.current; contain a summary of Both changes for kernel and userland are listed, as well as applicable security advisories that were issued since the last release. Some brief remarks on upgrading are also presented. Introduction This document contains the release notes for &os; &release.current; on the &arch.print; hardware platform. It describes recently added, changed, or deleted features of &os;. It also provides some notes on upgrading from previous versions of &os;. The &release.type; distribution to which these release notes apply represents a point along the &release.branch; development branch between &release.prev; and the future &release.next;. Some pre-built, binary &release.type; distributions along this branch can be found at . ]]> This distribution of &os; &release.current; is a &release.type; distribution. It can be found at or any of its mirrors. More information on obtaining this (or other) &release.type; distributions of &os; can be found in the Obtaining FreeBSD appendix to the FreeBSD Handbook. ]]> What's New This section describes Typical release note items document new drivers or hardware support, new commands or options, major bugfixes, or contributed software upgrades. Applicable security advisories issued after &release.prev.historic; are also listed. Many additional changes were made to &os; that are not listed here for lack of space. For example, documentation was corrected and improved, minor bugs were fixed, insecure coding practices were audited and corrected, and source code was cleaned up. Kernel Changes &man.devfs.5; is now mandatory; the NODEVFS option has been removed from the set of possible kernel configuration options. A second process scheduler, designed to be a general purpose scheduler with many SMP benefits, has been added to the scheduler framework. Exactly one scheduler must be specified in a kernel configuration. The original scheduler may be selected using options SCHED_4BSD. The newer (experimental) scheduler can be selected by using options SCHED_ULE. Processor/Motherboard Support Bootloader Changes The alpha boot loader (boot1) can now be called boot for consistency with other platforms. The two parts of the i386 boot loader (boot1 and boot2) have been combined into a single boot file, to simplify programs that need to write or otherwise manipulate the boot loader. The PC98 bootloader now has support for booting from SCSI MO media. &merged; Network Interface Support A new module provides 802.11 link-layer support. The &man.wi.4; driver now uses this facility. Network Protocols Disks and Storage &man.geom.4; is now mandatory; the NO_GEOM has been removed from the set of kernel configuration options. Filesystems PCCARD Support Multimedia Support Contributed Software Security Advisories Userland Changes The and flags to &man.disklabel.8; have been retired. &man.disklabel.8; is now only built for architectures where it is useful (i386, pc98, alpha, and ia64). The to &man.disklabel.8; has been removed because the i386 boot loader now resides in a single file. &man.dump.8; now supports caching of disk blocks with the option. This can improve dump performance at the cost of possibly missing filesystem updates that occur between passes. &man.dumpfs.8; now supports a flag to print file system parameters in the form of a &man.newfs.8; command. elfdump, a utility to display information about &man.elf.5; format executable files, has been added. &man.fetch.1; uses the .netrc support in &man.fetch.3; and also supports a to specify an alternate .netrc file. &man.fetch.3; now has support for .netrc files (see &man.ftp.1; for more details). &man.ftpd.8; now supports a option to specify a port on which to listen in daemon mode. The default data port number is now set to be one less than the control port number, rather than being hard-coded. &man.fwcontrol.8; now supports and options for receiving and sending DV streams. &merged; &man.ipfw.8; now supports enable and disable commands to control various aspects of the operation of &man.ipfw.4; (including enabling and disabling the firewall itself). These provide a more convenient and visible interface than the existing sysctl variables. &merged; &man.kenv.1; has been moved from /usr/bin to /bin to make it available at times during system startup when only the root filesystem is mounted. &man.newsyslog.8; now supports a W flag to force previously-started compression jobs for an entry (or group of entries specified with the G flag) to finish before beginning a new one. This feature is designed to prevent system overloads caused by starting several compression jobs on big files simultaneously. &merged; &man.ping.8; now supports a flag to set the Don't Fragment bit on outgoing packets. &man.ping.8; now supports a flag to set the Type of Service bits in outgoing packets. The &man.swapoff.8; command has been added to disable paging and swapping on a device. A related &man.swapctl.8; command has been added to provide an interface to &man.swapon.8; and &man.swapoff.8; similar to other BSDs. The &man.swapoff.8; feature should be considered experimental. &man.systat.1; now includes an display mode that displays the network traffic going through active intrfaces on the system. &man.xargs.1; now supports a option to execute multiple copies of the same utility in parallel. Contributed Software awk from Bell Labs has been updated to a 13 December 2002 snapshot. BIND has been updated to version 8.3.4. &merged; All of the bzip2 suite of applications is now installed in the base system (in particular, bzip2recover is now built and installed. &merged; CVS has been updated to 1.11.5. &merged; The ISC DHCP client has been updated to 3.0.1RC11. libpcap now has support for selecting among multiple data link types on an interface. OpenPAM has been updated to the Daffodil release. OpenSSL has been updated to release 0.9.7. Among other features, this release includes support for AES and takes advantage of &man.crypto.4; devices. &man.tcpdump.1; now supports a flag to list the data link types available on an interface and a to specify the data link type to use while capturing packages. Ports/Packages Collection Infrastructure Release Engineering and Integration Documentation Upgrading from previous releases of &os; Users with existing &os; systems are highly encouraged to read the Early Adopter's Guide to &os; 5.0. This document generally has the filename EARLY.TXT on the distribution media, or any other place that the release notes can be found. It offers some notes on upgrading, but more importantly, also discusses some of the relative merits of upgrading to &os; 5.X versus running &os; 4.X. Upgrading &os; should, of course, only be attempted after backing up all data and configuration files.
