[syslog-ng] the match() filter without the use of the value() option is deprecated

Can anyone shed light on what the the the below error message means? I cannot find anything on what value() is and why my syntax is wrong. I am migrating a older configuration to 3.0.4. WARNING: the match() filter without the use of the value() option is deprecated and hinders performance, please update your configuration; -- -------------------------------------------------- Jeremy M.
