Thanks@piervalli Interesting!
As Qt 5 binaries by default use openssl and not TLS, this should not have any impact on Qt 5.15. That is, unless you configured Qt yourself and explicitly added -schannel.
For Qt 6.2 onwards, Qt is by default built both with OpenSSL and schannel support. Anyhow, Qt doesn't hardcode any ciphers on it's own, but relies on the system defaults. So this should be only a problem if you're relying on schannel to connect to a server that doesn't support anything but TLS 1.0 or TLS 1.1, or have hardcoded your app to use TLS 1.0 or TLS 1.1 (for instance by calling QSslConfiguration::setProtocol()).
