+Breaking change in v2.1.0.0: The default behavior for SSL certificate validation when connecting to identity providers has changed. In versions before 2.1.0.0, SSL validation was disabled by default. Starting in v2.1.0.0, SSL validation is enabled by default for all IdP connections. The driver also enforces TLS 1.2 as the minimum TLS version. If you use a local identity provider without a valid SSL certificate (for testing purposes only), set `SSL_Insecure=1` in your connection string.
