*** 513,568 ****
  
  <li>IEEE 802.11 wireless stack improvements and bugfixes:
    <ul>
-     <li>Fixed an automatic Tx rate control issue in <a
- 	href="https://man.openbsd.org/iwn">iwn(4)</a>.
      <li>Fixed a bug where outstanding frames on the <a
  	href="https://man.openbsd.org/iwn">iwn(4)</a> aggregation queue
! 	interfere with roaming to another AP.
      <li>Implemented a workaround for missing Tx completion interrupts
  	in <a href="https://man.openbsd.org/iwm">iwm(4)</a> which could lead
! 	to failed decisions to roam to other APs.
!     <li>Reenabled firmware-based Tx retries at lower rates for <a
  	href="https://man.openbsd.org/iwm">iwm(4)</a>, reducing packet loss.
!     <li>Fixed an automatic Tx rate control issue in <a
! 	href="https://man.openbsd.org/iwm">iwm(4)</a> and <a
! 	href="https://man.openbsd.org/iwx">iwx(4)</a>.
!     <li>Worked around a race condition in <a
  	href="https://man.openbsd.org/iwm">iwm(4)</a> Rx interrupt handling.
!     <li>Added support for active scan to <a
  	href="https://man.openbsd.org/bwfm">bwfm(4)</a>.
!     <li>Increased throughput of the ifq pressure drop mechanism for <a
! 	href="https://man.openbsd.org/bwfm">bwfm(4)</a>.
      <li>Improved error handling for <a
  	href="https://man.openbsd.org/bwfm">bwfm(4)</a> connection attempts.
      <li>Fixed the <a
  	href="https://man.openbsd.org/ifconfig">ifconfig(8)</a> "media:" line
! 	for 11n wifi interfaces during and after a background scan.
!     <li>Fixed an mbuf corruption issue in net80211 hostap mode when overlarge SSIDs are used.
!     <li>Stopped switching to new APs found during background scans
! 	with RSSI levels which will also trigger background scans, helping to
! 	prevent repeated switching in areas where APs are tuned for low
! 	transmit range.
!     <li>Increased the net80211 node cache size.
!     <li>Reduced stalling with lossy wifi by improving net80211
! 	handling of the Rx block ack sequence number window and queue.
      <li>Prevented a crash in ieee80211_node2req() which could be
  	triggered by an <a href="https://man.openbsd.org/ioctl">ioctl(2)</a>
  	if the driver had not yet initialized the channel map.
!     <li>Stopped connecting to available open wifi networks when an
  	interface is marked up. This behavior must now be explicitly enabled
  	with <code><a href="https://man.openbsd.org/ifconfig">ifconfig(8)</a> join
  	""</code>.
!     <li>Lowered the priority of APs which fail to connect in the <a
! 	href="https://man.openbsd.org/ifconfig">ifconfig(8)</a> join list,
! 	allowing switching wifi networks by moving between them without having
! 	to down/up the interface or suspend/resume.
!     <li>Triggered a background scan when root runs the <a
! 	href="https://man.openbsd.org/ifconfig">ifconfig(8)</a> scan command,
! 	updating the list of cached APs for future scans and forcing a search
! 	for a better AP to roam to.
      <li>Raised net80211's "beacon miss" threshold to avoid frequent
! 	reconnects to APs suffering packet loss due to distance.
!     <li>Made background scans less frequent when choosing the same AP.
    </ul>
  
  <li>Generic network stack improvements and bugfixes:

!     <li>Fix kernel crashes in net802111 hostap mode due to mbuf corruption

! 	are tuned for low transmit range.

      <li>Raised net80211's "beacon miss" threshold to avoid frequent
! 	reconnects under conditions which cause loss of beacons.
