+# This is a pre-5.0 snapshot taken from mainline.  It includes the CVE
+# fixes in v4.10 and v4.11.
+#
+# The version number 4.9 in the below is topologically correct.  It is
+# the point where the v4.x maintenance branch was created (both v4.10
+# and v4.11 were drawn from that branch).
+#
+# If this were Fedora I'd be using something like libreswan-v4.9~1324
+# (that's a tilda).  Perhaps 4.11nb5.1324 would be better?
