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.

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).
