v0.65.0

Fixed

• Breaking: a password-protected PDF fails with EncryptedDocumentException and
  [extraction_failure_reason=encrypted_document], as a password-protected Office file does. It was a
  DocumentProcessingException carrying only the Unpdf diagnostic [extraction_error_kind=Encrypted], so a consumer that
  maps the failure reason showed the raw message for every encrypted PDF. Other Unpdf failures are unchanged. Migration:
  catch EncryptedDocumentException (or read the failure reason) where you matched the error kind.
