<li>Xen platform support and the <a href="https://man.openbsd.org/xbf.4">xbf(4)</a> driver in particular have been substantially improved.
<li>...
</ul>
<p>
<li>New <a href="https://man.openbsd.org/amd64/vmm.4">vmm(4)</a>/
<a href="https://man.openbsd.org/amd64/vmd.8">vmd(8)</a>:
<ul>
<li>...
</ul>
<p>
<li>IEEE 802.11 wireless stack improvements:
<ul>
<li>MiRA 802.11n TX rate scaling now supports devices with unequal numbers of Tx and Rx streams. Fixes 11n mode for some <a href="https://man.openbsd.org/athn.8">athn(8)</a> devices.
<li>The <a href="https://man.openbsd.org/iwn.8">iwn(8)</a> and <a href="https://man.openbsd.org/iwm.8">iwm(8)</a> drivers will now start scanning for a new access point if they no longer receive beacons from their current AP.
<li>Prefer the 5GHz band over the 2GHz band during access point selection.
<li>Improved debug output in <a href="https://man.openbsd.org/dmesg.8">dmesg(8)</a> when a wireless interface is put into debug mode with <a href="https://man.openbsd.org/ifconfig.8">ifconfig(8)</a>.
</ul>
<p>
<li>Generic network stack improvements:
<ul>
<li> Incoming and forwarded IP packets are now processed without
KERNEL_LOCK, resulting in better performances and reduced latency
<li> The kernel no longer handles IPv6 Stateless Address
Autoconfiguration (RFC 4862), allowing cleanup and simplification
of the IPv6 network stack.
<li> The kernel sends IPv6 router solicitations for link local addresses
with a link local source address.
<li> FQ-CoDel algorithm has been implemented for use with <a
href="https://man.openbsd.org/pf.conf#QUEUEING">pf(4) queueing</a>.
<li>Improve IPv6 checks for IPsec policies and make them consistent
with IPv4.
<li>Refactor local IP delivery to process IPsec packets in a flow.
Avoid that they are enqueued a second time.
<li><a href="https://man.openbsd.org/pf.4">pf(4)</a>
looks into AH packets and matches on the inner protocol.
This makes IPv4 authentication headers work like IPv6.
<li>The length of extension header chains in pf(4) is limited.
This prevents spending excessive cpu time on crafted packets.
<li>Block IPv6 packets in pf(4) that have hop-by-hop options
header or destination options header.
Such packets can be passed by adding "allow-opts" to the
rule.
So IPv6 options are handled like their counterpart in IPv4
now.
<li>If the IPv4 ID gets reused to fast, pf(4) fragment reassembly
uses a smarter strategy to drop packets.
<li>...
</ul>
<p>
<li>Installer improvements:
<ul>
<li> The installer now uses the Allotment Routing Table (ART).
<li> A unique kernel is now created by the installer to boot from after install/upgrade.
<li> On release installs of architectures supported by syspatch "syspatch -c" is added to rc.firsttime.
<li> Backwards compatibility code to support the 'rtsol' keyword in hostname.if(5) has been removed.
<li> The install.site and upgrade.site scripts are now executed at the end of the install/upgrade process.
<li> More detailed information is shown to identify disks.
<li> The IPv6 default router selection has been fixed.
<li>...
</ul>
<p>
<li>Routing daemons and other userland network improvements:
<ul>
<li> A new daemon, <a
href="https://man.openbsd.org/slaacd.8">slaacd(8)</a> handles IPv6
Stateless Address Autoconfiguration (RFC 4862).
<li> <a href="https://man.openbsd.org/rtadvd.8">rtadvd(8)</a> now supports
"Reducing Energy Consumption of Router Advertisements" (RFC 7772).
<li><a href="https://man.openbsd.org/ipsecctl.8">ipsecctl(8)</a>
can show SA bundles now.
The keyword "bundle" allows to create them explicitly.
This avoids confusion as they were used implicitly before.
<li><a href="https://man.openbsd.org/nc.1">nc(1)</a>
has got the option -W "recvlimit" to terminate netcat after
receiving a number of packets.
This allows to send a UDP request, receive a reply and check
the result on the command line.
<li>Fix a bunch of races in
<a href="https://man.openbsd.org/relayd.8">relayd(8)</a>
expecially in HTTP chunked mode.
<li>...
