v2.1

The functionality of the old -CertificateThumbprint parameters has been rolled into the newer -Certificate parameters; you can either pass in X509Certificate2 objects or thumbprints to -Certificate and it will just work. In addition, you can also pass in paths to certificates in the PowerShell Cert:\ drive, or paths to certificate files on disk.

The old Thumbprint parameters still exist for now, but they are deprecated and will produce warnings if used. They will be removed in a future release.
