Werk 13474 introduced the monitoring of agent plugins and local checks via a dedicated check plugin (checkkmk_agent_plugins). This has been reworked and extended in multiple ways:

The functionality has been integrated into the plugin checkmk_agent (service "Check_MK Agent"). The corresponding configuration options have been integrated into the ruleset "Checkmk Agent installation auditing".
Users can now configure separate version requirements for agent plugins and local checks. Analogously, users can now configure two separate exclusion patterns.
In case minimum versions are configured, users can also configure the monitoring state for unparsable versions. Previously, Checkmk always reported UNKNOWN in this case.
Checkmk now additionally checks for duplicate agent plugins and local checks (separately). In case duplicate files are found, Checkmk reports WARN. This check respects any user-defined exclusion patterns.
