+changes relative to sbcl-1.1.7:
+ * enhancement: RUN-PROGRAM supports a :DIRECTORY argument to set
+ the working directory of the spawned process.
+ (lp#791800) (patch by Matthias Benkard)
+ * enhancement: vectors can now be stack-allocated on PPC.
+ * enhancement: "fixed objects" can now be stack-allocated on PPC.
+ * enhancement: WITH-PINNED-OBJECTS no longer conses on PPC/GENCGC.
+ * enhancement: (sb-introspect:find-definition-sources-by-name x :vop) now
+ also returns VOPs which do not translate any functions.
+ * bug fix: type derivation for LOG{AND,IOR,XOR} scales linearly instead
+ of quadratically with the size of the input in the worst case.
+ (lp#1096444)
+ * bug fix: handle errors when initializing *default-pathname-defaults*,
+ sb-ext:*runtime-pathname*, sb-ext:*posix-argv* on startup, like character
+ decoding errors, or directories being deleted.
+ * bug fix: Loading a core with a discontiguous dynamic space now correctly
+ computes the amount of dynamic space used.
+ * bug fix: disassembler missing ",8" on SHLD
+ * optimization: faster ISQRT on fixnums and small bignums
+ * optimization: faster and smaller INTEGER-LENGTH on fixnums on x86-64.
+
+changes in sbcl-1.1.7 relative to sbcl-1.1.6:
+ * enhancement: TRACE :PRINT-ALL handles multiple-valued forms.
+ (lp#457053)
+ * bug fix: :allocation slot option works for condition slots
+ (lp#1049404)
+ * bug fix: redefining conditions does not lead to multiple evaluations of
+ hairy slot initfunctions anymore (lp#1164969)
+ * bug fix: CLASS-DIRECT-DEFAULT-INITARGS now works for condition classes
+ (lp#1164970)
+ * bug fix: function constants now work as initforms and default initarg
+ values of conditions (lp#539517)
+ * bug fix: svref/(setf svref) on symbol macros don't crash the compiler
+ anymore. (Minimal test case provided by James M. Lawrence on sbcl-devel)
+ * bug fix: no more bogus ## references when pretty printing backquoted
+ forms with non-trivial structure sharing. (lp#1161218)
+ * bug fix: Don't signal an error on (setf (documentation nil 'function)
+ "doc"). Signal a style-warning instead when trying to set documentation
+ of NIL for all other documentation types. (Reported by Zach
+ Beane; regression since 2e52fa05.)
+ * bug fix: modular arithmetic involving large constants and conditionals
+ should no longer result in spurious dead code elimination. (Reported by
+ Eric Marsden).
+ * bug fix: our mach exception handler can seemingly called very early in
+ the program execution process on OS X 10.8.0. Try and handle that case
+ robustly, without potentially leaking mach ports too much.
+ * optimization: LOGBITP and LOGTEST optimizations from x86 ported to x86_64.
+
+changes in sbcl-1.1.6 relative to sbcl-1.1.5:
+ * enhancement: the continuable error when defknown-ing over extant
