  <title>What's New</title>

  <para>This section describes
<![ %include.historic; [
      the most user-visible new or changed features in &os;
      since &release.prev;.
      In general, changes described here are unique to the &release.branch;
      branch unless specifically marked as &merged; features.
]]>
<![ %no.include.historic; [
      many of the user-visible new or changed features in &os;
      since &release.prev;.  It includes items that are unique to the
      &release.branch; branch, as well as some features that may have been
      recently merged to
      other branches (after &os; &release.prev.historic;).  The later
      items are marked as &merged;.

  </para>

  <para>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.</para>

  <para>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.</para>

  <sect2 id="security">
    <title>Security Advisories</title>

    <para>A remotely exploitable vulnerability in
      <application>CVS</application> has been corrected with the
      import of version 1.11.5.  More details can be found in security
      advisory <ulink

    <title>Kernel Changes</title>

    <para arch="pc98">Support for the CanBe power management
      controller has been added. &merged;</para>

    <para>&man.devfs.5; is now mandatory; the
      <literal>NODEVFS</literal> option has been removed from the set of
      possible kernel configuration options.</para>

    <para>Linux emulation mode now supports IPv6.</para>

    <!-- Above this line, sort kernel changes by manpage/keyword-->

    <para>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
      <literal>options&nbsp;SCHED_4BSD</literal>.  The newer
      (experimental) scheduler can be selected by using
      <literal>options&nbsp;SCHED_ULE</literal>.</para>

      <title>Bootloader Changes</title>

      <para arch="alpha">The alpha boot loader
        (<filename>boot1</filename>) can now be called
        <filename>boot</filename> for consistency with other
        platforms.</para>

      <para arch="i386,pc98">The two parts of the boot loader
        (<filename>boot1</filename> and <filename>boot2</filename>)
        have been combined into a single <filename>boot</filename>
        file, to simplify programs that need to write or otherwise
        manipulate the boot loader.</para>

      <para arch="pc98">The PC98 bootloader now has support for
        booting from SCSI MO media. &merged;</para>

      <title>Network Interface Support</title>

      <para>The cm driver now supports IPX. &merged;</para>

      <para>A new wlan module provides 802.11 link-layer support.  The
	&man.wi.4; driver now uses this facility.</para>

    </sect3>

    <sect3>
      <title>Network Protocols</title>

      <para>It is now possible to build the
        <literal>FAST_IPSEC</literal> and <literal>INET6</literal>
        options into the same kernel.  (They still cannot be used
        together, however.)</para>

      <para>A bug in TCP NewReno, which caused premature exit from
	fast recovery when NewReno was enabled, has been
	fixed. &merged;</para>

    </sect3>

    <sect3>
      <title>Disks and Storage</title>

      <para>&man.geom.4; is now mandatory; the
        <literal>NO_GEOM</literal> has been removed from the set of
        kernel configuration options.</para>

      <para>Support has been added for volume labels on UFS and UFS2
        filesystems.  These labels are strings that can be used to
        identify a volume, regardless of what device it appears on.
        Labels can be set with the <option>-L</option> options to
        &man.newfs.8; or &man.tunefs.8;.  With the
        <literal>GEOM_VOL</literal> module, volumes can be accessed
        using their labels under <filename>/dev/vol</filename>.</para>

      <para>The root filesystem can now be located on a &man.vinum.4;
	volume.  More information can be found in the &man.vinum.4;
	manual page.</para>

      <para arch="pc98">The wfd and wst drivers, which have been
        broken for some time, have been removed.</para>

  <sect2 id="userland">
    <title>Userland Changes</title>

    <para arch="alpha,i386">The <filename>compat4x</filename>
      distribution now includes the
      <filename>libcrypto.so.2</filename>,
      <filename>libgmp.so.3</filename>, and
      <filename>libssl.so.2</filename> libraries from &os;
      4.7-RELEASE.

    <para>&man.config.8; now implements a <literal>nodevice</literal>
      kernel configuration file directive that cancels the effect of a
      <literal>device</literal> directive.</para>

    <para>The <option>-N</option> and <option>-W</option> flags to
      &man.disklabel.8; have been retired.</para>

    <para>&man.disklabel.8; is now only built for architectures where
      it is useful (i386, pc98, alpha, and ia64).</para>

    <para>The <option>-s</option> to &man.disklabel.8; has been
      removed because the i386 boot loader now resides in a single
      file.</para>

    <para>&man.dump.8; now supports caching of disk blocks with the
      <option>-C</option> option.  This can improve dump performance
      at the cost of possibly missing filesystem updates that occur
      between passes.</para>

