+* Deprecated distribution formats:
+
+ - The 'shar' and 'compress' distribution formats are deprecated, and
+ scheduled for removal in Automake 2.0. Accordingly, the use of the
+ 'dist-shar' and 'dist-tarZ' will cause warnings at automake runtime
+ (in the 'obsolete' category), and the recipes for the Automake-generated
+ targets 'dist-shar' and 'dist-tarZ' will unconditionally display
+ (non-fatal) warnings at make runtime.
+
+* New configure runtime warnings about "rm -f" support:
+
+ - To simplify transition to Automake 2.0, the shell code expanded by
+ AM_INIT_AUTOMAKE now checks (at configure runtime) that the default
+ 'rm' program in PATH doesn't complain when called without any
+ non-option argument if the '-f' option is given (so that commands
+ like "rm -f" and "rm -rf" act as a no-op, instead of raising usage
+ error). If this is not the case,
+ the configure script is aborted, to call the attention of the user
+ on the issue, and invite him to fix his PATH. The checked 'rm'
+ behavior is very widespread in the wild, and will be required by
+ future POSIX version:
+
+ <http://austingroupbugs.net/view.php?id=542>
+
+ The user can still force the configure process to complete even in the
+ presence of a broken 'rm' by defining the ACCEPT_INFERIOR_RM_PROGRAM
+ environment variable to "yes". And the generated Makefiles should
+ still work correctly even when such broken 'rm' is used. But note
+ that this will no longer be the case with Automake 2.0 though, so, if
+ you encounter the warning, please report it to us ASAP (and try to fix
+ your environment as well).

+New in 1.13.4:
+
+* Bugs fixed:
+
+ - Fix a minor regression introduced in Automake 1.13.3: when two or more
+ user-defined suffix rules were present in a single Makefile.am,
+ automake would needlessly include definition of some make variables
+ related to C compilation in the generated Makefile.in (bug#14560).
