### [0.9.4] May 5, 2018.
- Supports AutoConnectConfig::autoReconnect option, it will scan the WLAN when it can not connect to the default SSID, apply the applicable credentials if it is saved, and try reconnecting.
<p>Registering the "not found" handler is a different way than ESP8266WebServer. The <em>onNotFound</em> of ESP8266WebServer does not work with AutoConnect. AutoConnect overrides <em>ESP8266WebServer::onNotFound</em> to handle a captive portal.

<p>When the captive portal is started, SoftAP starts and the STA is disconnected. The current SSID setting memorized in ESP8266 will be lost.<br/>
If the <ahref="../api/index.html#autoreconnect"><strong>autoReconnect</strong></a> option of the <ahref="../api/index.html#autoconnectconfig-api"><strong>AutoConnectConfig</strong></a> class is enabled, it automatically attempts to reconnect to the disconnected past access point. When the autoReconnect option is specified, AutoConnect will not start SoftAP immediately if the first WiFi.begin fails. It will scan WiFi signal and the same connection information as the detected BSSID is stored in EEPROM as AutoConnect's credentials, explicitly apply it with WiFi.begin and rerun.</p>

```arduino hl_lines="3"

An autoReconnect option is available to *AutoConnect::begin* without SSID and pass passphrase.

#### autoReconnect
Automatically reconnect to past established access point (BSSID) when the current configured SSID in ESP8266 could not be connected. By enabling this option, *AutoConnect::begin()* function will attempt to reconnect to a known access point using credentials stored in the EEPROM, even if the connection failed by current SSID.

When the autoReconnect option is enabled, an automatic connection will behave if the following conditions are satisfied.
- Invokes *AutoConnect::begin* without user name and password parameter as ```begin()```.
- If one of the saved BSSIDs (not the SSID) of the credentials matches the BSSID detected by the network scan.
