 * Upgrade from GPL version 2 to GPL version 3 or later.
+* A number of portability improvements inherited from gnulib.
+* Avoid undefined behavior introduced in 1.4.9b in the `format' builtin
+  when handling %c.  However, this area of code has never been documented,
+  and currently does not match the POSIX behavior of printf(1), so it may

 * The `format' builtin now understands formats such as %a, %A, and %'hhd,
   and works around a number of platform printf bugs.  Furthermore, the

 * The testsuite is improved to also run gnulib portability tests for the
   features that M4 imports from gnulib.
