+	Also add NEWS about the error check for explicit and pattern

+
+* WARNING: Backward-incompatibility!
+  In previous versions of make it was acceptable to list one or more explicit
+  targets followed by one or more pattern targets in the same rule and it
+  worked "as expected".  However, this was not documented as acceptable and if
+  you listed any explicit targets AFTER the pattern targets, the entire rule
+  would be mis-parsed.  This release removes this ability completely: make
+  will generate an error message if you mix explicit and pattern targets in
+  the same rule.
+
+* WARNING: Backward-incompatibility!
   As a result of parser enhancements, three backward-compatibility issues
   exist: first, a prerequisite containing an "=" cannot be escaped with a
   backslash any longer.  You must create a variable containing an "=" and
