Yeah, I saw there was mention of…
Changes since 2.4.2 (to 2.5.0)
Breaking change
SSL/TLS API (BearSSL)
… in the release notes, but that would mean espressif8266@>2.0.0 would have those changes… so I don’t know what was the cause of that change to the API.
Anyway, obviously it’s working for you now!
