crl handling

As far as I know freeradius uses openssl to handle crls. openssl also has an option -use_deltas to enable support for delta CRLs. Is this option available in freeradius? According to eap.conf it is necessary to restart radiusd if a new version of a crl is published. Are there plans to enable reading of a new crl without restarting the server? Thanks Norbert Wegener
