- Update to 19.1.0
  * Basic implementation of ``ldaptor.protocols.pureldap.LDAPSearchResultReference``.
  * Explicit ``ldaptor.protocols.ldap.ldaperrors`` classes declaration was made
    to allow syntax highlighting for this module.

    on server initialization.

    ``userIdentity``, ``oldPasswd`` and ``newPasswd`` attributes. Password attributes are represented as asterisks.
  * ``ldaptor.protocols.pureldap.LDAPBindRequest`` string representation is now using asterisks to represent
    ``auth`` attribute.
  * ``NotImplementedError`` for ``ldaptor.protocols.pureldap.LDAPSearchResultReference`` was fixed.
  * StartTLS regression bug was fixed: ``ldaptor.protocols.pureldap.LDAPStartTLSRequest.oid`` and
    ``ldaptor.protocols.pureldap.LDAPStartTLSResponse.oid`` must be of bytes type.
  * replace direct dependency on pyOpenSSL with Twisted[tls]
