md5sum --check now supports the -r format from the corresponding BSD tool.
This also affects sha1sum, sha224sum, sha384sum and sha512sum.
+ pwd now works also on systems without openat. On such systems, pwd
+ would fail when run from a directory whose absolute name contained
+ more than PATH_MAX / 3 components. Also affected due to their use
+ of canonicalize_* functions: df, stat, readlink.
+
+** Changes in behavior
+
+ timeout now only processes the first signal received from the set
+ it is handling (SIGTERM, SIGINT, ...). This is to support systems that
+ implicitly create threads for some timer functions (like GNU/kFreeBSD).

* Noteworthy changes in release 8.13 (2011-09-08) [stable]
