+ ** ALLOCATE-INSTANCE now works on structure classes defined via
+ DEFSTRUCT (and not just by those from DEFCLASS :METACLASS
+ STRUCTURE-CLASS).
+ ** SLOT-EXISTS-P now works on conditions, as well as structures
+ and CLOS instances.
+ ** MAKE-LOAD-FORM now has the required methods on
+ STRUCTURE-OBJECT, CONDITION and STANDARD-OBJECT.
+ ** MAKE-LOAD-FORM-SAVING-SLOTS no longer returns a special
+ keyword, and now implements the SLOT-NAMES argument.
+ ** methods with &OPTIONAL arguments no longer allow too many
+ arguments to be passed in the call without error.
+ ** DEFGENERIC now checks that the :ARGUMENT-PRECEDENCE-ORDER
+ option is consistent with the required arguments of the generic
+ function lambda list.
+ * bug fix: REQUIRE accepts a string designator. (Thanks to
+ Antonio Martinez.)
+ * bug fix: SB-MOP:DIRECT-SLOT-DEFINITION-CLASS and
+ SB-MOP:EFFECTIVE-SLOT-DEFINITION-CLASS now have the
+ specified-by-AMOP lambda list of (CLASS &REST INITARGS).
+ * bug fix: The compiler now checks for duplicated variables in macro
+ lambda lists.
+ * bug fix: SETQ on globals returns the correct value.
+ * fixed bug 47.d: (DEFGENERIC IF (X)) now signals a PROGRAM-ERROR,
+ not a COMPILER-ERROR (followed by some other strange error on
+ choosing the CONTINUE restart).
+ * bug fix: make.sh and friends are now more consistent in the way that
+ they look for GNU "make".
+
+changes in sbcl-0.8.1 relative to sbcl-0.8.0:
+ * minor incompatible change: some nonsensical specialized lambda
+ lists (used in DEFMETHOD) which were previously ignored now signal
+ errors.
+ * minor incompatible change: the system is now aware of the types of
+ variables in the COMMON-LISP package, and will signal errors for
+ most violations of these type constraints (where previously they
+ were silently accepted).
+ * minor incompatible change: COMPILE-FILE now uses the freedom
+ afforded (ANSI 3.2.2.3) to use derived function types for
+ functions defined in the same file. This also permits the system
+ to warn on static type mismatches and function
+ redefinition. (Currently it does not work with high DEBUG level.)
+ * changes in type checking closed the following bugs:
+ ** type checking of unused values (192b, 194d, 203);
+ ** template selection based on unsafe type assertions (192c, 236);
+ ** type checking in branches (194bc).
+ * VALUES declaration is disabled.
+ * a short form of VALUES type specifier has ANSI meaning (it has
+ increased the number of situations when SBCL cannot perform type
+ checking).
+ * fixed bug in DEFSTRUCT: once again, naming structure slots with
+ keywords or constants is permissible.
+ * STREAM-READ-SEQUENCE and STREAM-WRITE-SEQUENCE now have methods
+ defined on the relevant FUNDAMENTAL-BINARY-{INPUT,OUTPUT}-STREAM
+ classes. (thanks to Antonio Martinez)
+ * improved ANSIness in DESCRIBE: The DESCRIBE function no longer
+ outputs FRESH-LINE or TERPRI, and no longer converts its stream
+ argument to a pretty-print stream. Instead, it leaves any such
+ operations to DESCRIBE-OBJECT methods.
+ * bug fix: APROPOS now respects the EXTERNAL-ONLY flag. (reported
+ by Teemu Kalvas)
+ * bug fix: NIL is now a valid destructuring argument in DEFMACRO
+ lambda lists. (thanks to David Lichteblau)
+ * bug fix: defining a generic function with a :METHOD-CLASS being a
+ subclass of STANDARD-METHOD no longer causes stack exhaustion.
+ (thanks to Gerd Moellmann)
+ * fixed bug 246: increased compilation speed of long
+ MULTIPLE-VALUE-BIND (and likewise of NTH-VALUE with a constant
+ integer argument).
+ * a contributed module implementing COMPILER-LET and MACROEXPAND-ALL
+ has been included.
+ * DEFCONSTANT now throws a condition of type
+ SB-EXT:DEFCONSTANT-UNEQL if it is being asked to redefine a
+ constant to a non-EQL value; CONTINUE and ABORT restarts
+ respectively change and preserve the value.
+ * fixed bug 63: the code walker, part of the implementation of CLOS,
+ is better at handling symbol macros.
+ * bug fix: there is no longer a type named LENGTH. (reported by
+ Raymond Toy)
+ * bug fix: in macro-like defining macros/special operators the
+ implicit block does not enclose lambda list.
+ * fixed bugs 10 and 43: VALUES, AND, OR and MEMBER are not suitable as
+ atomic type specifiers, and their use properly signals an error now.
+ * bug fix: an argument count mismatch for a type specifier in code
+ being compiled no longer causes an unhandled error at compile
+ time, but signals a compile-time warning.
+ * fixed simple vector readable printing.
+ * bug fix: DESCRIBE takes more care over whether the class
+ precedence list slot of a class is bound before accessing it.
+ (reported by Markus Krummenacker)
+ * bug fix: FORMATTER can successfully compile pretty-printer format
+ strings which use variants of the ~* directive inside.
+ * bug fix: SEARCH now applies its TEST predicate to the elements of
+ the arguments in the correct order. (thanks to Wolfhard Buss)
+ * fixed some bugs revealed by Paul Dietz' test suite:
+ ** NIL is now allowed as a structure slot name.
+ ** arbitrary numbers, not just reals, are allowed in certain
+ circumstances in LOOP for-as-arithmetic clauses.
+ ** multiple class redefinitions before slot access no longer
+ causes a type error.
+ ** (SETF FIND-CLASS) now accepts NIL as an argument to remove the
+ association between the name and a class.
+ ** generic functions with non-standard method-combination and over
+ five methods all of which return constants no longer return NIL
+ after the first few invocations. (thanks to Gerd Moellmann)
+ ** CALL-NEXT-METHOD with no arguments now passes the original
+ values of the arguments, even in the presence of assignment.
+ ** functions [N]SUBST*, LAST, NRECONC, [N]SUBLIS may return any
+ object.
+ ** DISASSEMBLE works with closures and funcallable instances.
+ ** ADD-METHOD now returns the generic function, not the new
+ method.
+ ** FIND-METHOD signals an error if the lengths of the specializers
+ is incompatible with the generic function, even if the ERRORP
+ argument is true.
+ ** TYPE-OF returns recognizeable subtypes of all built-in-types of
+ which its argument is a member.
+ ** DEFCLASS only redefines the class named by its class-name
+ argument if that name is the proper name of the class;
+ otherwise, it creates a new class.
+ ** SLOT-UNBOUND now correctly initalizes the CELL-ERROR-NAME slot
+ of the UNBOUND-SLOT condition to the name of the slot.
