+Monday March 18, 2013 guy@alum.mit.edu
+Summary for 1.4.0 libpcap release
+	Add netfilter/nfqueue interface.
+	If we don't have support for IPv6 address resolution, support,
+	    in filter expressions, what IPv6 stuff we can.
+	Checks added for malloc()/realloc()/etc. failures.
+	Fix pcap-config to include -lpthread if canusb support is
+	    present
+	Try to fix "pcap_parse not defined" problems when --without-flex
+	    and --without-bison are used when you have Flex and Bison
+	Fix some issues with the pcap_loop man page.
+	Fix pcap_getnonblock() and pcap_setnonblock() to fill in the
+	    supplied error message buffer
+	Fix typo that, it appeared, would cause pcap-libdlpi.c not to
+	    compile (perhaps systems with libdlpi also have BPF and use
+	    that instead)
+	Catch attempts to call pcap_compile() on a non-activated pcap_t
+	Fix crash on Linux with CAN-USB support without usbfs
+	Fix addition of VLAN tags for Linux cooked captures
+	Check for both EOPNOTSUPP and EINVAL after SIOCETHTOOL ioctl, so
+	    that the driver can report either one if it doesn't support
+	    SIOCETHTOOL
+	Add DLT_INFINIBAND and DLT_SCTP
+	Describe "proto XXX" and "protochain XXX" in the pcap-filter man
+	    page
+	Handle either directories, or symlinks to directories, that
+	    correspond to interfaces in /sys/class/net
+	Fix handling of VLAN tag insertion to check, on Linux 3.x
+	    kernels, for VLAN tag valid flag
+	Clean up some man pages
+	Support libnl3 as well as libnl1 and libnl2 on Linux
+
