<li>Don't print the device name twice in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=yds&manpath=OpenBSD%20Current&sektion=4&format=html">yds(4)</a> attach error messages.
<li>Added many regression tests for rthreads.
<li>The <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tmux&manpath=OpenBSD%20Current&sektion=1&format=html">tmux(1)</a> command <code>paste-buffer</code> now offers a <code>-p</code> option to enable "bracketed paste" mode.
<li>The <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tmux&manpath=OpenBSD%20Current&sektion=1&format=html">tmux(1)</a> wlmouse offset is now corrected to be part of the client, not the server.
<li>Add <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tmux&manpath=OpenBSD%20Current&sektion=1&format=html">tmux(1)</a> <code>move-pane</code> command (like <code>join-pane</code> but allows the same window).

<!-- 2012/03/02 -->
<li>Fix handling of "offend" (OFFset from the END of the arg list) arguments in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=systrace&manpath=OpenBSD%20Current&sektion=1&format=html">systrace(1)</a>.

<li>Let <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=malloc&manpath=OpenBSD%20Current&sektion=3&format=html">malloc(3)</a> test for the retrieved page address not being NULL. This turns free((void*)1) into an bogus pointer error instead of a segfault.
<!-- 2012/02/28 -->
<li>Support the Roland UM-ONE <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=umidi&manpath=OpenBSD%20Current&sektion=4&format=html">umidi(4)</a> device.
<li>Update to pixman 0.22.4, <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=xev&manpath=OpenBSD%20Current&sektion=1&format=html">xev(1)</a> 1.2.0, <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=xwd&manpath=OpenBSD%20Current&sektion=1&format=html">xwd(1)</a> 1.0.5, and <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=xwininfo&manpath=OpenBSD%20Current&sektion=1&format=html">xwininfo(1)</a> 1.1.2.
<li>Luna88k multi-processor support, step 3. GENERIC.MP configuration file based on mvme88k.
<li>Add <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mos&manpath=OpenBSD%20Current&sektion=4&format=html">mos(4)</a> support for the MosChip MCS7832, a low pin count version of the MCS7830.
<li>Updated the list of supported four digit models in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=intro&manpath=OpenBSD%20Current&sektion=4&arch=hppa&format=html">intro(4/hppa)</a>.
<li>Mention in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=se&manpath=OpenBSD%20Current&sektion=4&format=html">se(4)</a> some additional phys (physical layer interfaces) that may be able to attach.

