 * Bug fixes.
 * Improved `make check' running more tests.
-* Tuned algorithm cutoff points for many machines.
+* Tuned algorithm cutoff points for many machines.  This will improve speed for
+  a lot of operations, in some cases by a large amount.
 * Major speed improvments: Alpha 21264.
 * Some speed improvments: Cray vector computers, AMD K6 and Athlon, Intel P5
   and P-Pro/II/III.
 * The mpf_get_prec function now works as it did in GMP 2.
 * New utilities for auto-tuning and speed measuring.
-* Multiplication now optionally uses FFT for very large operands.
-* Support for new systems: Solaris running on x86, FreeBSD 5,
-  HP-UX 11, Cray vector computers, Rhapsody, Nextstep/Openstep.
