 changes relative to sbcl-1.0.50:
+  * enhancement: building 32-bit SBCL on Linux/x86-64 now works without a
+    chroot. (Use "SBCL_ARCH=x86 sh make.sh" to build.)
   * bug fix: correct RIP offset calculation in SSE comparison and shuffle
     instructions. (lp#814688)
   * bug fix: COERCE to unfinalized extended sequence classes now works.
