          (CTRL-EVENT-EAP-PEER-ALT)

          HT/VHT/specific TX rate support)

        * added fully automated regression testing with mac80211_hwsim
        * changed configuration parser to reject invalid integer values
        * allow AP/Enrollee to be specified with BSSID instead of UUID for
          WPS ER operations
        * disable network block temporarily on repeated connection failures
        * changed the default driver interface from wext to nl80211 if both are
          included in the build
        * remove duplicate networks if WPS provisioning is run multiple times
        * remove duplicate networks when Interworking network selection uses the
          same network
        * added global freq_list configuration to allow scan frequencies to be
          limited for all cases instead of just for a specific network block
        * added support for BSS Transition Management
        * added option to use "IFNAME=<ifname> " prefix to use \ 
the global
          control interface connection to perform per-interface commands;
          similarly, allow global control interface to be used as a monitor
          interface to receive events from all interfaces
        * fixed OKC-based PMKSA cache entry clearing
        * fixed TKIP group key configuration with FT
        * added support for using OCSP stapling to validate server certificate
          (ocsp=1 as optional and ocsp=2 as mandatory)
        * added EAP-EKE peer
        * added peer restart detection for IBSS RSN
        * added domain_suffix_match (and domain_suffix_match2 for Phase 2
          EAP-TLS) to specify additional constraint for the server certificate
          domain name
        * added support for external SIM/USIM processing in EAP-SIM, EAP-AKA,
          and EAP-AKA' (CTRL-REQ-SIM and CTRL-RSP-SIM commands over control
          interface)
        * added global bgscan configuration option as a default for all network
          blocks that do not specify their own bgscan parameters
        * added D-Bus methods for TDLS
        * added more control to scan requests
          - "SCAN freq=<freq list>" can be used to specify which \ 
channels are
            scanned (comma-separated frequency ranges in MHz)
          - "SCAN passive=1" can be used to request a passive scan (no \ 
Probe
            Request frames are sent)
          - "SCAN use_id" can be used to request a scan id to be \ 
returned and
            included in event messages related to this specific scan operation
          - "SCAN only_new=1" can be used to request the driver/cfg80211 to
            report only BSS entries that have been updated during this scan
            round
          - these optional arguments to the SCAN command can be combined with
            each other
        * modified behavior on externally triggered scans
          - avoid concurrent operations requiring full control of the radio when
            an externally triggered scan is detected
          - do not use results for internal roaming decision
        * added a new cred block parameter 'temporary' to allow credential
          blocks to be stored separately even if wpa_supplicant configuration
          file is used to maintain other network information
        * added "radio work" framework to schedule exclusive radio \ 
operations
          for off-channel functionality
          - reduce issues with concurrent operations that try to control which
            channel is used
          - allow external programs to request exclusive radio control in a way
            that avoids conflicts with wpa_supplicant
        * added support for using Protected Dual of Public Action frames for
          GAS/ANQP exchanges when associated with PMF
        * added support for WPS+NFC updates and P2P+NFC
          - improved protocol for WPS
          - P2P group formation/join based on NFC connection handover
          - new IPv4 address assignment for P2P groups (ip_addr_* configuration
            parameters on the GO) to replace DHCP
          - option to fetch and report alternative carrier records for external
            NFC operations
        * various bug fixes
