+ [http://w1.fi/security/2015-2/] (CVE-2015-4141)
+ * fixed WMM Action frame parser
+ [http://w1.fi/security/2015-3/] (CVE-2015-4142)
+ * fixed EAP-pwd server missing payload length validation
+ [http://w1.fi/security/2015-4/]
+ (CVE-2015-4143, CVE-2015-4144, CVE-2015-4145)
+ * fixed validation of WPS and P2P NFC NDEF record payload length
+ [http://w1.fi/security/2015-5/]
+ * nl80211:
+ - fixed vendor command handling to check OUI properly
+ * fixed hlr_auc_gw build with OpenSSL
+ * hlr_auc_gw: allow Milenage RES length to be reduced
+ * disable HT for a station that does not support WMM/QoS
+ * added support for hashed password (NtHash) in EAP-pwd server
+ * fixed and extended dynamic VLAN cases
+ * added EAP-EKE server support for deriving Session-Id
+ * set Acct-Session-Id to a random value to make it more likely to be
+ unique even if the device does not have a proper clock
+ * added more 2.4 GHz channels for 20/40 MHz HT co-ex scan
+ * modified SAE routines to be more robust and PWE generation to be
+ stronger against timing attacks
+ * added support for Brainpool Elliptic Curves with SAE
+ * increases maximum value accepted for cwmin/cwmax
+ * added support for CCMP-256 and GCMP-256 as group ciphers with FT
+ * added Fast Session Transfer (FST) module
+ * removed optional fields from RSNE when using FT with PMF
+ (workaround for interoperability issues with iOS 8.4)
+ * added EAP server support for TLS session resumption
+ * fixed key derivation for Suite B 192-bit AKM (this breaks
+ compatibility with the earlier version)
+ * added mechanism to track unconnected stations and do minimal band
+ steering
+ * number of small fixes
+
+2015-03-15 - v2.4
+ * allow OpenSSL cipher configuration to be set for internal EAP server
+ (openssl_ciphers parameter)
+ * fixed number of small issues based on hwsim test case failures and
+ static analyzer reports
+ * fixed Accounting-Request to not include duplicated Acct-Session-Id
+ * add support for Acct-Multi-Session-Id in RADIUS Accounting messages
+ * add support for PMKSA caching with SAE
+ * add support for generating BSS Load element (bss_load_update_period)
+ * fixed channel switch from VHT to HT
+ * add INTERFACE-ENABLED and INTERFACE-DISABLED ctrl_iface events
+ * add support for learning STA IPv4/IPv6 addresses and configuring
+ ProxyARP support
+ * dropped support for the madwifi driver interface
+ * add support for Suite B (128-bit and 192-bit level) key management and
+ cipher suites
+ * fixed a regression with driver=wired
+ * extend EAPOL-Key msg 1/4 retry workaround for changing SNonce
+ * add BSS_TM_REQ ctrl_iface command to send BSS Transition Management
+ Request frames and BSS-TM-RESP event to indicate response to such
+ frame
+ * add support for EAP Re-Authentication Protocol (ERP)
+ * fixed AP IE in EAPOL-Key 3/4 when both WPA and FT was enabled
+ * fixed a regression in HT 20/40 coex Action frame parsing
+ * set stdout to be line-buffered
+ * add support for vendor specific VHT extension to enable 256 QAM rates
+ (VHT-MCS 8 and 9) on 2.4 GHz band
+ * RADIUS DAS:
+ - extend Disconnect-Request processing to allow matching of multiple
+ sessions
+ - support Acct-Multi-Session-Id as an identifier
+ - allow PMKSA cache entry to be removed without association
+ * expire hostapd STA entry if kernel does not have a matching entry
+ * allow chanlist to be used to specify a subset of channels for ACS
+ * improve ACS behavior on 2.4 GHz band and allow channel bias to be
+ configured with acs_chan_bias parameter
+ * do not reply to a Probe Request frame that includes DSS Parameter Set
+ element in which the channel does not match the current operating
+ channel
+ * add UPDATE_BEACON ctrl_iface command; this can be used to force Beacon
+ frame contents to be updated and to start beaconing on an interface
+ that used start_disabled=1
+ * fixed some RADIUS server failover cases
+
2014-10-09 - v2.3
* fixed number of minor issues identified in static analyzer warnings
* fixed DFS and channel switch operation for multi-BSS cases
