+Differences from 2.0 Perl API:
+
+- Perl 5.6 is supported
+
+- backend methods return actual LDAP result codes, not
+ true/false; this gives the Perl module finer control
+ of the error returned to the client
+
+- a filterSearchResults configuration file directive was
+ added to tell the backend glue that the results returned
+ from the Perl module are candidates only
+
+- the "init" method is called after the backend has been
+ initialized - this lets you do some initialization after
+ *all* configuration file directives have been read
+
+- the interface for the search method is improved to
+ pass the scope, dereferencing policy, size limit, etc.
+ See SampleLDAP.pm for details.
+
+These changes were sponsored by myinternet Limited.
