+
+       Add a command 'shuf', and modify shred and sort to use the new
+       random number generator library of 'shuf'.
+
+       * AUTHORS: Add shuf.
+       * README: Likewise.
+       * NEWS: Likewise.  Mention new --random-source option for shred
+       and sort.  Move "sort +1 -2" notice to the appropriate section,
+       and clarify its role with respect to POSIXLY_CORRECT.
+       * man/.cvsignore: Add shuf.1.
+       * man/Makefile.am (dist_man_MANS): Add shuf.1.
+       (shuf.1): New dependency.
+       * man/shuf.x: New file.
+       * src/Makefile.am (bin_PROGRAMS): Add shuf.
+       (EXTRA_DIST): Remove rand-isaac.c.
+       (shuf_LDADD): New macro.
+       * src/rand-isaac.c: Remove, moving most of its contents to
+       lib/rand-isaac.c.
+       * src/shuf.c: New file.
+       * src/shred.c: Use new random-number interface rather than rand-isaac.c.
+       Don't include rand-isaac.c; include randint.h and randread.h instead.
+       (RANDOM_SOURCE_OPTION): New enum.
+       (long_opts, usage, main): New option --random-source.
+       * src/sort.c: Likewise.
+       * src/shred.c (struct irand_state, irand_init, irand32, irand_mod): Remove.
+       All callers changed to use randint interface.
+       (fillrand): Remove.  All callers changed to use randread interface.
+       (dopass): Remove dependency on ISAAC buffer size.
+       (genpattern): Don't wipe the random state here.
+       (randint_source): New static var.
+       (clear_random_data): New function.
+       (main): Allocate random source, and arrange to wipe it on exit.
+       * src/sort.c: Include md5.h, randread.h, xmemxfrm.h.
+       (longopts, usage, main): Remove undocumented --seed option;
+       it's now replaced by --random-source.
+       (rand_state, get_hash): Remove.
+       (randread_source): New static var.
+       (random_state, cmp_hashes, compare_random): New functions; they guarantee
+       no collisions in the random hash function.
+       (keycompare): Use compare_random for -R; don't fall back on comparing
+       via memcoll, since compare_random does the right thing.
+       * tests/misc/Makefile.am (TESTS): Add shuf.
+       * tests/misc/shuf: New file.
