• Added 2 boot-args
  • -novht: Disables 802.11AC support
  • -noht40: Disables 40MHz when using 2.4GHz (Use this option if the network with this config causes instabilities. BRCM cards disable 2.4GHz HT40 by default)

• Added support for more Killer Wi-Fi cards
• iwx: Expanded compatibility for new APIs used in newer versions of firmware

• Implemented MAC Address Changing. It is now possible to change the MAC Address using ifconfig
• iwm/iwx: Polished support for LDPC
• iwn: Added support for Centrino Wireless-N 6150
• iwm: Fixed performance issues on 316x & 726x cards caused by misconfigured LDPC

• Fix firmware crash when receive deauth/disassoc frames, eg: connected AP disappear suddenly.
• Fix WPA2/WPA3 mixed mode connection performance.
