+changes relative to sbcl-1.1.0:
+  * enhancement: WITH-COMPILATION-UNIT no longer grabs the world-lock.
+    (COMPILE and COMPILE-FILE still do.)
+  * optimization: the SPARC backend now supports the precise generational
+    (GENCGC) garbage collection.  Enabled by default on Solaris/SPARC and
+    Linux/SPARC.  Thanks to Raymond Toy (via CMUCL).
+  * enhancement: add experimental support for the SB-THREAD feature and the
+    timer facility on Windows.  Thanks to Dmitry Kalyanov and Anton Kovalenko.
+    Threads are enabled by default, and this version of SBCL is considered
+    to be the last and final release to officially support building with
+    threads disabled.
+  * optimization: The compiler no longer rotates loops in some cases where
+    this transformation actually lead to worse code being generated.
+  * bug fix: SB-CLTL2:MACROEXPAND-ALL correctly handles shadowing of
+    symbol-macros by lexical bindings.
+  * bug fix: stack allocation was prevented by high DEBUG declaration in
+    several cases.
+  * bug fix: SB-EXT:GC-LOGFILE signaled an error when no logfile was set.
+    (thanks to SANO Masatoshi)
+  * bug fix: PARSE-NATIVE-NAMESTRING performed non-native parsing when
+    :JUNK-ALLOWED was true.
+  * bug fix: type derivation inferred overly conservative types for
+    unions of array types. (lp#1050768)
+
+changes in sbcl-1.1.0 relative to sbcl-1.0.58:
   * enhancement: New variable, sb-ext:*disassemble-annotate* for controlling
     source annotation of DISASSEMBLE output. Defaults to T.
   * enhancement: TIMEOUT arguments added to WITH-MUTEX and WITH-RECURSIVE-LOCK, and
     WAIT-P argument added to WITH-RECURSIVE-LOCK.
   * enhancement: SB-EXT:ATOMIC-PUSH and SB-EXT:ATOMIC-POP allow atomic operations
     on list heads.
+  * enhancement: Optional features (not enabled by default) allow the
+    use of signals for inter-thread synchronization to be reduced on certain
+    supported platforms (currently Linux, Solaris, and FreeBSD on x86 and
+    x86-64).  Set (and :sb-thread :sb-safepoint :sb-thruption :sb-wtimer)
+    to test these experimental features.  Known remaining bugs include minor
+    thread safety issues, less timely freeing of memory by GC, and certain
+    (not yet optimally low) runtime overhead.  Thanks to Anton Kovalenko.
   * optimization: CL:SORT and CL:STABLE-SORT of lists are faster and use fewer
     comparisons, particularly on almost-sorted inputs.
   * bug fix: Reading floats with large exponents no longer takes too much time

     into a DEFCAS defined place was used as the place.
   * bug fix: FIND and POSITION signaled a type-error when non-bits where looked
     for from bit-vectors.
+  * bug fix: a race condition around thread creation could (in SBCL 1.0.57)
+    lead to internal errors or crashes (lp#1058799).
   * documentation: a section on random number generation has been added to the
     manual. (lp#656839)
