      The HT block ack receive buffer logic follows the algorithm given
          in the 802.11-2012 spec more closely.
!     
The iwn(4) driver now
          keeps track of HT protection changes while associated to an 11n AP.
      
The wireless stack and several drivers make more aggressive use
          of RTS/CTS to avoid interference from legacy devices and hidden nodes.
!     
The netstat(1) -W
          command now shows information about 802.11n events.

          still cached. Fixes a problem where an access point using the
!         ral(4) driver
          would get stuck at 1 Mbps because Tx rate accounting happened
          on the wrong node object.

The prio field on VLAN headers is now correctly set on each fragment

Enabled device cloning for

          This allows the system to have just one bpf device node in /dev
          that services all bpf consumers (up to 1024).
      
The Tx queue of the

! 	fopen(3).
      
PT_TLS sections are now supported in initially loaded object.
      
Improved handling of "no paths" and "empty path" in
! 	fts(3).
!     
In pcap(3),
          provide the functions pcap_free_datalinks()
          and pcap_offline_filter().
      
Many bugfixes and structural cleanup in the
!         editline(3) library.
      
Remove ancient
!         dbm(3)
          functions;
!         ndbm(3) remains.
      
Add setenv keyword for more powerful environment handling in
!         doas.conf(5).
      
Add -g and -p options to
!         aucat.1
          for time positioning.
!     
Rewrite audioctl(1)
          with a simpler user interface.
      
Add -F option to
!         install(1)
!         to fsync(2)
          the file before closing it.
!     
kdump(1)
  	now dumps pollfd structures.
      
Improve various details of
!         ksh(1) POSIX compliance.
!     
mknod(8) rewritten in a
!         pledge(2)-friendly
          style and to support creating multiple devices at once.
!     
Implement rcctl(8)
          get all and getdef all.
!     
Implement the rcs(1)
          -I (interactive) flag.
!     
In rcs(1),
          implement Mdocdate keyword substitution.
!     
In top(1),
          allow to filter process arguments if they are being displayed.
      
Added UTF-8 support to
!         fold(1) and
!         rev(1).
      
Enable UTF-8 by default in
!         xterm(1) and
!         pod2man(1).
      
Filter out non-ASCII characters in
!         wall(1).
!     
Handle the COLUMNS
          environment variable consistently across many programs.
      
The options -c and -k allow to provide
          TLS client certificates for
!         syslogd(8)
          on the sending side.
          With that the receiving side can verify log messages
          are authentic.

sshd(8):