    <para>&man.dumpfs.8; now supports a <option>-m</option> flag to
      print file system parameters in the form of a &man.newfs.8;
      command.</para>

    <para>&man.elfdump.1;, a utility to display information about &man.elf.5;
      format executable files, has been added.</para>

    <para>&man.fetch.1; uses the <filename>.netrc</filename> support
      in &man.fetch.3; and also supports a <option>-N</option> to
      specify an alternate <filename>.netrc</filename> file.</para>

    <para>&man.fetch.3; now has support for
      <filename>.netrc</filename> files (see &man.ftp.1; for more
      details).</para>

    <para>&man.ftpd.8; now supports a <option>-h</option> option to
      disable printing any host-specific information, such as the
      &man.ftpd.8; version or hostname, in server messages.
      &merged;</para>

    <para>&man.ftpd.8; now supports a <option>-P</option> 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. &merged;</para>

    <para>&man.ftpd.8; now supports an extended format of the
      <filename>/etc/ftpchroot</filename> file.  Please refer
      to the &man.ftpchroot.5; manpage, which is now available,
      for details. &merged;</para>

    <para>&man.ftpd.8; now supports login directory pathnames
      that specify simultaneously a directory for &man.chroot.2;
      and that to change to in the chrooted environment.  The
      <literal>/./</literal> separator is used for
      this purpose, like in other FTP daemons having this feature.
      It may be used in both &man.ftpchroot.5; and &man.passwd.5;.
      &merged;</para>

    <para>&man.fwcontrol.8; now supports <option>-R</option> and
      <option>-S</option> options for receiving and sending DV
      streams. &merged;</para>

    <para>&man.ipfw.8; now supports <literal>enable</literal> and
      <literal>disable</literal> 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;</para>

    <para>&man.kenv.1; has been moved from
      <filename>/usr/bin</filename> to <filename>/bin</filename> to
      make it available at times during system startup when only the
      root filesystem is mounted.</para>

    <para>The MAKEDEV script is now unnecessary, due to the mandatory
      presence of &man.devfs.5;, and has been removed.</para>

    <para>The &man.libgeom.3; library has been added to allow some
      userland access to the &man.geom.4; subsystem.</para>

    <para>&man.mount.nfs.8; now supports a <option>-c</option> to
      avoid doing a &man.connect.2; for UDP mount points.  This option
      must be used if the server does not reply to requests from the
      standard NFS port number 2049 or if it replies to requests using
      a different IP address (which can occur if the server is
      multi-homed).  Setting the
      <varname>vfs.nfs.nfs_ip_paranoia</varname> sysctl to
      <literal>0</literal> will make this option the
      default. &merged;</para>

    <para>&man.newsyslog.8; now supports a <literal>W</literal> flag
      to force previously-started compression jobs for an entry (or
      group of entries specified with the <literal>G</literal> 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;</para>

    <para>&man.pam.ssh.8; has been rewritten.  One side effect of the
      rewrite is that it now starts a separate instance of
      &man.ssh-agent.1; for each session instead of trying to connect
      each session to the agent started by the first session.</para>

    <para>&man.ping.8; now supports a <option>-D</option> flag to set
      the <quote>Don't Fragment</quote> bit on outgoing packets.</para>

    <para>&man.ping.8; now supports a <option>-M</option> flag to use
      ICMP mask request messages instead of ICMP echo requests.</para>

    <para>&man.ping.8; now supports a <option>-z</option> flag to set
      the Type of Service bits in outgoing packets.</para>

    <para>&man.pw.8; can now add a user whose name ends with a
      <literal>$</literal> character; this change is intended to help
      administration of <application>Samba</application>
      services. &merged;</para>

    <para arch="sparc64">The sunlabel utility, a program analogous to
      &man.disklabel.8; that works on Sun disk labels, has been
      added.</para>

    <para>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.

      <note>
        <para>The &man.swapoff.8; feature should be considered
	  experimental.</para>
      </note>
    </para>

    <para>&man.syslogd.8; now allows multiple hosts or programs to be
      named in host or program specifications in &man.syslog.conf.5;
      files.</para>

    <para>&man.systat.1; now includes an <option>-ifstat</option>
      display mode that displays the network traffic going through
      active intrfaces on the system.</para>

    <para>&man.xargs.1; now supports a <option>-P</option> option to
      execute multiple copies of the same utility in parallel.</para>

    <sect3>
      <title>Contributed Software</title>

      <para><application>OpenSSL</application> 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. &merged;</para>

      <para><application>sendmail</application> has been updated to
        version 8.12.7. &merged;</para>

      <para>&man.tcpdump.1; now supports a <option>-L</option> flag to
