@ -8,6 +8,10 @@ ChangeLog for wpa_supplicant
* 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
2009-01-06 - v0.6.7
* added support for Wi-Fi Protected Setup (WPS)
