+changes relative to sbcl-1.0.30:
+  * improvement: stack allocation is should now be possible in all nested
+    inlining cases: failure to stack allocate when equivalent code is manually
+    open coded is now considered a bug.
+  * new feature: experimental :EMIT-CFASL parameter to COMPILE-FILE can
+    be used to output toplevel compile-time effects into a separate .CFASL
+    file.
+  * optimization: COERCE to VECTOR, STRING, SIMPLE-STRING and recognizable
+    one-dimenstional subtypes of ARRAY is upto 70% faster when the coercion is
+    actually needed.
+  * optimization: division of floating point numbers by constants uses
+    multiplication by reciprocal when an exact reciprocal exists.
+  * optimization: multiplication of single- and double-floats floats by
+    constant two has been optimized.
+  * optimization: ARRAY-IN-BOUNDS-P is resolved at compile-time when
+    sufficient type information is available. (thanks to Leslie Polzer)
+  * improvement: a STYLE-WARNING is signalled when a generic function
+    clobbers an earlier FTYPE proclamation.
+  * improvement: the compiler is able to track the effective type of
+    generic function across method addition and removal even in the
+    absence of an explicit DEFGENERIC.
+  * improvement: DESCRIBE now reports on symbols naming undefined
+    but assumed or declared function as well.
+  * improvement: recompilation of systems using SB-GROVEL now works
+    (thanks to Leslie Polzer)
+  * improvements to SB-CLTL2 (thanks to Larry D'Anna):
+    ** functions DECLARATION-INFORMATION, PARSE-MACRO, and ENCLOSE have been
+       documented.
+    ** DECLARATION-INFORMATION now supports declaration name DECLARATION as
+       well.
+  * improvement: improved address space layout on OpenBSD (thanks to Josh
+    Elsasser)
+  * bug fix: a failing AVER in CONVERT-MV-CALL has been fixed. (thanks to
+    Larry D'Anna)
+  * bug fix: SLEEP supports times over 100 million seconds on long on OpenBSD
+    as well. (reported by Josh Elsasser)
+  * bug fix: DELETE-FILE on streams no longer closes the stream with :ABORT T,
+    leading to possible attempts to delete the same file twice. See docstring
+    on DELETE-FILE for details. (reported by John Fremlin)
+  * bug fix: the low-level debugger had 32-bit assumptions and was missing
+    information about some array types. (thanks to Luis Oliveira)
+  * bug fix: moderately complex combinations of inline expansions could
+    be miscompiled if the result was declared to be dynamic extent.
+  * bug fix: in some cases no compiler note about failure to stack allocate
+    was emitted, even if the objects were in fact heap allocated.
+  * bug fix: minor violation of "otherwise inaccessible" rule for stack
+    allocation could cause objects users might reasonably expect to
+    be heap allocated to be stack allocated.
+  * bug fix: DESCRIBE signalled an error for generic functions under
+    certain circumstances. (thanks to Leslie Polzer)

   * minor incompatible change: SB-THREAD:JOIN-THREAD-ERROR-THREAD and
     SB-THREAD:INTERRUPT-THREAD-ERROR-THREAD have been deprecated in favor
     of SB-THREAD:THREAD-ERROR-THREAD.
