We have a number of changes, but things are settling down:

Browse source 
* a fix in the new 6 GHz channel support
  * a fix for recent minstrel (rate control) updates
    for an infinite loop
  * handle interface type changes better wrt. management frame
    registrations (for management frames sent to userspace)
  * add in-BSS RX time to survey information
  * handle HW rfkill properly if !CONFIG_RFKILL
  * send deauth on IBSS station expiry, to avoid state mismatches
  * handle deferred crypto tailroom updates in mac80211 better
    when device restart happens
  * fix a spectre-v1 - really a continuation of a previous patch
  * advertise NL80211_CMD_UPDATE_FT_IES as supported if so
  * add some missing parsing in VHT extended NSS support
  * support HE in mac80211_hwsim
  * let mac80211 drivers determine the max MTU themselves
 along with the usual cleanups etc.
