+changes in sbcl-0.8.19 relative to sbcl-0.8.18:
+ * new port: SBCL now works in native 64-bit mode on x86-64/Linux
+ platform. The port supports 61-bit fixnums, large memory spaces
+ and reloading shared object files.
+ * enhancement: saving cores with foreign code loaded is now
+ supported on ppc/Darwin in addition to the previously supported
+ platforms.
+ * bug fix: invalid :DEFAULT-INITARGS are detected in compiled calls
+ to MAKE-INSTANCE.
+ * bug fix: defaulted initargs are passed to INITIALIZE-INSTANCE and
+ SHARED-INITIALIZE methods from compiled calls to MAKE-INSTANCE.
+ * bug fix: COERCE to (COMPLEX FLOAT) of a complex number no longer
+ produces an error. (thanks to Vincent Arkesteijn)
+ * bug fix: NAMESTRING on pathnames with :WILD components in their
+ directories works correctly. (thanks to Artem V. Andreev)
+ * fixed bug 125: compiler preserves identity of closures. (reported
+ by Gabe Garza)
+ * build fix: fixed the dependence on *LOAD-PATHNAME* and
+ *COMPILE-FILE-PATHNAME* being absolute pathnames.
+ * on x86 compiler partially supports stack allocation of dynamic-extent
+ closures.
+ * fixed some bugs related to Unicode integration:
+ ** encoding and decoding errors are now much more robustly
+ handled; it should now be possible to recover even from invalid
+ input or output to the terminal. (thanks to Teemu Kalvas)
+ ** provided a first cut at implementing STRING-TO-OCTETS and
+ OCTETS-TO-STRING. (thanks to Robert J. Macomber)
+ ** altered the SB-MD5 contributed module slightly, changing the
+ interface just enough for it to be supportable for builds where
+ lisp characters are not eight bits.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** the FORMATTER-generated functions for ~V[ conditionals require
+ the correct number of arguments.

changes in sbcl-0.8.18 relative to sbcl-0.8.17:
* new feature: reloading changed shared object files with
LOAD-SHARED-OBJECT now causes the new definitions to take effect.
+ * new feature: references to foreign variables and functions
+ can now be compiled and loaded before the corresponding shared
+ object file is loaded, as long as the foreign definitions are
+ available at runtime.
* Solaris 10 (aka SunOS 5.10) on the SPARC platform is now
supported. (thanks to Dan Debertin)
+ * SB-ALIEN enums can now be represented in Lisp by any symbols, not
+ just keywords. (thanks to Vincent Arkesteijn)
* fixed bug #331: structure-class instances corresponding to
DEFSTRUCT forms are now created eagerly.
* fixed bug #345: backtraces from calls to undefined functions work
* bug fix: as specified by AMOP, an error is signalled if a
class-option appears multiple times in a DEFCLASS form. (reported
by Bruno Haible)
+ * bug fix: RANDOM can be compiled when the compiler derives the type
+ of its numeric argument as a disjoint set of small integers.
+ (reported by Paul Dietz)
+ * bug fix: starting a core saved with shared objects loaded when
+ those objects are not available no longer causes threaded SBCL to
+ hang. (reported by Sean Ross)
+ * bug fix: evaluated FUNCTION no longer bypasses encapsulation (eg.
+ TRACE).
+ * bug fix: (SETF MACRO-FUNCTION) now accepts an optional environment
+ argument, which must always be NIL. (reported by Kalle Niemitalo)
+ * bug fix: printing 1.0d+23 no longer results in an error.
+ (reported by Rolf Wester for CMUCL; bug fix from Raymond Toy)
+ * bug fix: structure slot setters preserve evaluation order. (thanks
+ to Gabor Melis)
+ * fixed some bugs related to Unicode integration:
+ ** RUN-PROGRAM can allow its child to take input from a Lisp
+ stream. (reported by Stefan Scholl)
+ ** ASDF-INSTALL successfully downloads .tar.gz files in all
+ locales. (reported by Ken Causey)
* fixed some bugs revealed by Paul Dietz' test suite:
** INCF, DECF and REMF evaluate their place form as specified in
CLtS 5.1.3.
+ ** FORMATTER expands ~{ ~} iteration directives with V or #
+ parameters correctly.
+ ** FORMATTER deals with the ~@[ ~] conditional directive where the
+ consequent uses no arguments correctly.
+ ** the system has a partial understanding of the (COMPLEX RATIO)
+ type specifier.
+ ** UPGRADED-COMPLEX-PART-TYPE obeys the lattice upgrading rules
+ required.
