[syslog-ng] Breaking changes between versions

I need to go from 3.31.2 to 3.37.1. Should I expect any breaking changes? Also, Redhat Insights is reporting that syslog-ng and syslog-ng-logrotate are signed with SHA1, are the newer packages signed with SHA2? Red Hat recommends that you adopt any of the options below: * Contact vendors of the packages to ask for new builds signed with supported signatures and re-install the new packages, * Resign packages with your own SHA-2 key or completely remove packages until a new build with SHA-2 signature is available from the 3rd-party vendor Thanks, Mark
