 * Bugs fixed:
 
+  - The expansion of AM_INIT_AUTOMAKE ends once again with a trailing
+    newline (bug#16841).  Regression introduced in Automake 1.14.
+
   - The user can now extend the special .PRECIOUS target, the same way
     he could already do with the .MAKE .and .PHONY targets.
 
   - Fixed confusing typos in the manual and in some warning messages
     (automake bug#16827 and bug#16997).
 
-  - We no longer risk to use '$ac_aux_dir' before it's defined.  See
