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

	  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"

	  status
	* allow passive scanning to be forced with passive_scan=1

	  configurable
	* improved P2P operating channel selection for various multi-channel

	* added mechanism to disable TLS Session Ticket extension
	  - a workaround for servers that do not support TLS extensions that
	    was enabled by default in recent OpenSSL versions
	  - tls_disable_session_ticket=1
	  - automatically disable TLS Session Ticket extension by default when
	    using EAP-TLS/PEAP/TTLS (i.e., only use it with EAP-FAST)
	* changed VENDOR-TEST EAP method to use proper private enterprise number
	  (this will not interoperate with older versions)
	* disable network block temporarily on authentication failures
	* improved WPS AP selection during WPS PIN iteration

	  interop issues with deployed station implementations that do not
	  remove active PBC indication from Probe Request frames properly
	* added basic support for 60 GHz band
	* extend EAPOL frames processing workaround for roaming cases
	  (postpone processing of unexpected EAPOL frame until association

2012-05-10 - v1.0
	* bsd: Add support for setting HT values in IFM_MMASK.
	* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
	  This allows the driver to use PS buffering of Deauthentication and
	  Disassociation frames when the STA is in power save sleep. Only
	  available with drivers that provide TX status events for Deauth/
	  Disassoc frames (nl80211).
	* Drop oldest unknown BSS table entries first. This makes it less
	  likely to hit connection issues in environments with huge number
	  of visible APs.
	* Add systemd support.
	* Add support for setting the syslog facility from the config file
	  at build time.
	* atheros: Add support for IEEE 802.11w configuration.

	  config parameter ieee80211n.
	* Allow AP mode to disconnect STAs based on low ACK condition (when
	  the data connection is not working properly, e.g., due to the STA
	  going outside the range of the AP). Disabled by default, enable by
	  config option disassoc_low_ack.
	* nl80211:
	  - Support GTK rekey offload.
	  - Support PMKSA candidate events. This adds support for RSN
	    pre-authentication with nl80211 interface and drivers that handle
	    roaming internally.
	* dbus:
	  - Add a DBus signal for EAP SM requests, emitted on the Interface
	    object.
	  - Export max scan ssids supported by the driver as MaxScanSSID.
	  - Add signal Certification for information about server certification.
	  - Add BSSExpireAge and BSSExpireCount interface properties and
	    support set/get, which allows for setting BSS cache expiration age
	    and expiration scan count.
	  - Add ConfigFile to AddInterface properties.
	  - Add Interface.Country property and support to get/set the value.
	  - Add DBus property CurrentAuthMode.
	  - P2P DBus API added.
	  - Emit property changed events (for property BSSs) when adding/
	    removing BSSs.
	  - Treat '' in SSIDs of Interface.Scan as a request for broadcast
	    scan, instead of ignoring it.
	  - Add DBus getter/setter for FastReauth.
	  - Raise PropertiesChanged on org.freedesktop.DBus.Properties.
	* wpa_cli:
	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
	    due to inactivity.

	  - Add bss_expire_age and bss_expire_count commands to set/get BSS
	    cache expiration age and expiration scan count.
	  - Add ability to set scan interval (the time in seconds wpa_s waits
	    before requesting a new scan after failing to find a suitable
	    network in scan results) using scan_interval command.
	  - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
	  - Add command get version, that returns wpa_supplicant version string.
	  - Add command sta_autoconnect for disabling automatic reconnection
	    on receiving disconnection event.
	  - Setting bssid parameter to an empty string "" or any can now be
	    used to clear the bssid_set flag in a network block, i.e., to remove
	    bssid filtering.
	  - Add tdls_testing command to add a special testing feature for
	    changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
	    enabled as well.
	  - For interworking, add wpa_cli commands interworking_select,
	    interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp.

	    debugging level and to change the log level during run time.
	  - Add note command, which can be used to insert notes to the debug
	    log.
	  - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y
	    can now be used to build wpa_cli with internal implementation of
	    line editing and history support. This can be used as a replacement
	    for CONFIG_READLINE=y.
	* AP mode: Add max_num_sta config option, which can be used to limit
	  the number of stations allowed to connect to the AP.
	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
	  config file.
	* wext: Increase scan timeout from 5 to 10 seconds.
	* Add blacklist command, allowing an external program to
	  manage the BSS blacklist and display its current contents.
	* WPS:
	  - Add wpa_cli wps_pin get command for generating random PINs. This can
	    be used in a UI to generate a PIN without starting WPS (or P2P)
	    operation.
	  - Set RF bands based on driver capabilities, instead of hardcoding
	    them.
	  - Add mechanism for indicating non-standard WPS errors.
	  - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks
	    by default.
	  - Add wps_ap_pin cli command for wpa_supplicant AP mode.
	  - Add wps_check_pin cli command for processing PIN from user input.
	    UIs can use this command to process a PIN entered by a user and to

