+ ** fixed handling of invalid NIL arguments in keyword position
+ in local calls.
+ ** fixed non-pretty printing of arrays with *PRINT-RADIX* being
+ true.
+ ** provided a readably-printable representation for RANDOM-STATE
+ objects.
+ ** ensured that pathnames, where they have a namestring, always
+ print using #P"..." syntax.

+changes in sbcl-0.8.12 relative to sbcl-0.8.11:
+ * minor incompatible change: the system no longer provides
+ optimization hints (conditions which are TYPEP
+ SB-EXT:COMPILER-NOTE) for conforming code in default compilation
+ mode; these hints are still emitted when higher SPEED optimization
+ is requested.
+ * new contrib module: a sampling profiler (profiling by statistical
+ sampling, rather than by instrumenting functions) is available as
+ the SB-SPROF contrib. (thanks to Gerd Moellmann and Juho Snellman)
+ * the behaviour of the standard function ED is now customizeable by
+ third parties through a hook variable: see ED's documentation
+ string for information on the protocol.
+ * the compiler no longer emits efficiency notes for (FUNCALL X)
+ when the type of X is uncertain under default optimization
+ settings.
+ * fixed bug 276: mutating a binding of a specialized parameter to a
+ method to something that is not TYPEP the specializer is now
+ possible.
+ * fixed bugs 45d and 118: DOUBLE-FLOAT[-NEGATIVE]-EPSILON now
+ exhibit the required behaviour on the x86 platform. (thanks to
+ Peter van Eynde, Eric Marsden and Bruno Haible)
+ * fixed bug 335: ATANH now computes the inverse hyperbolic tangent
+ even for difficult arguments. (reported by Peter Graves)
+ * fixed bug 141a: the backquote printer now descends quoted
+ structure.
+ * fixed another bug in backquote printing: no more destructive
+ modification of the form's list structure. (reported by Brian
+ Downing)
+ * fixed bug in INTERRUPT-THREAD: pin the function, so that it cannot
+ move between its address being taken and the call to
+ interrupt_thread, fixing a crashing race condition.
+ * the SB-POSIX contrib implementation has been adjusted so that it
+ no longer exhibits ridiculously poor performance when constructing
+ instances corresponding to C structs.
+
+changes in sbcl-0.8.13 relative to sbcl-0.8.12:
+ * new feature: SB-PACKAGE-LOCKS. See the "Package Locks" section of
+ the manual for details; add :SB-PACKAGE-LOCKS in
+ customize-target-features.lisp to enable them.
+ * minor incompatible change: as threatened around sbcl-0.8.0, the
+ home package of MOP-related symbols is now SB-MOP, not SB-PCL.
+ The symbols are also exported from SB-PCL for backwards
+ compatibility, but more so than before SB-PCL should be treated as
+ an implementation-internal package.
+ * the SB-SPROF contrib now works on (most) non-x86 architectures.
+ It is known as of this release not to work on the Alpha, however.
+ * fixed bug #338: instances of EQL-SPECIFIER are now valid type
+ designators and can hence be used with TYPEP.
+ * fixed bug #333: CHECK-TYPE now ensures that the type error
+ signalled, if any, has the right object to be accessed by
+ TYPE-ERROR-DATUM. (reported by Tony Martinez)
+ * fixed bug #340: SETF of VALUES obeys the specification in ANSI
+ 5.1.2.3 for multiple-value place subforms. (reported by Kalle
+ Olavi Niemetalo)
+ * fixed a bug: #\Space (and other whitespace characters) are no
+ longer considered to be macro characters in standard syntax by
+ GET-MACRO-CHARACTER.
