 ChangeLog for hostapd
 
+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

 .B hostapd
 is a user space daemon for access point and authentication servers.
 It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP Authenticators and RADIUS authentication server.
-The current version supports Linux (Host AP, madwifi, mac80211-based drivers) and FreeBSD (net80211).
+The current version supports Linux (Host AP, mac80211-based drivers) and FreeBSD (net80211).
 
 .B hostapd
 is designed to be a "daemon" program that runs in the background and acts as the backend component controlling authentication.

 ChangeLog for wpa_supplicant
 
+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
+	* P2P:
+	  - add new=<0/1> flag to P2P-DEVICE-FOUND events
+	  - add passive channels in invitation response from P2P Client
+	  - enable nl80211 P2P_DEVICE support by default
+	  - fix regresssion in disallow_freq preventing search on social
+	    channels
+	  - fix regressions in P2P SD query processing
+	  - try to re-invite with social operating channel if no common channels
+	    in invitation
+	  - allow cross connection on parent interface (this fixes number of
+	    use cases with nl80211)
+	  - add support for P2P services (P2PS)
+	  - add p2p_go_ctwindow configuration parameter to allow GO CTWindow to
+	    be configured
+	* increase postponing of EAPOL-Start by one second with AP/GO that
+	  supports WPS 2.0 (this makes it less likely to trigger extra roundtrip
+	  of identity frames)
+	* add support for PMKSA caching with SAE
+	* add support for control mesh BSS (IEEE 802.11s) operations
+	* fixed number of issues with D-Bus P2P commands
+	* fixed regression in ap_scan=2 special case for WPS
+	* fixed macsec_validate configuration
+	* add a workaround for incorrectly behaving APs that try to use
+	  EAPOL-Key descriptor version 3 when the station supports PMF even if
+	  PMF is not enabled on the AP
+	* allow TLS v1.1 and v1.2 to be negotiated by default; previous behavior
+	  of disabling these can be configured to work around issues with broken
+	  servers with phase1="tls_disable_tlsv1_1=1 tls_disable_tlsv1_2=1"
+	* add support for Suite B (128-bit and 192-bit level) key management and
+	  cipher suites
+	* add WMM-AC support (WMM_AC_ADDTS/WMM_AC_DELTS)
+	* improved BSS Transition Management processing
+	* add support for neighbor report
+	* add support for link measurement
+	* fixed expiration of BSS entry with all-zeros BSSID
+	* add optional LAST_ID=x argument to LIST_NETWORK to allow all
+	  configured networks to be listed even with huge number of network
+	  profiles
+	* add support for EAP Re-Authentication Protocol (ERP)
+	* fixed EAP-IKEv2 fragmentation reassembly
+	* improved PKCS#11 configuration for OpenSSL
+	* set stdout to be line-buffered
+	* add TDLS channel switch configuration
+	* add support for MAC address randomization in scans with nl80211
+	* enable HT for IBSS if supported by the driver
+	* add BSSID black and white lists (bssid_blacklist, bssid_whitelist)
+	* add support for domain_suffix_match with GnuTLS
+	* add OCSP stapling client support with GnuTLS
+	* include peer certificate in EAP events even without a separate probe
+	  operation; old behavior can be restored with cert_in_cb=0
+	* add peer ceritficate alt subject name to EAP events
+	  (CTRL-EVENT-EAP-PEER-ALT)
+	* add domain_match network profile parameter (similar to
+	  domain_suffix_match, but full match is required)
+	* enable AP/GO mode HT Tx STBC automatically based on driver support
+	* add ANQP-QUERY-DONE event to provide information on ANQP parsing
+	  status
+	* allow passive scanning to be forced with passive_scan=1
+	* add a workaround for Linux packet socket behavior when interface is in
+	  bridge
+	* increase 5 GHz band preference in BSS selection (estimate SNR, if info
+	  not available from driver; estimate maximum throughput based on common
+	  HT/VHT/specific TX rate support)
+	* add INTERWORKING_ADD_NETWORK ctrl_iface command; this can be used to
+	  implement Interworking network selection behavior in upper layers
+	  software components
+	* add optional reassoc_same_bss_optim=1 (disabled by default)
+	  optimization to avoid unnecessary Authentication frame exchange
+	* extend TDLS frame padding workaround to cover all packets
+	* allow wpa_supplicant to recover nl80211 functionality if the cfg80211
+	  module gets removed and reloaded without restarting wpa_supplicant
+	* allow hostapd DFS implementation to be used in wpa_supplicant AP mode
+
 2014-10-09 - v2.3
 	* fixed number of minor issues identified in static analyzer warnings
 	* fixed wfd_dev_info to be more careful and not read beyond the buffer
