 2022-02-14: added option "Report safe files" (--report-patch)
 2022-02-24: removed deployment of the logpresso executable -> separate package log4j_executable.mkp
 
+Note: As there was an issue with large ( >20MB) agent plugins and the cmk agent installer for Windows, 
+      you need to update your CMK system to CMK 2.0.0p21 or newer to use this plugin.
+
 IMPORTANT: If you update from a previous version, you need first to uninstall the cve_2021_44228_log4j package. 
            Then install the new cve_2021_44228_log4j package and the log4j_executables-2020305.v3.0.1.mkp package.
