TLDR: we import WifiSecureClient.h and used to have access to the WiFi class too, now we don't since switching alpha3 to RC1.

@valeros is this a regression, or just a newer way to use it? Are there any docs that mention the change? |

There will be docs. Reason is that WiFiClientSecure can now work on chips without WiFi, so it is not included by default. The whole network interface layer has changed to support H2 (and P4) and to also equalize all network interfaces (with PPP also on the way) |
