To know about .contents.panic file for diagnostics

Kernel panics are reported in "/Library/Logs/DiagnosticReports" with name .panic In Catalina and above OS I have seen hidden files .contents.panic.

When kernel panic is generated .panic is created and this hidden file (.contents.panic) also gets modified . It always points to the latest panic. What is the purpose of this separate hidden file? What is the difference between this and .panic file in terms of crashes reporting?
