     * Micro-optimize KERNEL:DOUBLE-FLOAT-BITS for x86/sse2.
     * Add micro-optimization for unary FTRUNCATE for x86/sse2.
     * Compiler can derive the types of the results of DECODE-FLOAT.
+    * Main disassembly routines in the DISASSEMBLE package accept 
+      :BASE, :CASE, and :RADIX keyword arguments, like
+      DISASSEMBLE:DISASSEMBLE.
+    * Micro optimizations for sse2 to allow descriptor regs for many
+      operations so that the operands can be in memory instead of a
+      register, thereby removing a register load instruction.
+    * Support for darwin/ppc 10.5 and gcc 4.8.
+    * Micro-optimization:  (expt -1 power) just returns -1 or 1
+      without actually computing the power.
 
   * ANSI compliance fixes:
+    * The values on the branch cuts for the inverse trig and
+      hyperbolic functions have been updated.  Instead of following
+      the text in the CLHS, the values are defined according to the
+      definitions in the formulas.  In particular (atanh x) for x real
+      and on the branch cut is now continuous with different
+      quadrants.  This differs from the description of the branch cut
+      for atanh in the CLHS.
 
   * Bugfixes:
-
+    * Fix error in pi reduction on x87.  It was not noticed previously
+      because the returned values were not used optimally.
+    * Better error message for empty cond clauses.
 
   * Trac Tickets:
+    * Ticket #90 fixed.
