The + SB-ALIEN:C-STRING no longer implies an ASCII + external-format. Instead the string is subject to external-format + conversion. Additionally return values of type SB-ALIEN:C-STRING + are by default of type (SIMPLE-ARRAY CHARACTER), not + SIMPLE-BASE-STRING. For an alien type that behaves like the old + SB-ALIEN:C-STRING type, use (SB-ALIEN:C-STRING :EXTERNAL-FORMAT + :ASCII :ELEMENT-TYPE BASE-CHAR).

This makes the + class-precedence-lists of GENERIC-FUNCTION and + STANDARD-GENERIC-FUNCTION comply with the requirement of ANSI + 1.4.4.5. + * minor incompatible change: the default stream external format on + non-unicode SBCL is no longer detected from the locale, but is always + ISO-8859-1 + * new feature: Add a version of evaluator that uses an interpreter instead + of the compiler. EVAL still uses the compiler by default, to switch it + to use the interpreter, set the value of the variable + SB-EXT:*EVALUATOR-MODE* to :INTERPRET. + * minor incompatible change: the single-stepper REPL has been merged + with the normal debugger (see the "Stepping" heading of the debugger help + for more details). The debugger command STEP will no longer switch + to the single-stepper REPL. + * bug fix: ENOUGH-NAMESTRING on pathnames with no name and a pattern + for a type now works. + * bug fix: loading of default sysinit file works.

(reported by James Bielman and Attila Lendvai) + * bug fix: format strings with ~> without matching ~< no longer + trigger an AVER, but signal an understandable error instead. + (reported by Antonio Martinez) + * bug fix: specifying an output-file without a pathname-type for + COMPILE-FILE or COMPILE-FILE-PATHNAME resulted in using the type + of input-file instead of "fasl". (reported by Robert Dodier) + * bug fix: compiler-macro lambda-list parsing of FUNCALL forms. + (reported by James Y Knight). + * bug fix: compiler-macros-function did not consider the environment + argument for shadowing by local functions. + * bug fix: compiler-macros expansion was inhibited by local INLINE + declarations. + * bug fix: inline expansions of known functions were subject to + step-instrumentation in high debug policies, leading to problems + with type-inference. + * bug fix: compiler failed to differentiate between different CONS + types in some cases. + * bug fix: fixed input, output and error redirection in RUN-PROGRAM + for win32. (thanks to Mike Thomas and Yaroslav Kavenchuk) + * bug fix: #368: incorrect use of expressed vs. upgraded array + element type. + * bug fix: #306a: more precise unions of array types. + * thread-safety improvements: + ** CONDITION-WAIT could return early on Linux, if the thread was + interrupted and subsequently continued with SIGCONT. + ** STABLE-SORT and ADJUST-ARRAY were not reentrant. + +changes in sbcl-0.9.15 relative to sbcl-0.9.14: + * added support for the ucs-2 external format. (contributed by Ivan + Boldyrev) + * minor incompatible change: pretty printing of objects of type + (cons symbol) is, in the default pprint-dispatch-table, now + sensitive to whether the symbol satisfies FBOUNDP. (thanks to + Marcus Pearce) + * minor incompatible change: SB-MOP:FINALIZE-INHERITANCE is now + called later in a class's lifetime, possibly as late as when the + first instance of the class is created.

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. + * enchancement: RUN-PROGRAM is now able to extract the file-descriptor + from SYNONYM-STREAM and TWO-WAY-STEAMS provided they can be decomposed + down to an SB-SYS:FD-STREAM, allowing direct communication in + more cases.
