 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: simple uses of HANDLER-CASE and HANDLER-BIND no
     longer cons.
+  * optimization: file compiler is now able to coalesce non-circular

   * bug fix: EAI_NODATA is deprecated since RFC 3493. Stop using it
