71: <h3>What's New</h3>
72: <p>
73: This is a partial list of new features and systems included in OpenBSD 6.7.
74: For a comprehensive list, see the <a href="plus67.html">changelog</a> leading
75: to 6.7.
76:
77: <ul>
78:
79: <li>General improvements and bugfixes:
80: <ul>
81: <li>Reduced the minimum allowed number of chunks in a CONCAT
82: volume from 2 to 1, increasing the number of volumes which can be
83: created on a single disk with <a
84: href="https://man.openbsd.org/bioctl">bioctl(8)</a> from 7 to 15. This
85: can be used to create more partitions than previously.
86: <li>Rewrote the <a href="https://man.openbsd.org/cron">cron(8)</a>
87: flag-parsing code to be getopt-like, allowing tight formations like
88: -ns and flag repetition. Renamed the "options" field in <a
89: href="https://man.openbsd.org/crontab">crontab(5)</a> to "flags".
90: <li>Added <a
91: href="https://man.openbsd.org/man5/crontab.5">crontab(5)</a> -s flag
92: to the command field, indicating that only a single instance of the
93: job should run concurrently.
94: <li>Added <a href="https://man.openbsd.org/cron">cron(8)</a>
95: support for random values using the ~ operator.
96: <li>Allowed <a href="https://man.openbsd.org/cwm">cwm(1)</a>
97: configuration of window size based on percentage of the master window
98: during horizontal and vertical tiling actions.

100: group clients in <a href="https://man.openbsd.org/cwm">cwm(1)</a>.
101: <li>Switched powerpc to a machine-independent mplock implementation,
102: allowing use of <a href="https://man.openbsd.org/witness">
103: witness(4)</a>.
104: <li>Added <a href="https://man.openbsd.org/acpi">acpi(4)</a>
105: support for the _CCA method, indicating whether DMA is cache-coherent.
106: <li>Switched the default compiler on powerpc to clang.
107: <li>Bumped <a href="https://man.openbsd.org/nvme">nvme(4)</a> max
108: physio() i/o size to 128K.
1.57 ! jca 109: <li>Improved <a href="https://man.openbsd.org/apmd">apmd(8)</a>
! 110: support for automatic suspend/hibernate (-z/-Z). The daemon now
! 111: reacts to power changes messages sent by the battery driver.
! 112: Those messages are ignored for 60 seconds after a resume, so
! 113: that the user can take control before the machine goes back to
! 114: sleep.
1.1 benno 115: <li>Prevented a kernel hang when no unlocked ffs_softdep worklist
116: items could be processed.
117: <li>Stopped counting pages mapped as PROT_NONE against the
118: RLIMIT_DATA limit, helping code which reserves large chunks of address
119: space but populates it sparsely.
120: <li>Added the $REQUEST_SCHEME variable to <a
121: href="https://man.openbsd.org/httpd.conf">httpd.conf(5)</a>, allowing
122: preservation of the original connection type (http or https) for
123: redirect locations
124: <li>Implemented "strip" option in <a
125: href="https://man.openbsd.org/httpd.conf">httpd.conf(5)</a> for
126: fastcgi to be able to have multiple chroots under /var/www for FastCGI
127: servers.
128: <li>Changed <a href="https://man.openbsd.org/httpd">httpd(8)</a>
129: to send a 408 response when a timeout happens while headers are being
130: received, but close the connection if no request is received.
131: <li>Updated en_US.UTF-8.src to Unicode 12.1.
1.19 deraadt 132: <li>Added a new __tmpfd system call which creates a new, unnamed file in
133: /tmp, intended for shm/fd passing, but in programs that may otherwise
134: lack filesystem access (due to restrictions imposed by
135: <a href="https://man.openbsd.org/unveil.2">unveil(2)</a> or
136: <a href="https://man.openbsd.org/pledge.2">pledge(2)</a>).