</ul>
<p>
<li>Security improvements:
<ul>
<li>A new function
<a href="https://man.openbsd.org/freezero.3">freezero(3)</a>
to easily clear and free memory holding sensitive data has been added.
<li>Double free detection has been improved when the F
<a href="https://man.openbsd.org/malloc.3">malloc(3)</a> option is used.
The existing S option now includes F.
<li>The <a href="https://man.openbsd.org/tty.4#TIOCSTI">TIOCSTI</a>
tty ioctl has been removed. The I/O-loops in the last two consumers
<a href="https://man.openbsd.org/csh.1">csh(1)</a> and
<a href="https://man.openbsd.org/mail.1">mail(1)</a>
were rewritten to cope with the removal.
<li>Trapsleds, a new mitigation that significantly reduces the amount of
nops in the instruction stream, converting them to traps, making it
harder to target potential gadgets.
<li>Kernel Address Randomized Link (KARL), a new "link-kit" allows the .o
files of the kernel to be relinked in a random order, creating a unique
kernel for each boot.
<li>Like with libc previously,
<a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links libcrypto on
startup, placing the objects in a random order.
<li>In addition to libcrypto, to deter code reuse exploits,
<a href="https://man.openbsd.org/rc.8">rc(8)</a> re-links
<a href="https://man.openbsd.org/ld.so.1">ld.so</a> on
startup, placing the objects in a random order.
<li>If process accounting is activated with
<a href="https://man.openbsd.org/accton.8">accton(8)</a>,
the daily mail shows pledge violations and program crashes.
<a href="https://man.openbsd.org/lastcomm.8">lastcomm(8)</a>
uses the flags P and T for such processes.
</ul>
<p>
<li><a href="https://man.openbsd.org/dhclient.8">dhclient(8)</a>/
<a href="https://man.openbsd.org/dhcpd.8">dhcpd(8)</a>/
<a href="https://man.openbsd.org/dhcrelay.8">dhcrelay(8)</a> improvements:
<ul>
<li>...
</ul>
<p>
<li>Assorted improvements:
<ul>
<li>Improved UTF-8 line editing support for
<a href="https://man.openbsd.org/ksh.1">ksh(1)</a>
Emacs and Vi input mode.
<li>The HISTFILE of <a href="https://man.openbsd.org/ksh.1">ksh(1)</a> now uses
a plain text format. Support for the
<a href="https://man.openbsd.org/ksh#HISTCONTROL">HISTCONTROL</a>
environment variable was added.
<li>New <a href="https://man.openbsd.org/futex">futex(2)</a> syscall
<li>New pthread <a href="https://man.openbsd.org/pthread_mutex_init">mutex</a>
and <a href="https://man.openbsd.org/pthread_cond_init">condition variable</a>
implementations improving latency of threaded applications
<li>New <a href="https://man.openbsd.org/ctfdump">ctfdump</a>
and <a href="https://man.openbsd.org/ctfconv">ctfconv</a> tools to manipulate
CTF (Compact C Type Format).
<li>The error handling in
<a href="https://man.openbsd.org/syslogd.8">syslogd(8)</a>
has been improved.
Even if internal errors occur, the deamon tries to keep
unaffected subsystems active.
So as many messages as possible are logged.
They can be filtered by severity and facility "syslog".
<li>syslogd(8) can now suppress "last message repeated" which is
useful for remote logging.
<li>syslogd(8) can listen on multiple TLS sockets.
<li>syslogd(8) closes the *.514 UDP sockets when they are not
needed.
<li>Truncate log messates at 8192 bytes everywhere.
<li>Nested mount points are umounted in correct order.
</ul>
<p>
<li>OpenSMTPD X.X.X
<ul>
<li>...
</ul>
<p>
<li>OpenSSH 7.X
<ul>
<li>Security:
<ul>
<li>...
</ul>
<li>New/changed features:
<ul>
<li>Add RemoteCommand option to specify a command in the
<a href="https://man.openbsd.org/ssh.1">ssh(1)</a>
config file instead of giving it on the client's command
line.
The feature allows to automate tasks using ssh config.
<li>...
</ul>

If your machine can boot from CD, you can write <i>install62.iso</i> or
<i>cd62.iso</i> to a CD and boot from it.
You may need to adjust your BIOS options first.
<p>
<li>
If your machine can boot from USB, you can write <i>install62.fs</i> or
<i>miniroot62.fs</i> to a USB stick and boot from it.