<li>Add checks to rthreads when trying to unlock an uninitialized mutex to make sure it returns EPERM.
<!-- 2012/02/26 -->
<li>The <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mandoc&manpath=OpenBSD%20Current&sektion=1&format=html">mandoc(1)</a> program now replaces bogus characters with <code>?</code> instead of just dropping them.
<li>In <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=man&manpath=OpenBSD%20Current&sektion=7&format=html">man(7)</a>, support the <code>.OP</code> macro (for compatibility only).
<li>On the mips64 and sh platforms the per-thread errno should be fixed.
<li>The <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ix&manpath=OpenBSD%20Current&sektion=4&format=html">ix(4)</a> interrupt routine uses a shorter path to reenable interrupts and gains other tweaks which result in a doubled performance on 82599.
<!-- 2012/02/25 -->
<li>In the <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=gus&manpath=OpenBSD%20Current&sektion=4&arch=i386&format=html">gus(4/i386)</a> driver MIDI registers will only be used if they are actually available. This fixes an issue which caused the driver to be disabled on 1999-08-22, but the happy-end can finally be seen in i386 GENERIC.
<li>For the <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=elroy&manpath=OpenBSD%20Current&sektion=4&arch=hppa&format=html">elroy(4/hppa)</a> driver an integer truncation error is fixed which caused systems to freeze hard.
<li>The process tracing facilities will work again on processors without floating-point registers/state. (Had been broken by the large extension of the 20th.)
<li>In <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tmux&manpath=OpenBSD%20Current&sektion=1&format=html">tmux(1)</a> the <code>show-options</code> and <code>window-show-options</code> commands can now be used to show just a single specified option.
<li>Minor tweaks and cleanups in the amd64 code of the kernel have been observed.
<!-- 2012/02/24 -->
<!-- 2012/02/23 -->
<li>pthread_yield(3) is renamed to sched_yield(3).
<li>Manual pages are created for the <code>pthread_condattr_t</code> type.
<li>The <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tmux&manpath=OpenBSD%20Current&sektion=1&format=html">tmux(1)</a> <code>display-message</code> command is extended by a <b>-F</b> option which can be used to specify a format string to control output formatting.
<li>New functions are added to the thread library: pthread_mutex_timedlock(3), pthread_condattr_getclock(3) and pthread_condattr_setclock(3); also, <code>PTHREAD_MUTEX_NORMAL</code> mutexes learn about self-deadlocks.
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=snmpd&manpath=OpenBSD%20Current&sektion=8&format=html">snmpd(8)</a> gains the MIB module for gathering information from OpenBSD's packet filter.
<!-- 2012/02/22 -->
<li>In <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=chroot&manpath=OpenBSD%20Current&sektion=2&format=html">chroot(2)</a> mode nginx(8) first <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=chdir&manpath=OpenBSD%20Current&sektion=2&format=html">chdir(2)</a>s to the <code>PREFIX</code> directory before it starts to create it's temporary directories.
<!-- 2012/02/21 -->
<li>The pthread_suspend_np(3) and pthread_resume_np(3) function are no longer functional and become <code>ENOTSUP</code> stubs.
<!-- 2012/02/20 -->
<li>A lot of work is being done for making process tracing work with rthreads.
<li>In Xenocara, update xf86-video-geode 2.11.13 and xf86-video-dummy to 0.3.5.
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=kdump&manpath=OpenBSD%20Current&sektion=1&format=html">kdump(1)</a> fixes an integer flip which could have happened for a kernel trace record with <code>ktr_len</code> of <code>SIZE_MAX</code> and would have caused a zero byte data allocation. It also learns more system calls and refactors output routines as well as the output produced by the latter.
<li>A lot of work is being done on regression tests for threads.
<!-- 2012/02/19 -->
<li>Bugfix in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=tcpdump&manpath=OpenBSD%20Current&sektion=8&format=html">tcpdump(8)</a> to correctly check BGP prefix lengths in withdrawn routes.
<li>Fix return value documentation errors in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=usbhid&manpath=OpenBSD%20Current&sektion=3&format=html">usbhid(3)</a>.
<li>Allow for more vars in <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=ksh&manpath=OpenBSD%20Current&sektion=1&format=html">ksh(1)</a> hash table, improve hash function, increase hash table size sooner.
<!-- 2012/02/18 -->
<li>Initialize the scope, policy, and inherit members in pthread_attr_init() so that their pthread_attr_get* don't return bogus values.
<li>Update nginx in base to 1.0.12 and sync its <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pcre&manpath=OpenBSD%20Current&sektion=3&format=html">pcre(3)</a> with the version in ports.
<li>Update to <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mkfontdir&manpath=OpenBSD%20Current&sektion=1&format=html">mkfontdir(1)</a> 1.0.7, <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=mkfontscale&manpath=OpenBSD%20Current&sektion=1&format=html">mkfontscale(1)</a> 1.1.0, <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=oclock&manpath=OpenBSD%20Current&sektion=1&format=html">oclock(1)</a> 1.0.3, <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=xclipboard&manpath=OpenBSD%20Current&sektion=1&format=html">xclipboard(1)</a> 1.1.2, <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=xclock&manpath=OpenBSD%20Current&sektion=1&format=html">xclock(1)</a> 1.0.6, <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=xcmsdb&manpath=OpenBSD%20Current&sektion=1&format=html">xcmsdb(1)</a> 1.0.4, <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=xcompmgr&manpath=OpenBSD%20Current&sektion=1&format=html">xcompmgr(1)</a> 1.1.6, <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=xfd&manpath=OpenBSD%20Current&sektion=1&format=html">xfd(1)</a> to 1.1.1 and util-macros to 1.16.1.
<!-- 2012/02/17 -->
<li>Add DIAGNOSTICS to <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=bsd.port.mk&manpath=OpenBSD%20Current&sektion=5&format=html">bsd.port.mk(5)</a>, for easy grepping through logs, and no longer label "warning messages" as "errors".
<!-- 2012/02/16 -->
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pkill&manpath=OpenBSD%20Current&sektion=1&format=html">pkill(1)</a> will now exit usage() with STATUS_BADUSAGE rather than STATUS_ERROR, in agreement with the man page.

<li>Hold struct filedesc's fd_lock in more places. Fixes hangs in rthreaded processes calling <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=fork&manpath=OpenBSD%20Current&sektion=2&format=html">fork(2)</a>.
<li>No longer attempt to enable MSI on 82571/82572 <a href="http://www.openbsd.org/cgi-bin/man.cgi?query=em&manpath=OpenBSD%20Current&sektion=4&format=html">em(4)</a> Gigabit ethernet controllers (to workaround "Byte Enables 2 and 3 Are Not Set" hardware bug).
<!-- 2012/02/13 -->
<li><a href="http://www.openbsd.org/cgi-bin/man.cgi?query=pkg_create&manpath=OpenBSD%20Current&sektion=1&format=html">pkg_create(1)</a> now warns when <code>@option no-default-conflict</code> has been set without explicit <code>@conflict</code>.
