+ * fixed bug 307: The obsolete instance protocol ensures that
+ subclasses are properly obsoleted. (thanks to Nikodemus Siivola)
+ * on SPARC, X86 and Alpha fixed bug 298, revealed by Paul F. Dietz'
+ test suite: SBCL can remove dead unknown-values globs from the
+ middle of the stack.
+ * added a new restart to *BREAK-ON-SIGNALS* handling to make it
+ easier to resume long computations after using *BREAK-ON-SIGNALS*
+ to diagnose and fix failures. (thanks to Nikodemus Siivola)
+ * fixed bug reported by PFD in lisppaste #747 (and Bruno Haible from
+ CLISP test suite): WRITE-TO-STRING is not constant-foldable.
+ * fixed bugs in COMPLEX type specifier: UPGRADED-COMPLEX-PART-TYPE
+ is now consistent with (COMPLEX <x>); bugs in treatment of COMPLEX
+ MEMBER and UNION types have likewise been fixed. (thanks to Bruno
+ Haible)
+ * fixed a (fairly theoretical) bug in string printing: if
+ *PRINT-READABLY* is true, signal PRINT-NOT-READABLE if the string
+ does not have array-element-type equal to the most general string
+ type.
+ * fixed bug: SET-PPRINT-DISPATCH does not immediately resolve
+ function name. (thanks to Nikodemus Siivola)
+ * fixed bug: compile-time format string checker failed on
+ non-closed ~{. (reported by Thomas F Burdick)
+ * fixed bug: as reported by Kalle Olavi Niemitalo on #lisp IRC,
+ don't warn on legal loop code involving more than one aggregate
+ boolean. (thanks to Nikodemus Siivola)
+ * fixed bug: as reported by Peter Graves on #lisp IRC, passing a NIL
+ in keyword position to MAKE-PACKAGE was not being reported as
+ invalid.
+ * fixed bug: as reported by Juan Ripoll on cmucl-imp,
+ MULTIPLE-VALUE-BIND should be able to lexically bind lambda list
+ keywords.
+ * fixed bugs 280 and 312: the checking for multiple definitions in a
+ file is less likely to become confused by uses of inline
+ functions.
+ * optimization: rearranged the expansion of various defining macros
+ so that each expands into only one top-level form in a
+ :LOAD-TOPLEVEL context; this appears to decrease fasl sizes by
+ approximately 10%.
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** MAKE-INSTANCES-OBSOLETE returns the class name when called with
+ a symbol.
+ ** Fixed an optimization bug related to inheritance of initforms
+ from local to shared slots.
+ ** FILE-POSITION works as specified on BROADCAST-STREAMs.
+ ** CAST optimizer forgot to flush argument derived type.
+ ** print/read consistency on floats is now orders of magnitude
+ more likely. (thanks also to Bruno Haible for a similar report
+ and discussions)
+ ** removed stack cleaning in the cleanup part of UNWIND-PROTECT.
+ ** IMAGPART is specified (infelicitously) to return (* 0 <thing>)
+ for objects of type REAL. Make it so.
+ ** SXHASH is specified (infelicitously) to respect similarity,
+ which means that (SXHASH 0.0) must equal (SXHASH -0.0). Make
+ it so. (thanks to Markus Ziegler)
+ ** on the Alpha, the compiler succeeds in compiling functions
+ returning a known number of arguments greater than 63.
+ ** fixed handling of invalid NIL arguments in keyword position
+ in local calls.
