Upgrading

Backwards compatibility with driver version 2.7.0–2.10.x

Because certificate revocation checking is now enabled by default, an
application that is unable to contact the OCSP endpoints and/or CRL
distribution points specified in a server’s certificate may experience
connectivity issues (e.g. if the application is behind a firewall with
an outbound whitelist). This is because the driver needs to contact
the OCSP endpoints and/or CRL distribution points specified in the
server’s certificate and if these OCSP endpoints and/or CRL
distribution points are not accessible, then the connection to the
server may fail. In such a scenario, connectivity may be able to be
restored by disabling certificate revocation checking by adding
tlsDisableCertificateRevocationCheck=true to the application’s connection
string.
