<li>Prevent FFS from uselessly extracting a disklabel.
<li>Improved <a href="https://man.openbsd.org/pkg_add.1">pkg_add(1)</a>.

<li>Make <code>swapctl -s</code> show 512 B blocks and show 1 KB blocks when launched with -k, as it is supposed to do. Fixed PR6609.
<li>Added a machine-independent <a href="https://man.openbsd.org/sysctl.8">sysctl(8)</a> hw.allowpowerdown: if set to 1 (the default) it allows a power button shutdown.
<li>Make sparc64 acknowledge a shared interrupt only once.
<li>Speed up <a href="https://man.openbsd.org/pkg_add.1">pkg_add(1)</a> dependency checking by not computing @wantlib on -current and by adding an extra cache and by making the checking computation progress message less painful.

<li>Avoid a possible null dereference in <a href="https://man.openbsd.org/softraid.4">softraid(4)</a>.
<li>Make <a href="https://man.openbsd.org/makewhatis.8">makewhatis(8)</a> handle \*(Na in .Nd, as it is needed by <a href="https://man.openbsd.org/nan.3">nan(3)</a>.

<li>Introduced window_raise, a new cwmrc(5) config option to raise a client via the mouse.
<li>Introduced snapdist, a new cwmrc(5) config option to snap to the screen edge.
<li>Improved <a href="https://man.openbsd.org/cwm.1">cwm(1)</a> vmax+hmax behaviour.
<li>Replaced <a href="https://man.openbsd.org/cwm.1">cwm(1)</a>  non-working check to see if another window manager is running with a method that actually works.

<li>Make <a href="https://man.openbsd.org/myx.4">myx(4)</a> resume the tx_count on UP, since it may have been advanced from non-zero by a previous use.
<li>Fixed function names in <a href="https://man.openbsd.org/wd.4">wd(4)</a> debug statements.
<li>Added beagle to distribution, thought it is not yet fully ready.
<li>Added MSI support to <a href="https://man.openbsd.org/myx.4">myx(4)</a>.
<li>In cnmac(4/OCTEON): fixed MAC address printing for <a href="https://man.openbsd.org/dmesg.8">dmesg(8)</a>, set IFCAP_VLAN_MTU to allow for VLAN sized frames.
<li>Synchronized Bind root.hint, added IPv6 address for d.root-servers.net.

<li>Added to <a href="https://man.openbsd.org/systrace.4">systrace(4)</a> a SYSTR_POLICY_KILL per-syscall policy option that sends SIGKILL to the traced process when the syscall is attempted.
<li>Make <a href="https://man.openbsd.org/uvm.9">uvm(9)</a> validate pmemrange result, enabling early catching of bugs in the code.
<!-- 2011/06/21 -->

<li>Removed message_id and message_uid from <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a>. It now has an evpid associated to each delivery message, the evpid is an u_int64_t where the upper 32 bits are the msgid, and the 32 bits are the envelope unique identifier for that message.
<li>Make sure <a href="https://man.openbsd.org/iswctype.3">iswctype(3)</a> wcwidth() return -1 if the character is not printable. Adapt <a href="https://man.openbsd.org/file.1">file(1)</a> to this behaviour.

This increases parallelism when using "make -j" and keeps the dependencies up to date with each compilation automatically.
<li>Implemented -MP, -MT and -MF options in <a href="https://man.openbsd.org/gcc.1">gcc(1)</a> so all platforms can support so-called "advanced automatic dependency generation".

<li>Make hppa64 bcopy.S and spcopy.S use 64-bit operations for address manipulation.
<li>Correctly load p_addr and avoid trashing the source address in hppa64 bcopy.S and spcopy.S.
<li>Modified <a href="https://man.openbsd.org/sis.4">sis(4)</a> interrupt handler so it only processes the rings once rather than looping over them until it runs out of work to do.
<li>Make <a href="https://man.openbsd.org/softraid.4">softraid(4)</a> sr_raid_start_stop() ignore SCSI start/stop: a <a href="https://man.openbsd.org/softraid.4">softraid(4)</a> displine should always reflect the correct status.
<!-- 2011/04/13 -->
<li>Make <a href="https://man.openbsd.org/smtpd.8">smtpd(8)</a> use a ram-queue instead of doing a continuous walk on disk-queue.
<li>Make spstrcpy() work as it should in hppa64 locore.S.
<li>Enabled <a href="https://man.openbsd.org/siop.4">siop(4)</a>, <a href="https://man.openbsd.org/scsibus.4">scsibus(4)</a> and <a href="https://man.openbsd.org/sd.4">sd(4)</a> in hppa64 GENERIC kernel.
<li>Removed noisy debug code from hppa intr.c.

<li>Fixed READ/WRITE confusion in <a href="https://man.openbsd.org/bnx.4">bnx(4)</a>.
<li>Added support for per-rthread base-offset for the %fs selector on amd64. Added pcb_fsbase to the PCB for tracking what the value for the thread is, and ci_cur_fsbase to struct cpu_info for tracking the CPU's current value for FS.base, then on return to user-space, skip the setting if the CPU has the right value already.  Non-threaded processes without TLS leave FS.base zero, which can be conveniently optimized: setting %fs zeros FS.base for fewer cycles than wrmsr.
