The value until was previously only used in Z39.50 Init negotiation and, later, in a session controlled sizes of records returned. This is controlled using -k option. It can be specified, per server, with element maximumrecordsize in YAZ' GFS XML config. --- diff --git a/NEWS b/NEWS index 536f12a..200dfc4 100644 --- a/NEWS +++ b/NEWS @@ -1,3 +1,9 @@ +For the generic frontend server, the maximum record size is used as maximum +size of incoming packages (SRU + Z39.50).
