Release Notes: This major release contains several updates and fixes. It introduces the new feature "z1-ldapinterface", which provides an LDAP interface to Z1 Backbone CertServer. The interface works as a separate process and provides a fully featured LDAP service, which delegates all requests for X.509 certificates and OpenPGP keys to the CertServer. The Certificate Search page has been improved. Now the filter is split into a simple and an advanced filter.
