Prior to this Werk the symmetric encryption of agent data (if configured) would fail silently if the option "Run agent as non-root user (Linux)" was also set, since these two options are not compatible. As a result, agent output would be sent unencrypted.
If symmetric encryption is configured, but failing, the agent will now abort immediately and transmit a message about the failure as the only output.
This will then be reported at the Check_MK Agent service of the host, alongside a CRIT status.