	    Number, and Serial Number changes.
	  - Fragment size is now configurable for EAP-WSC peer. Use
	    wpa_cli set wps_fragment_size <val>.
	  - Disable AP PIN after 10 consecutive failures. Slow down attacks on
	    failures up to 10.
	  - Allow AP to start in Enrollee mode without AP PIN for probing, to
	    be compatible with Windows 7.
	  - Add Config Error into WPS-FAIL events to provide more info to the
	    user on how to resolve the issue.
	  - Label and Display config methods are not allowed to be enabled
	    at the same time, since it is unclear which PIN to use if both
	    methods are advertised.
	  - When controlling multiple interfaces:
	     - apply WPS commands to all interfaces configured to use WPS
	     - apply WPS config changes to all interfaces that use WPS
	     - when an attack is detected on any interface, disable AP PIN on
	       all interfaces
	* WPS ER:
	  - Add special AP Setup Locked mode to allow read only ER.
	    ap_setup_locked=2 can now be used to enable a special mode where
	    WPS ER can learn the current AP settings, but cannot change them.
	  - Show SetSelectedRegistrar events as ctrl_iface events
	  - Add wps_er_set_config to enroll a network based on a local
	    network configuration block instead of having to (re-)learn the
	    current AP settings with wps_er_learn.
	  - Allow AP filtering based on IP address, add ctrl_iface event for
	    learned AP settings, add wps_er_config command to configure an AP.
	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
	    for testing protocol extensibility.
	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
	    workarounds.
	  - Add support for AuthorizedMACs attribute.
	* TDLS:
	  - Propogate TDLS related nl80211 capability flags from kernel and
	    add them as driver capability flags. If the driver doesn't support
	    capabilities, assume TDLS is supported internally. When TDLS is
	    explicitly not supported, disable all user facing TDLS operations.
	  - Allow TDLS to be disabled at runtime (mostly for testing).
	    Use set tdls_disabled.
	  - Honor AP TDLS settings that prohibit/allow TDLS.
	  - Add a special testing feature for changing TDLS behavior. Use
	    CONFIG_TDLS_TESTING build param to enable. Configure at runtime
	    with tdls_testing cli command.
	  - Add support for TDLS 802.11z.
	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
	  wlantest can be used to capture frames from a monitor interface
	  for realtime capturing or from pcap files for offline analysis.
	* Interworking: Support added for 802.11u. Enable in .config with
	  CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters
	  for interworking. wpa_cli commands added to support this are
	  interworking_select, interworking_connect, anqp_get, fetch_anqp,
	  and stop_fetch_anqp.
	* Android: Add build and runtime support for Android wpa_supplicant.
	* bgscan learn: Add new bgscan that learns BSS information based on
	  previous scans, and uses that information to dynamically generate
	  the list of channels for background scans.
	* Add a new debug message level for excessive information. Use
	  -ddd to enable.
	* TLS: Add support for tls_disable_time_checks=1 in client mode.
	* Internal TLS:
	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
	    CONFIG_TLSV11.
	  - Add domainComponent parser for X.509 names.
	* Linux: Add RFKill support by adding an interface state "disabled".
	* Reorder some IEs to get closer to IEEE 802.11 standard. Move
	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
	  Move HT IEs to be later in (Re)Assoc Resp.
	* Solaris: Add support for wired 802.1X client.
	* Wi-Fi Direct support. See README-P2P for more information.
	* Many bugfixes.

