+Wednesday  November 28, 2012 guy@alum.mit.edu.
+  Summary for 4.3.1 tcpdump release
+	Print "LLDP, length N" for LLDP packets even when not in verbose
+	    mode, so something is printed even if only the timestamp is
+	    present
+	Document "-T carp"
+	Print NTP poll interval correctly (it's an exponent, so print
+	    both its raw value and 2^value)
+	Document that "-e" is used to get MAC addresses
+	More clearly document that you need to escape or quote
+	    backslashes in filter expressions on the command line
+	Fix some "the the" in the man page
+	Use the right maximum path length
+	Don't treat 192_1_2, when passed to -i, as an interface number
