+changes in sbcl-1.0.11 relative to sbcl-1.0.10:
+  * incompatible change: hash-table accessor functions are no longer
+    automatically protected by locks. Concurrent accesses on the same hash-table
+    from multiple threads can give inconsistent results or even corrupt the
+    hash-table completely. Multi-threaded applications should do their own
+    locking at the correct granularity. In the current implementation it is
+    still safe to have multiple readers access the same table, but it's not
+    guaranteed that this property will be maintained in future releases.
+  * minor incompatible change: (SETF MUTEX-VALUE) is not longer supported,
+    and will signal an error at runtime.
+  * enhancement: SB-THREAD package now exports a semaphore interface.
+  * enhancement: CONS can now stack-allocate on x86 and
+    x86-64. (Earlier LIST and LIST* supported stack-allocation, but
+    CONS did not.)
+  * enhancement: nested lists can now be stack allocated on
+    platforms providing stack allocation support.
+  * enhancement: dynamic-extent support has been extended to support
+    cases where there are multiple possible sources for the stack
+    allocated value.
+  * optimization: RELEASE-MUTEX no longer needs to perform a syscall
+    if the mutex is uncontested on Linux.
+  * bug fix: symbol-macro expansion now uses the *MACROEXPAND-HOOK*
+    as specified by the CLHS. (thanks to Tobias Rittweiler)

   * bug fix: SB-EXT:COMPARE-AND-SWAP was non-atomic unless the compiler