2010-04-18 - v0.7.2
	* nl80211: fixed number of issues with roaming
	* avoid unnecessary roaming if multiple APs with similar signal
	  strength are present in scan results
	* add TLS client events and server probing to ease design of
	  automatic detection of EAP parameters
	* add option for server certificate matching (SHA256 hash of the
	  certificate) instead of trusted CA certificate configuration
	* bsd: Cleaned up driver wrapper and added various low-level
	  configuration options
	* wpa_gui-qt4: do not show too frequent WPS AP available events as
	  tray messages
	* TNC: fixed issues with fragmentation
	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
	  interoperate with other implementations; may potentially breaks
	  compatibility with older wpa_supplicant/hostapd versions)
	* wpa_cli: added option for using a separate process to receive event
	  messages to reduce latency in showing these
	  (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
	* maximum BSS table size can now be configured (bss_max_count)
	* BSSes to be included in the BSS table can be filtered based on
	  configured SSIDs to save memory (filter_ssids)
	* fix number of issues with IEEE 802.11r/FT; this version is not
	  backwards compatible with old versions
	* nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
	  and over-the-DS)
	* add freq_list network configuration parameter to allow the AP
	  selection to filter out entries based on the operating channel
	* add signal strength change events for bgscan; this allows more
	  dynamic changes to background scanning interval based on changes in
	  the signal strength with the current AP; this improves roaming within
	  ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
	  configuration block to request background scans less frequently when
	  signal strength remains good and to automatically trigger background
	  scans whenever signal strength drops noticeably
	  (this is currently only available with nl80211)
	* add BSSID and reason code (if available) to disconnect event messages
	* wpa_gui-qt4: more complete support for translating the GUI with
	  linguist and add German translation
	* fix DH padding with internal crypto code (mainly, for WPS)
	* do not trigger initial scan automatically anymore if there are no
	  enabled networks

2010-01-16 - v0.7.1
	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
	  is not fully backwards compatible, so out-of-tree driver wrappers
	  will need modifications
	* cleaned up various module interfaces
	* merge hostapd and wpa_supplicant developers' documentation into a
	  single document
	* nl80211: use explicit deauthentication to clear cfg80211 state to
	  avoid issues when roaming between APs
	* dbus: major design changes in the new D-Bus API
	  (fi.w1.wpa_supplicant1)
	* nl80211: added support for IBSS networks
	* added internal debugging mechanism with backtrace support and memory
	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
	* added WPS ER unsubscription command to more cleanly unregister from
	  receiving UPnP events when ER is terminated
	* cleaned up AP mode operations to avoid need for virtual driver_ops
	  wrapper
	* added BSS table to maintain more complete scan result information
	  over multiple scans (that may include only partial results)
	* wpa_gui-qt4: update Peers dialog information more dynamically while
	  the dialog is kept open
	* fixed PKCS#12 use with OpenSSL 1.0.0
	* driver_wext: Added cfg80211-specific optimization to avoid some
	  unnecessary scans and to speed up association

2009-11-21 - v0.7.0
	* increased wpa_cli ping interval to 5 seconds and made this
	  configurable with a new command line options (-G<seconds>)
	* fixed scan buffer processing with WEXT to handle up to 65535
	  byte result buffer (previously, limited to 32768 bytes)
	* allow multiple driver wrappers to be specified on command line
	  (e.g., -Dnl80211,wext); the first one that is able to initialize the
	  interface will be used
	* added support for multiple SSIDs per scan request to optimize
	  scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
	  SSIDs); this requires driver support and can currently be used only
	  with nl80211
	* added support for WPS USBA out-of-band mechanism with USB Flash
	  Drives (UFD) (CONFIG_WPS_UFD=y)
	* driver_ndis: add PAE group address to the multicast address list to
	  fix wired IEEE 802.1X authentication
	* fixed IEEE 802.11r key derivation function to match with the standard
	  (note: this breaks interoperability with previous version) [Bug 303]
	* added better support for drivers that allow separate authentication
	  and association commands (e.g., mac80211-based Linux drivers with
	  nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
	  to be used (IEEE 802.11r)
	* fixed SHA-256 based key derivation function to match with the
	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
	  (note: this breaks interoperability with previous version) [Bug 307]
	* use shared driver wrapper files with hostapd
	* added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
	  block; this can be used for open and WPA2-Personal networks
	  (optionally, with WPS); this links in parts of hostapd functionality
	  into wpa_supplicant
	* wpa_gui-qt4: added new Peers dialog to show information about peers
	  (other devices, including APs and stations, etc. in the neighborhood)
	* added support for WPS External Registrar functionality (configure APs
	  and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
	  and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
	  wps_er_pbc, wps_er_learn
	  (this can also be used with a new 'none' driver wrapper if no
	  wireless device or IEEE 802.1X on wired is needed)
	* driver_nl80211: multiple updates to provide support for new Linux
	  nl80211/mac80211 functionality
	* updated management frame protection to use IEEE Std 802.11w-2009
	* fixed number of small WPS issues and added workarounds to
	  interoperate with common deployed broken implementations
	* added support for NFC out-of-band mechanism with WPS
	* driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
	  address frames
	* added preliminary support for IEEE 802.11r RIC processing
	* added support for specifying subset of enabled frequencies to scan
	  (scan_freq option in the network configuration block); this can speed
	  up scanning process considerably if it is known that only a small
	  subset of channels is actually used in the network (this is currently
	  supported only with -Dnl80211)
	* added a workaround for race condition between receiving the
	  association event and the following EAPOL-Key
	* added background scan and roaming infrastructure to allow
	  network-specific optimizations to be used to improve roaming within
	  an ESS (same SSID)
	* added new DBus interface (fi.w1.wpa_supplicant1)

