The Libreswan Project has released libreswan 4.5

This is a bugfix release. The Labeled IPsec for IKEv2 now uses 1 set of
SPD policies for all sets of SPD states. Libreswan now supports RFC 6023
(Childless SA) which is required for auto=start with Labeled IPsec when
the kernel ACQUIRE is not yet present and also to continue the negotiation
when the first subnet configured mismatches or is childless. The IKE SA
is now no longer destroyed when a Child SA is mismatched, ensuring that
all but the misconfigured subnets in a left/rightsubnets= line will come
up. Initial Contact has been enabled by default, and will ensure that
a replaced IKE/IPsec SA is done more quickly and will not take 60s for
retransmit timeouts to take out the old Child SA. Previously, during
this 60s, all traffic was dropped because it was using the old state's
encryption key.
