+ * 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.