2009-01-06 - v0.6.7
	* added support for Wi-Fi Protected Setup (WPS)
	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
	  enroll credentials for a network using PIN and PBC methods; in
	  addition, wpa_supplicant can act as a wireless WPS Registrar to
	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
	  into .config and setting the runtime configuration variables in
	  wpa_supplicant.conf (see WPS section in the example configuration
	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
	  manage WPS negotiation; see README-WPS for more details
	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
	* added support for using driver_test over UDP socket
	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
	  2008 NPS; optional cryptobinding is now enabled (again) by default
	* fixed PSK editing in wpa_gui
	* changed EAP-GPSK to use the IANA assigned EAP method type 51
	* added a Windows installer that includes WinPcap and all the needed
	  DLLs; in addition, it set up the registry automatically so that user
	  will only need start wpa_gui to get prompted to start the wpasvc
	  servide and add a new interface if needed through wpa_gui dialog
	* updated management frame protection to use IEEE 802.11w/D7.0

2008-11-23 - v0.6.6
	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
	  (can be used to simulate test SIM/USIM card with a known private key;
	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
	* added a new network configuration option, wpa_ptk_rekey, that can be
	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
	  against TKIP deficiencies
	* added an optional mitigation mechanism for certain attacks against
	  TKIP by delaying Michael MIC error reports by a random amount of time
	  between 0 and 60 seconds; this can be enabled with a build option
	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
	  not bytes
	* updated OpenSSL code for EAP-FAST to use an updated version of the
	  session ticket overriding API that was included into the upstream
	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
	  needed with that version anymore)
	* updated userspace MLME instructions to match with the current Linux
	  mac80211 implementation; please also note that this can only be used
	  with driver_nl80211.c (the old code from driver_wext.c was removed)
	* added support (Linux only) for RoboSwitch chipsets (often found in
	  consumer grade routers); driver interface 'roboswitch'
	* fixed canceling of PMKSA caching when using drivers that generate
	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
	  about

2008-11-01 - v0.6.5
	* added support for SHA-256 as X.509 certificate digest when using the
	  internal X.509/TLSv1 implementation
	* updated management frame protection to use IEEE 802.11w/D6.0
	* added support for using SHA256-based stronger key derivation for WPA2
	  (IEEE 802.11w)
	* fixed FT (IEEE 802.11r) authentication after a failed association to
	  use correct FTIE
	* added support for configuring Phase 2 (inner/tunneled) authentication
	  method with wpa_gui-qt4

2008-08-10 - v0.6.4
	* added support for EAP Sequences in EAP-FAST Phase 2
	* added support for using TNC with EAP-FAST
	* added driver_ps3 for the PS3 Linux wireless driver
	* added support for optional cryptobinding with PEAPv0
	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
	  allow fallback to full handshake if server rejects PAC-Opaque
	* added fragmentation support for EAP-TNC
	* added support for parsing PKCS #8 formatted private keys into the
	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
	  encapsulated RSA key can now be used)
	* added option of using faster, but larger, routines in the internal
	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
	* fixed race condition between disassociation event and group key
	  handshake to avoid getting stuck in incorrect state [Bug 261]
	* fixed opportunistic key caching (proactive_key_caching)

2008-02-22 - v0.6.3
	* removed 'nai' and 'eappsk' network configuration variables that were
	  previously used for configuring user identity and key for EAP-PSK,
	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
	  replacement for 'nai' (if old configuration used a separate
	  'identity' value, that would now be configured as
	  'anonymous_identity'). 'password' field is now used as the
	  replacement for 'eappsk' (it can also be set using hexstring to
	  present random binary data)
	* removed '-w' command line parameter (wait for interface to be added,
	  if needed); cleaner way of handling this functionality is to use an
	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
	  when an interface is added
	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
	  indicating when new scan results become available
