+* New feature: "::=" simple assignment operator as defined by POSIX in 2012.
+  This operator has identical functionality to ":=" in GNU make, but will be
+  portable to any implementation of make conforming to a sufficiently new
+  version of POSIX (see http://austingroupbugs.net/view.php?id=330).  It is
+  not necessary to define the .POSIX target to access this operator.

 * New feature: GNU Guile integration
   This version of GNU make can be compiled with GNU Guile integration.
   GNU Guile serves as an embedded extension language for make.
