 changes relative to sbcl-1.1.8:
+  * new feature: the contrib SB-GMP links with libgmp at runtime to speed
+    up arithmetic on bignums and ratios.  (contributed by Stephan Frank)
   * enhancement: disassemble now annotates some previously missing static
     functions, like LENGTH.
   * enhancement: clean.sh now also cleans doc/internals.
+  * enhancement: SB-EXT:PRINT-SYMBOL-WITH-PREFIX can be used within ~// to
+    print a symbol with a package prefix.
+  * enhancement: The debugger and backtracing are more robust against buggy
+    PRINT-OBJECT methods.
   * optimization: calls to static functions on x86-64 use less instructions.
   * optimization: compute encode-universal-time at compile time when possible.
   * optimization: when referencing internal functions as #'x, don't go through
