We are using libreswan 3.25 bundled with centos 7.9, having a tunnel with
Cisco ASA with DPD enabled. Occasionally, the tunnel stops working, and a
manual restart of libreswan will always be able to fix it.

We are thinking of upgrading to the latest 4.5 from
https://download.libreswan.org/binaries/rhel/7/x86_64/ and see if it is
more stable. Is 4.5 a simple drop-in upgrade to 3.25 if we do rpm -U?
