Salesforce TLS 1.0 Deprecation
On July 22 2017, Salesforce began to remove TLS (Transport Layer Security) 1.0 support. This means all connections to Salesforce must be made from a client application or connector that supports TLS 1.1 or higher. Otherwise, the connection will fail.
All recent versions of our Salesforce.com ODBC Driver support TLS 1.1+, so no action should be required as a result of Salesforce's decision to deprecate TLS 1.1.
