This feature is not currently supported on all SBCL + platforms. (thanks to James Bielman and NIIMI Satoshi) + * minor incompatible change: the method by which SBCL finds its + contributed modules has changed; it no longer relies on symbolic + links from an $SBCL_HOME/systems directory, but searches directly + in the subdirectories of $SBCL_HOME. + * enhancement: the dynamic heap size on the Linux/PPC platform is + markedly larger. + * fixed bug #399: full call to DATA-VECTOR-REF in accesses to + certain complicated string types. (reported by Gary King) + * fixed bug: STRING-TO-OCTETS and OCTETS-TO-STRING did not convert + character codes. (thanks to Yaroslav Kavenchuk and Ivan Boldyrev) + * fixed bug: DOCUMENTATION on structures no longer signals an + error if no structure type of the right name exists. (reported by + Glenn Ehrlich) + * fixed bug: compiled calls to MAKE-INSTANCE where there is an + applicable non-standard primary or :AROUND method on + INITIALIZE-INSTANCE or SHARED-INITIALIZE and a non-keyword initarg + no longer cause unbound variable errors. (reported by Kevin Reid) + * fixed bug: metacircle resolution in cases where methods have slots + added before the slots from STANDARD-METHOD. (reported by Jean + Bresson) + +changes in sbcl-0.9.9 relative to sbcl-0.9.8: + * new platform: experimental support for the Windows operating + system has been added. (thanks to Alastair Bridgewater) + * fixed several bugs in and robustified the PPC FFI (including + callbacks). (thanks to Cyrus Harmon and Heiner Schwarte) + * bug fix: allow non-simple string symbol names (reported by Paul + Dietz) + * bug fix: interrupt handling on NetBSD (thanks to Richard M + Kreuter) + * bug fix: saving a core corrupted callbacks on x86/x86-64 + * bug fix: closed a loophole in metacircularity detection and + grounding in the PCL implementation of CLOS. + * bug fix: TRUENAME on "/" no longer returns a relative pathname. + (reported by tomppa on #lisp) + * bug fix: clear the direction flag on Lisp -> C transitions, as + required by the x86-64 ABI.

(thanks to NIIMI Satoshi) + +changes in sbcl-0.9.8 relative to sbcl-0.9.7: + * minor incompatible change: (SETF CLASS-NAME) and (SETF + GENERIC-FUNCTION-NAME) are generic functions once more (reverting + the change in the 0.9.7 release). (SETF CLASS-NAME) is specified + by ANSI as a generic function, and for consistency (SETF + GENERIC-FUNCTION-NAME) is treated likewise. + * fixed bug #233.b: make constraint propagation notice when a variable + value is changed after it is referenced but before it is used + * fixed bug #296: no more arbitrary behaviour from filenames with + odd characters as --load arguments. (reported by Adam Warner) + * fixed bug #390: :CHARACTER-SET pathname components now work as + expected. (reported by Tim Daly Jr) + * fixed bug #391: complicated :TYPE intersections in slot + definitions no longer cause an error in PCL internals. + * fixed bug #392: plugged a hole in the obsolete-instance protocol. + * bug fix: FILE-STRING-LENGTH is now external-format sensitive, + returning the number of octets which would be written to the + file-stream. (thanks to Robert J. Macomber) + * bug fix: the SB-SIMPLE-STREAMS contrib passes external-format + arguments to the internal stream functions. (thanks to David + Lichteblau) + * bug fix: stack exhaustion is now handled on the x86/SunOS + platform. (thanks to Daisuke Homma) + * bug fix: more accurate ROOM results on GENCGC platforms + * optimization: improved type inference for arithmetic-for + index variables in LOOP + * optimization: faster floating-point SQRT on x86-64 + * fixed some bugs revealed by Paul Dietz' test suite: + ** DOCUMENTATION returns NIL instead of "" for method combinations + that don't have a docstring + +changes in sbcl-0.9.7 relative to sbcl-0.9.6: + * minor incompatible change: (SETF CLASS-NAME) and (SETF + GENERIC-FUNCTION-NAME) are no longer generic functions, and + therefore are not customizeable by user code (as seems to be at + least permitted and maybe required by AMOP). As a consolation, + however, the SBCL implementation of these functions now calls + REINITIALIZE-INSTANCE as specified by AMOP. + * bug fix: slot-definition documentation is propagated as per ANSI + 7.6.2 to EFFECTIVE-SLOT-DEFINITIONS. + COMPUTE-EFFECTIVE-SLOT-DEFINITION now receives a :DOCUMENTATION + argument, as do eslotd initialization methods. (from Pascal + Costanza's "Closer" project) + * bug fix: REINITIALIZE-INSTANCE on generic functions calls + COMPUTE-DISCRIMINATING-FUNCTION (almost) unconditionally, as + specified by AMOP. + * bug fix: it is now possible to have more than one subclass of + STANDARD-GENERIC-FUNCTION without causing stack overflow. + (reported by Bruno Haible, Pascal Costanza and others) + * bug fix: the dependent update protocol now works for generic + functions.
