+  * 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.
+    (reported by Jan Moringen; lp#815155)
+  * bug fix: a compiler error during typecheck generation, reported by Eric
+    Marsden. (lp#816564)
+  * bug fix: obsolete instance protocol fires when shared slots are added
+    or removed.
+  * bug fix: fixed-format floating point printing with scaling factors.
+    (lp#811386)
+  * bug fix: using GCC >= 4.6 to build SBCL on x86 no longer breaks
+    backtraces. (lp#818460)
+  * bug fix: better backtraces for interrupted syscall frames on x86.

+  * enhancement: SB-ALIEN exports alien type specifiers SIZE-T and OFF-T.
+  * enhancement: debugger understands &MORE arguments better.
+  * optimization: extracting bits of a single-float on x86-64 has been

+  * optimization: MAP and MAP-INTO are more efficient for non-simple vectors,
