Among various cleanups and improvements, we have the following: 

* client FILS authentication support in mac80211 (Jouni)
  * AP/VLAN multicast improvements (Michael Braun)
  * config/advertising support for differing beacon intervals on
    multiple virtual interfaces (Purushottam Kushwaha, myself)
  * deprecate the old WDS mode for cfg80211-based drivers, the
    mode is hardly usable since it doesn't support any "modern"
    features like WPA encryption (2003), HT (2009) or VHT (2014),
    I'm not even sure WEP (introduced in 1997) could be done.

help
This option enables the deprecated WDS support, the newer
mac80211-based 4-addr AP/client support supersedes it with
a much better feature set (HT, VHT, ...)
We plan to remove this option and code, so if you find
that you have to enable it, please let us know on the
linux-wireless@vger.kernel.org mailing list, so we can
help you migrate to 4-addr AP/client (or, if it's really
necessary, give up on our plan of removing it).
