 * WARNING: Backward-incompatibility!
+  GNU make now uses temporary files in more situations than previous releases.
+  If your build system sets TMPDIR (or TMP or TEMP on Windows) and deletes the
+  contents during the build, or uses restrictive permissions, this may cause
+  problems.  You can choose an alternative temporary directory only for use by
+  GNU make by setting the new MAKE_TMPDIR environment variable.  Note that
+  this value CANNOT be set inside the makefile, since make needs to find its
+  temporary directory before the makefiles are parsed.
+
+* WARNING: Backward-incompatibility!
+  Previously each target in a grouped target rule (pattern or explicit) was
+  considered individually: if the targets needed by the build were not out of
+  date the recipe was not run even if other targets in the group were out of
+  date.  Now if any of the grouped targets are needed by the build, then if
+  any of the grouped targets are out of date the recipe is run and all targets
+  in the group are considered updated.

   Previously if --no-print-directory was seen anywhere in the environment or
   command line it would take precedence over any --print-directory.  Now, the

-* New feature: The MAKE_TMPDIR environment variable
-  If you prefer that GNU make place temporary files in a different directory
-  than the standard TMPDIR (or TMP or TEMP on Windows), set the MAKE_TMPDIR
-  environment variable before starting make (this value CANNOT be set inside
-  the makefile, since make needs to find its temporary directory before the
-  makefiles are parsed).  This is useful for build systems which reset TMPDIR
-  and clean it out during the build process.