<p>
<li>
If you can't boot from a CD, floppy disk, or USB,
you can install across the network using PXE as described in
the included INSTALL.i386 document.
<p>
<li>
If you are planning on dual booting OpenBSD with another OS, you will need to
read INSTALL.i386.

To install, burn cd62.iso on a CD-R, put it in the CD drive of your
machine and select <i>Install System Software</i> from the System Maintenance
menu. Indigo/Indy/Indigo2 (R4000) systems will not boot automatically from
CD-ROM, and need a proper invocation from the PROM prompt.
Refer to the instructions in INSTALL.sgi for more details.
<p>
<li>
If your machine doesn't have a CD drive, you can setup a DHCP/tftp network
server, and boot using "bootp()/bsd.rd.IP##" using the kernel matching your
system type. Refer to the instructions in INSTALL.sgi for more details.

Burn the image from a mirror site to a CDROM, boot from it, and type
<i>boot cdrom</i>.
<p>
<li>
If this doesn't work, or if you don't have a CDROM drive, you can write
<i>floppy62.fs</i> or <i>floppyB62.fs</i>
(depending on your machine) to a floppy and boot it with <i>boot
floppy</i>. Refer to INSTALL.sparc64 for details.
<p>
<li>
Make sure you use a properly formatted floppy with NO BAD BLOCKS or your install
will most likely fail.
<p>
<li>
You can also write <i>miniroot62.fs</i> to the swap partition on
the disk and boot with <i>boot disk:b</i>.
<p>
<li>
If nothing works, you can boot over the network as described in INSTALL.sparc64.

<h3 id="upgrade"><font color="#0000e0">How to upgrade</font></h3>
If you already have an OpenBSD 6.1 system, and do not want to reinstall,
upgrade instructions and advice can be found in the
<a href="faq/upgrade62.html">Upgrade Guide</a>.
<p>
<hr>
<h3 id="sourcecode"><font color="#0000e0">Notes about the source code</font></h3>
<tt>src.tar.gz</tt> contains a source archive starting at <tt>/usr/src</tt>.
This file contains everything you need except for the kernel sources,
which are in a separate archive.
To extract:
<blockquote><pre>
# <b>mkdir -p /usr/src</b>
# <b>cd /usr/src</b>
# <b>tar xvfz /tmp/src.tar.gz</b>
</pre></blockquote>
<tt>sys.tar.gz</tt> contains a source archive starting at <tt>/usr/src/sys</tt>.
This file contains all the kernel sources you need to rebuild kernels.
To extract:
<blockquote><pre>
# <b>mkdir -p /usr/src/sys</b>
# <b>cd /usr/src</b>
# <b>tar xvfz /tmp/sys.tar.gz</b>
</pre></blockquote>
Both of these trees are a regular CVS checkout. Using these trees it
is possible to get a head-start on using the anoncvs servers as
described <a href="anoncvs.html">here</a>.
Using these files
results in a much faster initial CVS update than you could expect from
a fresh checkout of the full OpenBSD source tree.
<p>
<hr>
<h3 id="ports"><font color="#0000e0">Ports Tree</font></h3>
A ports tree archive is also provided. To extract:
<blockquote><pre>
# <b>cd /usr</b>
# <b>tar xvfz /tmp/ports.tar.gz</b>
</pre></blockquote>
Go read the <a href="faq/ports/index.html">ports</a> page
if you know nothing about ports
at this point. This text is not a manual of how to use ports.
Rather, it is a set of notes meant to kickstart the user on the
OpenBSD ports system.
<p>
The <i>ports/</i> directory represents a CVS checkout of our ports.
As with our complete source tree, our ports tree is available via
<a href="anoncvs.html">AnonCVS</a>.
So, in order to keep up to date with the <i>-stable</i> branch, you must make
the <i>ports/</i> tree available on a read-write medium and update the tree
with a command like:
<blockquote><pre>
# <b>cd /usr/ports</b>
# <b>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_2</b>
</pre></blockquote>
[Of course, you must replace the server name here with a nearby anoncvs
server.]
<p>
Note that most ports are available as packages on our mirrors. Updated
ports for the 6.2 release will be made available if problems arise.
<p>
If you're interested in seeing a port added, would like to help out, or just
would like to know more, the mailing list
<a href="mail.html">ports@openbsd.org</a> is a good place to know.
