+changes relative to sbcl-1.0.50:
+  * minor incompatible change: SB-BSD-SOCKET socket streams no longer
+    participate in SERVE-EVENT by default: pass :SERVE-EVENTS T to
+    MAKE-SOCKET-STREAM if using SERVE-EVENT.
+  * enhancement: added support for socket keepalive timeout intervals
+    and probe counts on Linux.
+  * enhancement: building 32-bit SBCL on Linux/x86-64 now works without a
+    chroot. (Use "SBCL_ARCH=x86 sh make.sh" to build.)
+  * enhancement: added new toplevel options --quit and --non-interactive
+    (lp#822712).
+  * enhancement: the Windows port of SBCL now builds and runs on Wine
+    (thanks to Anton Kovalenko).
+  * optimization: unsigned integer divisions by a constant are implemented
+    using multiplication (affects CEILING, FLOOR, TRUNCATE, MOD, and REM.)
+  * optimization: improved type-derivation for LOAD-TIME-VALUE.
+  * 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.
+    (lp#549673)
+  * bug fix: SSE comparison instructions can be disassembled even when one
+    operand is in memory. (lp#814702)
+  * bug fix: incomplete writes when not using SERVE-EVENTS. (lp#820599)
+  * bug fix: MULTIPLE-VALUE-BIND + VALUES -> LET conversion could lose derived
+    type information associated with the VALUES form.
+  * bug fix: broken warnings/errors for type-errors involving LOAD-TIME-VALUE
+    forms. (lp#823014)
+  * bug fix: OPEN :IF-EXISTS :APPEND now returns correct FILE-POSITION before
+    first write (lp#561642).

+  * enhancement: SB-EXT:MAKE-THREAD accepts an argument list designator for

+  * 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
+    optimized. (lp#555201)
+  * optimization: MAP and MAP-INTO are more efficient for non-simple vectors,

+  * optimization: local call trampolines (x86 and x86-64) are emitted

+  * optimization: implicit value cells for dynamic-extent closed-over bindings

+  * meta-optimization: improved compilation speed, especially for large
