This feature is not currently supported on all SBCL + platforms. (thanks to James Bielman and NIIMI Satoshi) + * new feature: a generational or ephemeral garbage collector is now + the default on the PowerPC platform (both Linux and Darwin). The + old Cheney (stop and copy) collector is a build-time option. + (thanks to Cyrus Harmon, after Raymond Toy) + * 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, even using the older Cheney garbage collector. + * 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) + * fixed bug: the Power PC assembly code for calling into lisp + sometimes computed its return address wrongly (depending on the + 15th bit of the address, fixed at link time). This used to + manifest itself in a segmentation violation while building PCL. + (reported by Kevin Rosenberg, Eric Marsden, Lars Brinkhoff and + many others over the years) + * fixed bug: ROOM no longer reports silly numbers for stack usage if + the stack pointer (treated as a signed integer) is negative. + (thanks to Peter van Eynde) + +changes in sbcl-0.9.9 relative to sbcl-0.9.8: + * new platform: experimental support for the Windows operating + system has been added.
