It's + somewhat counter to the intent of the protocol, I (CSR) think, and + additionally it just doesn't work in SBCL as currently + implemented, thanks to optimizations (that are always valid for + the other three SLOT-VALUEish functions, but not for the setter). + * minor incompatible change: the :SB-LDB feature is now enabled by + default, and DISABLE-DEBUGGER and ENABLE-DEBUGGER also affect + the low-level debugger. + * bug fix: class objects can be used as specializers in methods. + (reported by Pascal Costanza) + * bug fix: native unparsing of pathnames with :DIRECTORY NIL failed + with a type error. (reported by blitz_ on #lisp) + * bug fix: unparsing logical pathnames with :NAME :WILD :TYPE NIL + failed with a type error. (reported by Pascal Bourguignon) + * bug fix: merging pathnames against defaults with :DIRECTORY + starting with '(:RELATIVE :BACK) should preserve the :BACK. + (reported by James Y Knight) + * improved SB-BSD-SOCKETS support on Windows.

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.
