13.5.2. What's new in the syslog-ng pattern database format V5
The V5 database format has the following differences compared to the V4 format:
The <ruleset> element can now store multiple reference URLs using the new <rule_urls> element. For details, see Section 126.96.36.199, Element: ruleset.
In an <action>, you can now initialize a new context. As a result, the <message> element is not required. For details, see Section 188.8.131.52, Element: create-context.
inherit-propertiesattribute is deprecated, use the
inherit-modeattribute instead. For details, see Section 184.108.40.206, Element: action.
