 changes in sbcl-1.0.18 relative to 1.0.17:
+  * minor incompatible change: SB-SPROF:WITH-PROFILING now by default
+    profiles only the current thread.
+  * minor incompatible change: changes to SYMBOL-VALUE of constants
+    defined with DEFCONSTANT now signal an error.
+  * enhancement: SB-SPROF now has support for wallclock profiling,
+    and is also able to profile specific threads. REPORT output
+    has also additional sorting options.
   * optimization: structure allocation has been improved
     ** constructors created by non-toplevel DEFSTRUCTs are ~40% faster.
     ** out of line constructors are ~10% faster.

     ** inline constructors are capable of dynamic extent allocation
        (generally on x86 and x86-64, in some cases on other platforms
        as well.)
+  * optimization: simple uses of HANDLER-CASE and HANDLER-BIND no
+    longer cons.
+  * optimization: file compiler is now able to coalesce non-circular
+    lists, non-base strings, and bit-vectors. Additionally, constants
+    are never referenced through SYMBOL-VALUE at runtime.
+  * bug fix: EAI_NODATA is deprecated since RFC 3493. Stop using it
+    in sb-bsd-sockets.
+  * fixed some bugs revealed by Paul Dietz' test suite:
+    ** NIL is a valid function name (regression at 1.0.13.38)
+    ** FILL on lists was missing its return value (regression at 1.0.12.27)
+    ** STRING-TRIM, STRING-LEFT-TRIM, and STRING-RIGHT-TRIM did not respect
+       fill pointers properly (regression at 1.0.12.23)
+    ** STRING-TRIM, STRING-LEFT-TRIM, and STRING-RIGHT-TRIM did not respect
+       displacement indices properly (regression at 1.0.12.23)

   * temporary regression: user code can no longer allocate closure
