Has it changed? > Nope, you're right. wpa_supplicant.conf(5) calls it out clearly: scan_ssid SSID scan technique; 0 (default) or 1. Technique 0 scans for the SSID using a broadcast Probe Request frame while 1 uses a directed Probe Request frame. Access points that cloak them- selves by not broadcasting their SSID require technique 1, but beware that this scheme can cause scanning to take longer to com- plete. though obviously you need to know to look there.
