For the Nagios core, immediately after config generation, all but the latest config serial were deleted. This could lead to race conditions.
To prevent this, the two most recent config serials are retained.
This improvement enhances the stability and reliability of Nagios configuration handling. Users do not need to take any manual action to benefit from this change.
