+ * enhancement: SB-POSIX improvements:
+ ** WNOHANG and WUNTRACED are exported.
+ ** SYSCALL-ERROR now also provides the name of the failing system call.
+ * enhancement: --script improvements:

+ cause scripts to exit silently, making them easier to use in shell
+ pipelines.
+ ** backtraces from scripts now go to standard error instead of the
+ terminal even if one is available.
+ ** --script can be an argument, causing the script to be loaded from
+ standard input.
+ * enhancement: MAKE-ALIEN-STRING provides an easy way to transport lisp
+ strings to foreign memory.
+ * enhancement: (SETF GC-LOGFILE) allows logging garbage collections to
+ a file, making it easier to understand heap dynamics.

+ allows the compiler to automatically elide rest-list allocation so long as
+ the call sites are in functions that the compiler knows cannot escape.
+ (lp#504575)
+ * optimization: CALL-NEXT-METHOD using explicit arguments is faster,
+ especially in safe code when none of the required arguments have changed
+ their identities.

+ uninterruptible, as well as blocking reads from socket streams created
+ with for which :SERVE-EVENTS NIL. (regression from 1.0.42.43)

+ a compile-time error. (lp#720382)
+ * bug fix: forms such as (FUNCALL (FUNCTION NAME OOPS) ...) were compiled
+ without complaints.
+ * bug fix: less verbose source forms for functions from EVAL. (lp#747485)

+ could exhaust stack.

+ (lp#721087)
+ * bug fix: under rare circumstances, constraint propagation could rewrite a
+ variable reference to refer to a variable not in scope, causing an error
+ during physical environment analysis when attempting to close over the
+ variable. (lp#551227)

+ * optimization: optimized constructors are used for MAKE-INSTANCE of classes

+ * bug fix: incorrect FILE-POSITION on streams opened using :EXTERNAL-FORMAT
+ :DEFAULT when the default external had character size other than 8 bits.
