+changes relative to sbcl-1.0.52:
+  * enhancement: on 64-bit targets, in src/compiler/generic/early-vm.lisp,
+    the parameter n-fixnum-tag-bits may now vary from 1 (fixnum =
+    (signed-byte 63)) to 3 (fixnum = (signed-byte 61)) at build-time.
+  * enhancement: SB-EXT:WAIT-FOR allows waiting for arbitrary events.
+  * minor(?) incompatible(?) change: The default fixnum width on 64-bit
+    targets is now 63 bits (up from 61).
+  * enhancement: DESCRIBE now reports a lambda-list and source location
+    for complext setf-expanders.
+  * bug fix: PUSH, PUSHNEW, POP, REMF, INCF, DECF, DEFINE-MODIFY-MACRO,
+    GETF, LOGBITP, LDB, and MASK-FIELD now arrange for non-primary values
+    of multiple-valued places to be set to NIL, instead of signalling an
+    error (per a careful reading of CLHS 5.1.2.3).
+  * bug fix: floating-point traps now work on darwin/x86 and /x86-64.
+  * bug fix: repair crash in x86oid darwin signal handling emulation
+    when built with certain compilers.
+  * bug fix: SB-ROTATE-BYTE misrotated to the right when using constant
+    rotation arguments on x86-64. (lp#882151)
+  * bug fix: low-level control flow optimisations could result in bogus
+    code in functions with tail and non-tail calls to local functions on
+    x86oids. (lp#883500)
+  * bug fix: on SPARC/:sb-unicode, avoid crashing the assembler by trying
+    to emit literal characters > (code-char 4095), for comparisons with
+    constant characters.
+  * bug fix: ROOM reported only the low 32 bits of dynamic space usage
+    on 64 bit platforms. (lp#881445)
+  * bug fix: DELETE-FILE did not MERGE-PATHNAMES, making it possible to
+    delete the wrong file when using relative pathnames. (lp#882877)
+  * bug fix: optimized SEARCH of vectors-on-vectors mishandled zero-length
+    sequences and :KEY NIL.
+
+changes in sbcl-1.0.52 relative to sbcl-1.0.51:
+  * enhancement: ASDF has been updated to version 2.017.
+  * enhancement: the --core command line option now accepts binaries with
+    an embedded core.
+  * enhancement: when built with :sb-core-compression, core files (regular
+    or executable) can be compressed with zlib.  Use the :COMPRESSION
+    argument to SAVE-LISP-AND-DIE to specify a compression level.
+  * enhancement: --[no-]merge-core-pages determines whether the runtime
+    hints the operating system that identical core pages between SBCL
+    processes should share the same physical memory.  Default is to only
+    enable this for compressed cores.
+  * optimization: SLEEP no longer conses.
+  * optimization: *PRINT-PRETTY* no longer slows down printing of strings
+    or bit-vectors when using the standard pretty-print dispatch table.
+  * bug fix: non-function FTYPE declarations no longer cause a compiler-error.
+    (lp#738464)
+  * bug fix: compiler-errors causes by MEMBER types in conjunction with with
+    AREF, CHAR, etc. (lp#826971)
+  * bug fix: compiler-errors causes by integer arguments with composed of
+    multiple ranges to ARRAY-IN-BOUNDS-P. (lp#826970)
+  * bug fix: ,@ and ,. now signal a read-time error for certain non-list
+    expressions. (lp#770184)
+  * bug fix: complex single float literals are correctly aligned when used
+    as arguments of arithmetic operators.
+  * bug fix: on 32-bit platforms, rounding of double floats larger than a
+    fixnum is correct.  (reported by Peter Keller)
+  * bug fix: stray FD-HANDLERs are no longer left lying around after unwinds
+    from RUN-PROGRAM.  (lp#840190, reported by Dominic Pearson; fix from Max
+    Mikhanosha)
+  * bug fix: redefining classes such that slots with custom allocation are
+    added or removed works again.

+changes in sbcl-1.0.51 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.
