+## YesSQL breaking changes
+
+YesSql is now using the new SQL client which encrypts the connection by default.
+
+If the SQL Server does not have a trusted SSL certificate and you would and want to continue using encrypted communicated using the untrusted server, add `TrustServerCertificate=True` to the connection string.
+
+If you do not want to encrypt the communication at all, you can use `Encrypt=false`.
