+Changes between GMP version 5.0.3 and 5.0.4
+
+ BUGS FIXED
+ * Thresholds in powm_sec for a non-fat build are now used safely, plugging a
+ one-word buffer overrun introduced in the 5.0.3 release. (We have not been
+ able to provoke malign stack smashing in any of the ~100 configurations
+ explored by the GMP nightly builds.
+
+ * Thresholds in powm_sec for a fat build are now used safely, plugging a
+ potential multi-word buffer overrun. (The bug is not fully analysed; we
+ have not been able to provoke malign stack smashing in any of the ~100
+ configurations explored by the GMP nightly builds.)
+
+ * A bug in multiplication code causing incorrect computation with extremely
+ low probability in 32-bits builds was fixed.
+
+ SPEEDUPS
+ * None.
+
+ FEATURES
+ * Some more tests added to the self-check suite.
+
+ * The AMD "Bulldozer" CPU is now recognised.
+
+ MISC
+ * None.
