v2.1.0 * Only sign the referenced element when passed reference_uri (thanks
to @soby).

  possible to pass a common name that will be matched against the CN
  of a cert trusted by the CA store.

• Order-agnostic cert chain validation and friendlier ingestion of
  cert chains.

• Minor/internal changes

  v4.0.0 - Replace PyOpenSSL with Cryptography (#260)

  • This is a major infrastructure change that replaces core
    certificate parsing, key processing, signature validation, and
    certificate chain validation functions previously provided by
    PyOpenSSL with those provided by Cryptography. Care was taken to
    preserve the exisitng API, including exception types, but many
    error messages raised in various error conditions have changed. If
    you see unexpected behavior and you have reason to believe it is
    incorrect, please file an issue.

  • Breaking change: the ca_path parameter, previously used to specify
    CA certificate stores, is no longer supported. Use the ca_pem_file
    parameter instead.

• Raise error when invalid certificate string is passed as input to signer

• Fix public key matching for ECDSA (#245)
