Johannes Berg says:

====================
Various updates, notably:
 * extended key ID support (from 802.11-2016)
 * per-STA TX power control support
 * mac80211 TX performance improvements
 * HE (802.11ax) updates
 * mesh link probing support
 * enhancements of multi-BSSID support (also related to HE)
 * OWE userspace processing support