155: avoid backwardly compatible behavior.
156: <li>Added the system clock interface <a
157: href="https://man.openbsd.org/nanoboottime">nanoboottime(9)</a>,
158: returning the UTC time at which the system booted in seconds and
159: nanoseconds.
160: <li>Introduced efficient page freeing in reverse order from uvm,
161: greatly improving cases of massive page freeing.
162: <li>Added uvm_objfree to uvm to efficiently free all pages from a
163: uvm object, used in the buffer cache for considerable speedup when
164: freeing pages.
165: <li>Modified buffer cache to use individual uvm_objs per buffer to
166: speed page lookups.
167: <li>Speed up <a href="https://man.openbsd.org/sort">sort(1)</a> by
168: not performing a top-level sort when -c is used with a -k field.
169: <li>Modified -z mode verification in <a
170: href="https://man.openbsd.org/signify">signify(1)</a> to save the
171: header and output it, so signify -zV >saved.tgz will keep the
172: signature for later checks.
173: <li>Enabled DNSSEC validation in <a
174: href="https://man.openbsd.org/unbound">unbound(8)</a> by default.

544: <li>Implemented a workaround for missing Tx completion interrupts
545: in <a href="https://man.openbsd.org/iwm">iwm(4)</a> which could lead
546: to failures when roaming to another AP.
547: <li>Re-enabled firmware-based Tx retries at lower rates for <a
548: href="https://man.openbsd.org/iwm">iwm(4)</a>, reducing packet loss.
549: <li>Fixed automatic Tx rate control issues in <a

599:
600: </ul>
601:
602: <li>Installer improvements:
603: <ul>
604: <li>Simplified <a
605: href="https://man.openbsd.org/sysupgrade">sysupgrade(8)</a> directory
606: check and creation (/home/_syspatch). It can now be a symlink.

1534: <section id=sourcecode>
1535: <h3>Notes about the source code</h3>
1536: <p>
1537: <code>src.tar.gz</code> contains a source archive starting at <code>/usr/src</code>.
1538: This file contains everything you need except for the kernel sources,
1539: which are in a separate archive.
1540: To extract:
1541: <blockquote><pre>
1542: # <kbd>mkdir -p /usr/src</kbd>
1543: # <kbd>cd /usr/src</kbd>
1544: # <kbd>tar xvfz /tmp/src.tar.gz</kbd>
1545: </pre></blockquote>
1546: <p>
1547: <code>sys.tar.gz</code> contains a source archive starting at <code>/usr/src/sys</code>.
1548: This file contains all the kernel sources you need to rebuild kernels.
1549: To extract:
1550: <blockquote><pre>
1551: # <kbd>mkdir -p /usr/src/sys</kbd>
1552: # <kbd>cd /usr/src</kbd>
1553: # <kbd>tar xvfz /tmp/sys.tar.gz</kbd>
1554: </pre></blockquote>
1555: <p>
1556: Both of these trees are a regular CVS checkout. Using these trees it
1557: is possible to get a head-start on using the anoncvs servers as
1558: described <a href="anoncvs.html">here</a>.
1559: Using these files
1560: results in a much faster initial CVS update than you could expect from
1561: a fresh checkout of the full OpenBSD source tree.

1567: <h3>Ports Tree</h3>
1568: <p>
1569: A ports tree archive is also provided. To extract:
1570: <blockquote><pre>
1571: # <kbd>cd /usr</kbd>
1572: # <kbd>tar xvfz /tmp/ports.tar.gz</kbd>
1573: </pre></blockquote>
1574: <p>
1575: Go read the <a href="faq/ports/index.html">ports</a> page
1576: if you know nothing about ports
1577: at this point. This text is not a manual of how to use ports.
1578: Rather, it is a set of notes meant to kickstart the user on the
1579: OpenBSD ports system.
1580: <p>
1581: The <i>ports/</i> directory represents a CVS checkout of our ports.
1582: As with our complete source tree, our ports tree is available via
1583: <a href="anoncvs.html">AnonCVS</a>.
1584: So, in order to keep up to date with the -stable branch, you must make
1585: the <i>ports/</i> tree available on a read-write medium and update the tree
1586: with a command like:
1587: <blockquote><pre>
1588: # <kbd>cd /usr/ports</kbd>
1589: # <kbd>cvs -d anoncvs@server.openbsd.org:/cvs update -Pd -rOPENBSD_6_7</kbd>
1590: </pre></blockquote>
1591: <p>
1592: [Of course, you must replace the server name here with a nearby anoncvs
1593: server.]
1594: <p>
1595: Note that most ports are available as packages on our mirrors. Updated
1596: ports for the 6.7 release will be made available if problems arise.
1597: <p>
1598: If you're interested in seeing a port added, would like to help out, or just
1599: would like to know more, the mailing list
1600: <a href="mail.html">ports@openbsd.org</a> is a good place to know.
